Thanks for the video. My problem seems to be different than this. I also have a craftsman 1/2 hp opener and can't get the door to reverse until it opens all the way. I stop it (with the switch) in the partially open position, and when I restart it, it continues on up until fully open. Then it often takes several tries to get the door to close.

Thank you for you r help on my garage door i notice the chain on the right side as you look from inside out is sagging so what do i do adjust the quarter turn screw on the back of the lift first? Thank you for your help.

[@TheMaintenanceMan]

Is it sagging when the door is up, down, or all the time?

[@MrDoubleYa]

Great video and I was hoping you could give some tips on my garage door problem. My garage door will sometimes close then immediately open. I have to use the remote several times to close the garage door. After watching this behavior from both sides of the door I noticed 2 things: 1) from the outside when this situation occurs the door looks bowed (does not happen when door closes on first try) and 2) from the inside when this situation occurs the track bows up towards the ceiling of the garage. Any ideas on how to fix? I check the sensors and they are working and lined up. This is a craftsman door opener.

[@TheMaintenanceMan]

The down limit setting is set to far. It forces the door down to the ground to hard and can cause both the bowing of the track and the door. Adjust the down travel limit and back it off a quarter turn at a time till the door isn’t forced down so hard and it should help. Let me know if you encounter any other issues.

[@law4all09]

[@Medero1959]

hello from texas excellent video I want to ask you a question it is natural that the engine moves a little when closing the door I see that everything is well adjusted

[@TheMaintenanceMan]

How far is a little? It’s normal for the lift motor assembly to move only if the mounts are loose. If its moving an inch there’s a problem. If its just wiggling I’d keep an eye on it. Ultimately it should be secure.

[@noneyabiznazz]

Hey great video! I had this happen last year where the chain on 1 side was so loose the trolley hit the stop bolt on the up bolt and jammed It was so tight on the opisite side of the threaded bolt to loosen the chain that it would not move at all and I was worried it was gonna snap the pulley any second. After loosening the chain and taking a huge chance on getting hurt I pulled the chain off the gear on top of the motor and then put it back on after the tension was off. It has done the same thing 3 more times this year. It will be working fine then all of a sudden it will hit a stop bolt (has hit the up and down side) and 1 side of the chain will be hanging there several inches below the rail and the other side so tight I'm surprised it doesn't snap the gear or pulley. When I fix it I have used your video in the past and had the tension good on both sides. What is causing it to get so loose on the one side?

[@TheMaintenanceMan]

Sounds like you may have a broken spring. What you’re describing sounds like the chain may be handling the full weight of the door. Another possibility is that your chain is entirely too loose. If you Disconnect the door from the chain trolley and both sides of the chain are even with tension then check the springs. Also check to see if the chain does that with no load on it. Disconnect the door and just run it. Does the chain perform as you have described above.

[@noneyabiznazz]

Ask The Maintenance Man Thank you for replying so quick! I'm about to "fix" it again.. quick question though if you don't mind. The trolley hit the stop by the door and is bound so tight on the side opposite of the threaded adjuster I am seriously surprised the gear hasn't snapped off. Is there a way to release some of that tension before pulling the chain off? I loosen it almost all the way then pull the slack to the gear, but its got so much force on the teeth that I have to pry the chain off the first few teeth. This either poops the chain off or skips several links and catches with authority. Put it this way, last time I set my camera at the door so that if the gear gets snapped off like a dull ninja star to the face we will have a video for the ER so I don't have to explain it over and over. (Probably a how-not-to video for utube as well) Thanks for your time

[@TheMaintenanceMan]

I’d put the door half way and stop it. Then pull the door detach lever and see if the carriage holder will travel like normal without the door. If it still gets bound up on the end as you have described, you’re down limit is set too far. It’s like the door is trying to close beyond the ground. Just back that limit off a bit and it should take care of the pressure when the carriage is all the way forward. Feel free to email me with a video of how it’s not functioning correctly so that I can better help you diagnose how to fix it. Just make sure that the video is not blurry. Let me know how I can help.

[@kensahadeo1927]

Hey Maintenance man, my craftsman chain drive door opener snapped the sprocket. I have replaced it but not I cannot seem to get the adjustments right. It opens too much to where the rail is bowed out. How do I get it back to where I have no to little tension and then work from there? it opens and closes to where it hit the 'stop' bolt and by then the rail is bowed out from too much tension. I have to undo the chain to release the tension. So I am guessing it is travelling too far up 7 down but I cannot reset it tow where is travels a short distance and then I can keep increasing the travel distance. What do you recommend? thanks

[@kimberlykareus1177]

My dad and I installed the opener the garage door was installed by a professional.

It seems like it's sticking or something we tried adjusting the arm that connects the opener to be the door? We are stumped?

[@lathanos2011]

Excuse me for not knowing the part name, but the part of the garage door that is sort of like a carriage, the part that when you pull the emergency release that the door pops out of, but stays attached to the rail where the chain is. Is there a way to move that piece forward or backwards to release tension? Or would I have to go purchase a shorter arm (the part that attaches to the garage and is cotter pinned to the part that releases the door when you pull the emergency release? I hope that make sense. Any help would be appreciated.

[@TheMaintenanceMan]

The curved arm is typically constructed of two pieces that are bolted together. You can extend or shorten the arm for large adjustments. Otherwise the only other adjustments for the travel of the trolley (where the arm attaches) are the travel limit adjustments described in the video. Hope that helps.

Legacy 850 stops about 3" from the ground. Someone said the big spring was bad. Is that true? Is there anything else that could be causing this. I unlatched it and rest it. Also tried the push button reset adjustment. And neither worked.

[@TheMaintenanceMan]

If the big spring is bad you’ll be able to see where it’s broken. The down adjustment is what will get the door 3 inches down further.

[@larespuertorico]

what about the rail how much play should it have while the door raises ?

[@TheMaintenanceMan]

My apologies for the late response. As far as “play” in the track rail, there shouldn’t be any. The rail is a rigid piece of steel used to keep the chain taught and guide the door arm as it lifts and travels. If there is play in the rail it will cause a whole set of issues. If you’re referring to the carriage guided by the rail, that should have some play in it since there are no roller bearings and it slides during travel. Most of those are generally not adjustable. Hope that helps. Thanks for your question. Have a great day.

[@Captleemo]

Sounds like that door needs some oil on all the hinges.

[@TheMaintenanceMan]

Yes it did.

[@TheMaintenanceMan]

The adjustment screws must have shifted when it tried to open. Adjust the screw for the up position and make a note of how many turns it takes to get it to the correct position. Then back off the down position screw at least the same number of turns to start with. If the door stops short you turned it to far, if it still goes back up turn it more times. Hope that helps.

[@sharontitsworth5845]

What do you do when door hits floor hard?

[@TheMaintenanceMan]

Check to see if you have a broken spring first. If that’s not the issue you need to back off the down travel one eighth of a turn at a time until it closes more gently.

[@orviskid]

I adjusted the nuts on the chain, but only one side of the chain tightens. The other side is still slack because the of gears at each end

[@TheMaintenanceMan]

The reason only one side tightens is because the down pressure isn’t quite right. Back it off 1/16 of a turn. Let me know your results. I’m glad to help.

Sometimes it will leave a 2 inch gap where the door won't shut flush against the top and other times it closes completely. It seems like the trolley stops too early.

Did the main lift spring break? If the motor is dead lifting the door it might fall short or possibly not fully open the door depending on the weight. Otherwise you may have a faulty switch on the upper travel adjustment.

Would you mind helping me out? We replaced a broken motor on a garage door and now it is opening the door too far and the pulley is hitting the bolt at the top. We have tried adjusting the up limit, but it isn't changing anything. Is there something else that we could do to correct this issue?

[@TheMaintenanceMan]

If your upper limit adjustment isn’t working then your issue is with the upper limit adjuster. You should be able to purposely set the limits on a garage door so that it won’t fully open. If you’re adjusting the upper limit and it is not effecting the travel of the door the switch in the upper limit screw assembly is probably bad. Other than the upper limit adjustment there is nothing you can do. The limit adjustment is the only way to correct the issue. Let me know if you have any more questions. I’m happy to help.

[@newsreach]

Thanks for the video. Is there a name for that rectangular metal part that rides along the horizontal bar? It has a rectangular hole in it. My 30-year-old Sears door closer catches it as it raises and lowers the door. I think mine is stuck and won't move along the horizontal bar. I think that's what's causing the horizontal bar to bend when I try to raise and lower the door. The bar has not broken but it may. Thanks.

[@TheMaintenanceMan]

I’ve always referred to that specific part as the trolly. What your describing sounds a lot like a broken spring. Take a look at that next time you get a chance.

[@newsreach]

@@TheMaintenanceMan Yes. The inner trolley. I assume that the spring you're talking about is that big coil (spring) that's about 30 inches long and hangs horizontally above (and parallel to) the door. (That's one part that we amateurs are not supposed to mess with.) I just checked and saw no breaks in that spring.

[@TheMaintenanceMan]

Is the trolley plastic? Has it been greased? There is also a possibility that a roller could be getting caught on the way up or down. One other thing to check is that the cables on the ends are not broken or binding. I’ve seen them slip off one of the pulleys and cause a similar problem.

[@TheMaintenanceMan]

It sounds like the down feed adjustment is set to far. Almost like the door wants to go past the floor before it’s satisfied, meets the resistance of the floor and then re-opens the door. Try backing off the down adjustment until the door actually won’t close all the way then adjust it back down slightly so that it closes just barely.

[@ronald19534]

I have a Craftsman 3/4 hp opener and in the down position/door closed the chain on the left side when you look up is slack a little below the rail. On the right side, when your looking up there is a steel cable which is attached to the chain on the left side. The steel cable is taught on the right while the chain on the left has slack. Is this a normal condition while the door is down and at rest? I looked at the 2 large springs and they don’t appear broken. The door appears to work fine and I replaced all 12 wheels today, 6 on each side, and sprayed the suggested silicone garage lube on hinges and such. I’m just wondering if I need to tighten the chain adjustment where the two nuts and all-thread attach to the chain at the back of the trolley, which I did just a little. I left slack in the chain still I didn’t want to put too much pressure on the sprocket in case you think there’s some other cause for the chain slack at the door rest stage. As the doors starts to open the chain will get tight and complete the cycle to fully open. I haven’t messed with the small circular arrow adjustment screws on the side of the opener. Is the slack in the chain a normal condition when the door is down and closed?.. If it is should I remove the added take-up adjustment which was about two threads on the all thread that I added today. I don’t want to put unnecessary pressure on the motor sprocket if I don’t need to. Your kind opinion and advice would be appreciated. Enjoyed your informative and well done video. Thanks for your time. I will await your response.

[@TheMaintenanceMan]

Thanks for all the details. That helps. From what you described it sounds like your down travel limit is set just slightly lower than the door resting on the floor. That would cause the chain to be under tension on one side when closed. If you reduce the down travel limit a small amount it should stop the motor before it puts pressure on one side of the chain, causing the other side to slack. Let me know if that doesn’t work. Sorry for the late response. Usually I’m on top of things.

[@ronald19534]

@@TheMaintenanceMan Thank you, your reply was right on time. This garage door belongs to a recently widowed friend of mine. Her dear husband lost his battle with Covid. So sad.. I try to help her with her home issues now, we all three had been close for 40 years..Back to the subject, sorry. The up and down pressure adjustment arrows on the side of the motor box I have seen and read about. First, I want to disconnect the trolley by pulling the rope lever while the door is down and see if I am able manually raise the door by hand. If I cannot or it is hard to lift up I think that would be a sign that the upper large tension springs may need a quarter turn or so tightening with the rods I plan on buying at Lowes tomorrow. If I find that I don’t have a problem lifting up the door and the door will stay in place wherever I let it rest, then I believe no adjustment is needed on the tension springs, which I no for an amateur is dangerous, so I’ve read. If I get lucky and I don’t have to mess with the large springs then it would have to be what you suggested. I just thought of the large springs because the door was installed by Sears close to 15 or 20 years ago and I would think after so many years with no inspection or adjustment those springs would gradually lose some of their strength. I don’t know, maybe after proper initial installation they never have to be adjusted. I sprayed them with the silicone lube but even before the spraying they look clean, not rusty, almost brand new looking. A shock to me for being 15 years old or so. Do most people never have to retighten those springs until they snap and break and install new ones, or have you seen situations where when releasing the trolly it was too hard to raise the door by hand and you had to tighten the springs. That’s the purpose of the large springs isn’t it, to assist in raising the door if you don’t have an electrical door opener. After reading this please tell me your latest thoughts. And thank you again for trying to help amateur maintenance mechanics, like myself. Lol

[@TheMaintenanceMan]

Please please please do not try to tighten the springs. You could have a very serious injury or die. Those springs are designed to either last or brake. I’ve not encountered a spring loosing its tension, only breaking. I do like your idea of checking the door with the trolly disconnected. Let me know what you find out.

[@ronald19534]

@@TheMaintenanceMan I didn’t like the idea of an older man like myself on the ladder messing with the springs either. But if I disconnect the trolley and I can’t raise the door up and down like you should be able to what is the cause. I thought that’s what the purpose of the large springs was. I looked good at both springs and they are not broken. Thanks for your kind and quick reply…I’m glad to hear from you that normally people don’t have to tighten the springs. I thought maybe over time they would lose their strength and need to be readjusted. By the way, if I back off the down pressure adjustment screw a little to fix the chain slack, do I also have to back off the up pressure screw at all. How will I be able to tell about the up pressure requirement need…Hope I’m not driving you crazy…thanks for your advice and time.

[@TheMaintenanceMan]

The springs are for the benefit of the motor on the opener. They are not designed to make a door easy for a person to lift. Using your own strength for a gauge of spring tightness is not the best idea. That’s all I was saying about that. As far as the down limit adjustment goes, it is completely independent from the up travel limit. No need to adjust them in tandem.

Yes, your downward travel limit is causing the door to close hard. Back that adjustment screw a fourth of a turn at a time until the door no longer slams and goes back up. Let me know if you run into any issues.

I have a problem on my garage door, I closed and stay close but later open it self, somebody have an idea what's going on?

[@timgeary8228]

I have the same garage door opener (overhead legacy), when the door open there is a lot of slack on left side of chain (facing the door) but not much on right, how do you adjust for that?

[@TheMaintenanceMan]

Is it the opposite situation when the door is closed?

[@timgeary8228]

@@TheMaintenanceMan No when the door is closed both sides are fairly tight. When you open there is a hinge that flows down near the track top and where the chain tightener adjustment is. When that hinge flops down and the door starts to open there is significant slack on the left side. The right side is ok since that is where the emergency pull is and the chain stays on top or near top of track but on left side it drops significantly below the track and has a bow in it

[@TheMaintenanceMan]

If the slack is only there when the door reaches the top of the travel then the top limit is allowing the door to go to far. If the slack is there the entire time the door is traveling either the chain needs tightened or possibly a spring is broken.

[@timgeary8228]

@@TheMaintenanceMan you were correct there was a spring that was broken

[@TheMaintenanceMan]

Glad I could help. I hope you enjoy your weekend.

[@lionelanthony4336]

Have a lot of slack on one side So the slot on the motor will fix? I had a whole new door installed but they didn’t tighten the chain. I have same unit

[@TheMaintenanceMan]

The linkage adjustment on the chain will tighten it. Just a couple of adjustable wrenches and some turns should tighten things up. Let me know if you have any other issues. [e-mail]

[@lionelanthony4336]

It tightens one side only

[@TheMaintenanceMan]

Is it slack on one side when the door is up and slack on the other side when the door is down?

[@lionelanthony4336]

When open slack on one side. When closed slack even on both sides

[@TheMaintenanceMan]

The up adjustment it to far causing slack on one side. Don’t tighten the chain, adjust the travel.

[@marvinprescott9347]

Those damn things are a pain in the tookas!!! ...So convenient when they work but when they don’t, watch out!

[@jaysirivan8582]

How do you adjust the trolley?

[@TheMaintenanceMan]

I’m not sure what you’re asking to be honest. Most adjustments are done to the opener head and chain tension. The “trolley” has no adjustments. Is there another name for the part you’re asking about?

[@leonardtyler3138]

Hey my Garage door Is going up to for The chain is jumping out of the Lil plastic part And slamming back down And it just did that all of a sudden what could be wrong And I have the exact same one that you have in this video

[@TheMaintenanceMan]

Check to see if the springs are broken. Then check to see if the roller track has any obstructions. Let me know.

[@kimberlymarler3114]

What if that rail is bobbing up and down radically and only opening about one foot and then goes back down

[@TheMaintenanceMan]

Maybe a broken spring. Maybe a roller problem. Start there.

[@golfer72rw]

i have a linear opener. Had the springs replaced a month ago and was working fine. it seemes to get out of adjustment. it was going to far open and not closing, about a foot short. i adjusted it for the open part but it wont let me adjust it far enough to close. i took the cover off and it is maxed out. Any advice i would appreciate it.

[@echo1er]

My dad's door won't go up or down. It's seems like it stuck in gear. Every time I try to adjust it only moves in inch

[@linnypsimpson5111]

Broken gear kit on opener or broken spring on door

[@globaltraveler2381]

I accidentally opened my door arm trolley when i disengaged my garage door. Now when i try to re-engage my door the trolley only moves towards the motor. I cannot get it to move in the oposite direction so that i can attempt to reattach the garage door. Any advice on how i can fix this?

[@TheMaintenanceMan]

Sorry for the late response. Once the catch is all the way up try flipping the catch lever on the arm and then raise the door to meet the catch. With the catch lever flipped in the latched position it should “click” into place and the arm catch should grab the catch on the chain. Let me know if it doesn’t work or you need any more help. Have a great night.

[@jturcios8465]

I have this exact garage door opener and I need to know how I can fix a problem I'm having. The problem is when closing the garage door, the door will go all the way down to the concrete but then open right back up. It will not stay closed. Please help.

[@brettgorman3544]

I have the same problem

[@bdmb6364]

+Brett Gorman 1) Make SURE that the Saf-T-Beam senors are working correctly (see page #18-19 of owners manual re: www.overheaddoor.com/garage-door-openers/Documents/DISCONTINUED/legacy-installation.pdf). If they are not working correctly the door will always automatically reopen. 2) if #1 doesn't solve the problem follow the procedures on page #22 of the owner's manual - "Force adjustment". Good luck :-)

[@adamnugent2137]

Awrsome

[@feustond]

I have the same one but I see 2 adjustment screws to turn where u have 1? My door is opening too far and slamming into the light and knocking the safety release out of track and slamming to the ground😭

[@TheMaintenanceMan]

One of your adjustment screws is the high limit or top most point at where the door will stop moving and the other is the lowest or bottom limit. Your top limit adjust is too far that’s why your door is going all the way to the light. There’s also the possibility that the high limit door switch inside is broken so it passes right on by and hits the light.

[@feustond]

@@TheMaintenanceMan awesome thanks for reply.

[@TheMaintenanceMan]

No problem. That’s what I do.

[@feustond]

@Ask The Maintenance Man think I will replace with new belt drive genie.

[@hvnlyangellee]

I need my door to open more. How is that done?

[@TheMaintenanceMan]

You need to locate the up travel adjustment.

[@TheMaintenanceMan]

There will be two small holes on the side of the opener that will adjust the up and down travel settings

[@hvnlyangellee]

Awesome, thanks for your fast response

[@TheMaintenanceMan]

Let me know if you need more information.

[@mandarfineart]

My garage door could be stopped midway with the on off switch but now it can’t be. Just slides down when you press the button to stop. Any idea what’s happening? I did fix a broken mount. Don’t know if I touched something I shouldn’t have. Any idea what’s going on?

[@TheMaintenanceMan]

Is the door still attached to the chain?

[@TheMaintenanceMan]

If it “slides” down that means it’s not attached to the chain to me.

[@TheMaintenanceMan]

Which mount are you referring to? The mount for the opener? Or a door panel mount? Or the track mount?

[@mandarfineart]

Ask The Maintenance Man it’s a screw type not chain type. Yes it’s still attached. So when I press the button it goes up or down but previously I could press the button during motion and stop it mid way. I just can’t now.

[@mandarfineart]

Ask The Maintenance Man it’s the mount on the end of the screw rail connected on top of the garage door. It was broken so I attached it.

[@mecubanodearmas6558]

How come my garage door still dont want to reverse when I put a 2x4 down in the middle of the floor? the door hits the floor slowly and not forcible. but cant get the reverse thingy for child safety. I will really appreciate if someone can help me . Thanks

[@ALLProGarageDoors]

+MeCubano DeArmas you have to locate the "force controls" and turn em down, tell me which model you have and I'll tell you where they are.

[@lylevanasten5420]

My Overhead door , just today, started going all the way down, then it comes back up again and stops. Why won't it stay down?

[@TheMaintenanceMan]

Most likely the travel moved a little and it’s hitting the bottom to firmly. The motion tricks the door into thinking it’s hitting an object before it closes and the internal safety causes it to go back up. Adjust the low limit so that it closes just a bit more shallow and it should take care of your issue.

[@msj103105]

I have the same syrup and garage opener. it will not open all the way. what is the problem

[@clowning76]

just an adjustment

[@clowning76]

turn the knob that says open more. turn it a full circle n try it to see if it made any difference. keep adjusting as need it..

[@msj103105]

I notice on your video the adjustment screws are on either side, both of my screws are on the right side (open) maybe that’s my problem. I was able to adjust the open, then it doesn’t close all they way. When I adjust the close then it won’t open all the way. How do I get the adjustment screws on either side

[@msj103105]

thanks for the response.... I'll continue tomorrow, it beat me up this afternoon

[@esbliss]

I replaced the drive gear and now the door will shut but opens back up after there is a bang up where the motor is the chain almost drops below the track and then reversed to go up. Weird how the chain drops so loose then tightens and reverses the door to up

[@TheMaintenanceMan]

Is the door all the way down when the chain drops?

[@TheMaintenanceMan]

What you’re describing sounds like the limit for the downward travel is set way past the point where the door meets the floor. The motor is stressed trying to press the door further into the ground and goes back up after the stress on the motor gets to high. That would cause the chain to drop on one side while the tendon is high. I’m not sure what the bang is. Possibly the chain is skipping a sprocket due to the tension. Let me know if you have any more questions.

[@esbliss]

Ask The Maintenance Man yes the door is all the way down when the chain drops and then the door goes up. Should I turn the force screws all the way one way or the other to start? I have for two days tried increasing up or down

[@TheMaintenanceMan]

Back off the down control until the door doesn’t go all the way down. Then adjust it till it just barely rests.

[@aljrim]

Overhead Door opener

[@JohnAnderson-kt4mb]

I don’t know what this really is supposed To Solve? The chain will have a tension turnbuckle On it to adjust. Never seen this way befor e

[@joeprince6179]

When you raise the door it jumps then it goes smoothly

[@TheMaintenanceMan]

The “jumping” part has me stumped. Sounds like the door could be stuck, the opener gains tension until it overcomes whatever is holding it and then jumps. Doors are heavy and it would take an incredible amount of force to make one jump even an inch. Have you looked at the springs?

[@sidneymcfadden6337]

My is pulling to the right side when opening it.

[@TheMaintenanceMan]

Maybe the spring on that side is broken. Or the cable.
