How to set the travel limits/force on LiftMaster models 3850/3800

[@jamesrodgers1074]

Electricity was out for Hurricane, back on line, one of my doors didn't work. LED indicator light was blinking 11 times. Finally found a key that showed what 11 flashes means - max force down. Remedy recommended was to reset limits and forces. Your video was fantastic!! Thanks so much.

I'm real glad I found your video. This fixed my issue. I looked at all the moving parts and felt it may be an adjustment that was needed. I'm not sure why my garage door opener lost it's mind, but I'm glad that's all it was. Thanks for taking the time to post this fix!

[@bradysgaragedoors]

Glad it helped

[@kochieh1477]

A video is worth a thousand pages of instructions. I messed up the travel during MyQ video keypad setup and this should get it back to normal. Thanks

[@user-ic7oh2xe5n]

Your video is better than all of the instructions posts I’ve seen you are great

[@tvkid84]

You just saved me so much money! Thank you!!

[@ericpowell7547]

Bravo!!! I got it!!! A note; our back up battery is dead, and the electric went out. The doors travel boundaries were erased. It kept trying to go down from the closed position. Thank you!!! GOD BLESS!!!

[@miketran3357]

You just saved me $125 bucks - that's what the repairman charged me last time this happened to my garage door. Thank for this awesome psa video. 👏 👍🙏

[@MrSpuzzz]

Thank you! Have an electric car that I park outside and needed a small gap to avoid crushing the cord. Your tutorial saved the day

[@ericpowell7547]

Your video is my go to, and you saved the day again!!! 3rd time!!! When the electricity goes out, so does the memory of the door adjustments. Thanks again and again!

[@bradysgaragedoors]

No problem thanks for watching

[@VelociRabbit1]

You are amazing at audio and video both. A lot of people talk when they don’t show what they’re actually pressing or fiddling with. You’re awesome at this, and should keep on going!

[@lyndongp]

Thank you for your video! I was able to fixed my garage door that won’t open after power outage!

[@_moes_garage_]

Thanks a million! My power went out and then I couldn't open my door. Resetting the open & closed position did the trick.

Awesome step by step. Straight to the point. Works for the Chamberlain HD900D (same company as lift master) as well.

[@fortheloveoftheocean5400]

Awesome thank you soooo much!!!

[@TBHD724]

If I were you I'd have someone out to take a look at that center coupler. It looks like it's starting to pull apart and the torsion tube is flexing some

[@fourdoormafia]

Thanks for the video. Works great on chamberlain heads

THANK YOUUUU

[@tritran8582]

Thanks

[@joannewu6394]

u should get a bigger rail bc the carriage is about to hit the motor unit. btw an 8587 will be better for that door

[@bradysgaragedoors]

A longer rail won’t fit, there’s a beam in the middle of the garage. Also an 8587 would be good if the door was unbalanced, and bigger, but in this case it’s not necessary. Also, this opener is converted to a chain drive for better strength.

[@elmergaviola7241]

If you don’t have a remote can you use the wired garage door button as a substitute to accomplish this adjustment?

[@bradysgaragedoors]

Yes you can.

[@larryg4662]

My purple or black buttons wont stop or start the door.

[@raturishikha]

Seems you are a pro at this, do you know how to connect it with myQ ? I tried the learn purple button but should hear one beep but it don’t hear any beep.

[@bradysgaragedoors]

Thanks for the comment! These units are actually not MyQ compatible. If you wat the MyQ you need to buy a MyQ hub.

[@Russell_L365]

When I press the black button to program the open position, the door only moves an inch or so and stops. I have to repeatedly press the button a hundred times to get the door in the correct position. When I'm done and click the remote, the door only moves an inch or so.

[@bradysgaragedoors]

Could be a bad logic board on the opener

[@Russell_L365]

@@bradysgaragedoors Thank you for your reply. I was thinking it could be that or the travel module. edit: I just unplugged the travel module and now the door opens ~10 inches before it stops and the lights flash 10 times.

[@maxnovo625]

This happens to me as well. Did you ever figure this out?

[@Russell_L365]

@@maxnovo625 I replaced the logic board.

[@maxnovo625]

@@Russell_L365 In my case the 4 white plastic motor clips that engage the positioning sensor broke off the motor. Which means buying a whole new motor.
