How to oil the HVAC fan motor

[@paranoidparanormal376]

i took the blower motor out of a old trailer and its from 1974 i washed it with water hose waited for it to dry then oiled it wired it up to a exstenion cord and now its a great shop fan the best shop fan iv ever owned

[@mdwillington9416]

I do the same with box fans, electrical engineering is not a strong suit at our local college, they must have mommy and daddy’s money because they throw them out if they get a bit dirty 🤷‍♂️

[@JRNipper]

Just replaced the outside fan motor in our home HVAC system from 1978, it was the EXACT same Emerson motor in your video and was the original motor. It was still working, but the bearings were starting to get noisy. I kept it oiled the 20 years we've owned this house along with the indoor blower motor which is still running just fine. The system is a Whirlpool "green wedge" HVAC system and I've never had to call anyone to service it. I keep the motors oiled and replace the caps and relays every 7 to 8 years. No electronics to worry about, and we're still using the original White-Rodgers thermostat. The system gets a good workout here in FL and I'm not replacing it, not ever. Any part that goes out that I can't replace I'll just have a serviceman do it and if the R22 gets out, I'll use AC77.

[@dzignrtastz1111]

I about had a heart attack when the blower motor in my 24-year old Interthem/Nordyne started intermittently screeching this morning while getting ready for work, and after stressing quite a bit over the course of the day followed by some clean up and your video this evening, I quickly and easily found the aluminum oil hole plugs and managed to throw a little Zoom Spout (I actually had a bottle lying around - LOL) in each... without even pulling the blower. Major props for helping yet ANOTHER (quite thankful) DIY'er. ;)

This fan works very well. kzbin.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh I replaced my old fan as our radon levels began to spike. When I remove the old fan water poured out of the fan. Must have entered in through the out spout. Replaced with this unit and levels dropped a bit but still over 4.0.Did some more digging and found that we had a small hole under our waste pipe that was allowing some water and radon in.Patched the hole and the levels dropped almost overnight.I really would recommend the radon sensor. It gives real time readings. Without it we would have never known that we had this issue.

[@grayfurnaceman]

Most motors do not have them anymore. However, we work on things that are not new. So its good to know what to look for. Thanks for the comment. GFM

[@girlmastergeneral]

what about an 06 blower? think it would have them or not? I'm getting a quick squeal from the air handler when it turns on.

[@veroniquemartin5807]

Thanks Gary, you were very helpful to jump start me troubleshooting. Yes it is an old furnace. About a week ago, an electrical type of burning smell came up to the 2nd floor bedroom, late at night. Got worry about a fire. Went to the basement first to check the furnace. Could not smell burning, but heard an electrical humming and buzzing before the fan kicked in. Outside belt drive motor, no capacitor. The best is that I got a brand new motor, same specs on Easter Sunday.Owner of “James Electric & Motors” said I am open 24/7 and 365 days. Got motor and put new. Works like a charm! No more smell, humming and buzzing. No more erratic start and stop. Nice and quiet now. When I pulled the old motor out and open the flap, i noticed a loose white plastic electrical connector plate. The motor shaft still turns easily. I do not see burn marks or smell any burning.Last time the blower motor went, I paid $80 CDN parts and Labour. That was 18 years ago!The motor was $140 all in. USA

[@grayfurnaceman]

Glad you got it going. GFM

[@solarsynapse]

If the motor is sealed without oilers you can open it up and add tubes. I cut a notch in the metal caps and a notch in the housing in line with a vent hole with a Dremel (Be careful not to damage the coils! Don't get grindings in the bearings! ) and added plastic tubing (Ice maker water line?) to the hole in the outer bushing. While you are at it you could clean and polish the shaft and bushing if you think it needs it. Be sure the goo wick is not impacted in the hole. If so, clean it out and add some of the fresher surrounding goo or leave it out and push the tube in up to but NOT touching the shaft. I also added 1" of lantern wick cut down the middle and inserted in the end of the tubes at the bearing end. I used appropriate machine screws slipped into the outside ends for caps. So far so good. Not something that everyone would try but I am cheap and tenacious and did not want to throw away a good motor. If you try this, you may want another motor on hand or have fast access to one. I occasionally turn the furnace off and check that the cage still spins free and then turn it back on. BTW Marvel Mystery Oil barely lasted a day oiling without tubes or wicking. Hoppes gun oil lasted over a week oiling without tubes or wicking. Briggs & Stratton oil which is detergent straight 30 seems to work well. The non detergent Zoom oil is probably best. I cleaned and removed the previous oil before trying each. Yeah, I like to experiment too. ;)

It'd be great if you made a video of this method.

[@andycensus]

Great video -- When I pull out the blower assembly - I'll also take out the fan motor (from the blower assembly) - then clean the blower wheel, assembly, and motor. Perfect time and it only takes 10-15 min and this greatly improves the blower efficiency.

[@breid1966]

Thanks for the help! After coming home from picking up my wife after she hit a deer and it tore up her car really good, we smelled something burning in the house. The 1st thing I thought of was the furnace. Sure enough, the blower wasn't turning. I cut the power immediately. After cleaning the deer (I DO have my priorities - lol), I tackled the blower motor but could not remember where to oil it or if it was sealed. I have replaced several of these but it's been a while. Again, thanks for the simple reminder!

[@SoCalUSN]

Those darn plastic plugs like to sneak away when you aren't looking. A #8x1/4" or so pan head machine or sheet metal screw makes a good replacement. Thanks for taking the time to make a great video.

[@smjones4238]

I have several ZoomSpouts, they have basically 10 wt oil in them when new. I have a new one, one with 20w50, & one with 90% 30wt & 10% STP. Various ages of motors use different viscosity of oil to protect them for long periods. Just me, maybe, but I service a lot of older stuff, and it hangs in there fine, if taken care of. Michael in Colorado.

[@Pureblood1776]

Well this just saved me hundreds if not thousands depending on the technician. Thank you brother!

[@Stowneyo]

I loved this. "Should oil everything under the sun". Guess that'll do. I was at the lasses house and she was complaining that's her heater was squeaking like mad. And I just said it needs some 3-1. But then I looked at the thing and needed some help navigating . Thanks for the laugh along the way my friend

[@2210tkm]

*Well-made, delivered quickly, and easy to install with **Fastly.Cool** . I may be imagining it, but it seems quieter than the 14 year-old unit that I pulled out. Of course it was noisy at the end due to failed bearings, so hard to compare. :)*

[@altruistkun]

Thank you! This really helped me. I had no idea where the oil holes were, the manual for the McQuay HiLine says to oil it every 6 months, but it doesn't say where!

[@5hogg23]

You just saved me so much time and money. I had a bearing in the heater fan for my house starting to make noise tonight, at the beginning of a snowstorm and several days of below freezing temperatures. A few squirts of oil and it hasn't made a peep in several cycles. I am at least able to put off the actual repair until a convenient time and won't have to find a new motor in the ice storm. Thanks!

[@olavcramer8601]

Thanks a lot. I just did this and the fan's blowing again. Wouldn't have know to look for the back cap. On my 80's era Carrier the front cap is just an indent in the motor housing, but it did the trick I don't have your cool oiler, but found a little bit of heat from a torch allowed a typical WD40 can straw to easily bend to perform the same duty. Cheers to you!

Welcome GFM

[@bobsquires4521]

Thanks for the clear video - couldn't have been easier, the caps were missing and directly on top of the unit. Filled with 3+1 for now - see if the noise is gone when my cleaner-guy comes to fix the burner that's kaput for a month now. That's usually an easy fix and hopefully I'm back in the heat again tomorrow, I'll report then on UP/Down status. Many thanks.

[@solarsynapse]

I think the felt/Permawick sawdust looking goop inside is an oil wick and not a filter. If dust builds up from leaving the cap off (years), it will clog the wick and stop it from oiling the shaft. A clear flexible tube to the front bearing is a good idea so you may not need to remove the blower. I blower cage should spin for 10 seconds or more after the motor shuts off to insure free movement. It is said to not use a detergent oil since it is not an internal combustion engine. The oil you are using I think is the "standard" "turbine" oil. Do not over oil or it will leak into the coils.

[@richardesposito6622]

Thank You so much! Can only can get to bottom of the our 30 year old goodman attic unit! Did this a few years ago along with a bit of cleaning. It really did help and the fan turned faster. Not fun to work on.. Hands just to big to fit up to the top mtr. oil vent!

Thanks for the update on oiling my reducer blower. I was thinking the same thing at first but having troubles exactly on where to oil it.

[@slip0n0fall]

This along with a push-start (using something plastic/wooden) can sometimes make the difference between a 90* house before a tech can make it out to replace the blower and sitting comfortably while waiting.

Good video mate .... question : Old motor from church went out ... I got a diferent one .

Com wire is left .... maybe thats the issue ? ... thank you

[@TroyTube]

I recently had to replace the capacitor on the blower motor. Afterward we noticed the blower sort of rumbling. I thought the blower cage might be the culprit after all the things I read about fins coming loose and dirt falling off which causes it to be out of balance. I even realized on the way home yesterday the blower sounds very much like the tires on my Tahoe that are out of balance. After all my research, I decided to take a look at it. I could determine nothing about the blower cage other than I can tell it's out of round a bit when I manually spin it slowly. I do see one weight on a fin, and there does not appear to be any missing weights or loose fins. I removed the blower and cleaned it thoroughly. There might be some difference but it's not much. The motor seems to turn smoothly and there do not appear to be oil holes. However, the shaft on the motor has a bit of play in it. I'd say I can move the shaft in and out about 1/8". Is this normal? Is this likely my problem or should I still look towards the blower cage? The shaft does not appear to have any wobble and otherwise turns smoothly. Thanks in advance!

[@grayfurnaceman]

+TroyTube The end play is normal. Blowers can come apart where the hub is in contact with the blades. Its not very obvious but there should be some paint missing at the contact point. Also, the set screw portion of the hub can break loose from the rest of the hub. Other than that, the blower could be cavitating. Usually this only happens when the blower door is off. Hope thus helps. GFM

[@TroyTube]

It must be the motor that's the issue. I replace the blower wheel and it sounds exactly the same. Sort of a rumble that is every second or so.

[@GrifFungin]

TroyTube Did you ever fix this issue? One of my rentals has the exact same issue. It’s a rumble every few seconds. I see nothing wrong with the motor or the blower wheel. I get the same sound with the door on or off the airhandler....

[@facesmasher4216]

GrifFungin - i would probably dissaseble it and try manually to lube it if theres no oil port, make one, then put a plug in it or at least some toyota silicone, let it dry and try it again good luck

[@MultiHvacr]

Most of +10 ton packages units with belt driven blowers you have to use a grease pump to lubricate the bearings.

[@mrbob55304]

Superb camera work! With tripod! Sweet!

[@grayfurnaceman]

Well, nothing at all. If the bearings are sealed, there is a packing of oil around the bearing meant to last the life of the motor. If a seal fails and the oil runs out, the motor must be replaced. Most motors now are sealed. Thanks for the comment. GFM

[@Droneflyers]

You actually can oil the motors that are sealed - some vids showing how but I just did mine and made a quicky - windings and armature and shafts were perfect, it was only oil that it needed (I replaced mine later anyway, but didn't need to) - kzbin.info/www/bejne/jJjadImEetaohMk

We've had this issue for a week; does it off and on and not all day. I've told the landlord about it twice and even sent an mp3 file with the noise to drive the point home. I might just oil it myself. I'm not a homeowner or home renter, but rent a room in a house with 3 other guys. Landlord has been flaky lately so I'm not sure I want to live hear after my year lease is up next august. The main issue is that when it happens I can hear it through my bedroom walls and it is hard to sleep, the neighbors for sure can hear it too since it's close to their house.

sorry if u already addressed this but do u know if I can swap out a belt drive blower for a direct drive? my old belt drive unit has gotten a bit too noisy & I'm hoping I can quiet it a bit. i believe the noise that bothers us is caused by the shaking of the elements due to the rough motor movement.

I have a Dayton fan motor running my whole house fan. I've never oiled it, so based on this video, I went up and looked at the motor itself. I found 2 yellow plugs that look right, but they are facing sideways from the motor housing (the motor is mounted such that the shaft points down). The motor housing says "Lubricate with 30 drops once per year". First of all, how do I measure 30 drops when the holes are sideways? Do I need to unbolt the motor and turn it hole-up? Also, I presume 30 drops per hole, not 15 each.

Where is the capacitor on the old furnaces? Or is there one at all?

Some very old furnaces, especially with a belt drive blower may nit use a capacitor. GFM

[@asdfgoogle]

How about a draft inducer motor? Do they typically have oil points at well? I looked on mine and I didn't see any. The problem is that the furnace only SOMETIMES engages. The thermostat clicks on just fine, but that often just leads to a buzzing/humming noise from the furnace. On times that the furnace does decide to work, the blower motor will kick on and shortly after, everything else will start doing it's job.

[@grayfurnaceman]

+asdfgoogle Most of them do not have oilers. If the rotor of the motor is stiff, the bearings have failed and it must be replaced. You can oil the shaft near the bearings. That may help for a while, but the bearings have failed. GFM

I was reading the manual with my Rheem highboy furnace. The manufacture states SAE 10 or 20 motor oil or light oil for blowers may be used. In addition to that information the manufacturer states only to add between 10 - 20 drops of oil every 2 years of regular service. or every 5 years of light service. more oil than that can damage the motor. Check manual as it should be with the unit or call the manufacture.

Generally, I recommend replacing the cap with the motor. Also, the new motor may use a different size. As for whether the cap was at fault for the original failure, or even if the original motor was failing, I don't know. These motors can operate at 40 degrees Celsius above ambient(about 170 F).

[@SHAFTMOSLEY]

it should ignite before the blower comes on.

[@grayfurnaceman]

Your gas must be turned on for the blower to work unless the thermostat has a "fan on, auto" switch. You can test the fan there. You have power to the furnace because you hear the click. Turn on the gas and go thru the same steps. Depending on the age of the furnace, it will either fire up on its own, or you will have to light the pilot. Hope this helps. GFM

Most motors made in the last 30 years do not. GFM

[@quezlark7875]

Just fyi a lot/most of the new motors in modern residential hvac units do not have these ports. 9 times out of 10 if your motor starts to screech you can delay the inevitable but you will most likely need to replace the motor.

[@grayfurnaceman]

You are correct. Of course you can't oil a motor with no oilers. But you have to look to determine. GFM

I let it cool down and it came back on but need to oil it I think

[@matvangogh]

we just had a HVAC guy telling us the motor was dying and it was a little stiff- causing it to stop working after an hour. but when it cools down it may turn on again. Are you saying that all you need to keep it up and running is lube it?I think ie caused the capacitor to stop working. The HVAC guy says these motors are destined to fail after a certain number of years( less than 10) since they are on continuously nearly the entire year. Is he right or was he just selling us a car here? its an Tran xR80

[@grayfurnaceman]

Sounds like the bearings have failed. As for the longevity of the motor, many motors last for 20+ years. GFM

No need to remove old oil?

[@grayfurnaceman]

No GFM

[@solarsynapse]

Update. Still running. I have been adding 5 drops of the Briggs oil to each tube every few days. Time varies with outside temp and amount of use. I noted a range of 10 to 40 seconds of spin after shutoff. I am shooting for mid twenties. I really wish I could buy some new Permawick goo. Anybody have a source? Anybody work at a motor factory?

[@private1572]

How often should I do this?

[@grayfurnaceman]

Once a year. GFM

[@METAL_CHICK]

IF NOT REPLACING CAP.. CAN IT MAKE WHEEL TO MOVE AND FALL OFF????

[@grayfurnaceman]

If you have replaced the motor and not the cap, If the cap is the right size and the cap works, the wheel will rotate. GFM

[@METAL_CHICK]

@@grayfurnaceman THANK YOU!!

[@davemarm]

You mentioned the "infamous zoom spout oiler"? However it appears that you use it anyways. Why "infamous", is there something wrong with it that we should be aware of?

[@masonlovesroblox]

Most people are unaware that the word “infamous” is derogatory and actually means “well known for some bad quality or deed.”

[@grayfurnaceman]

Thanks for the support GFM

[@adrianquinonez6667]

weird my landlords swap cooler motor doesnt have a place to put the oil in? its one of those that are mountied on top of the roof. iv lubed the sides but there is nothing for the motot

[@grayfurnaceman]

Many of the motors are permanently lubricated. GFM

[@muniznick]

I usually loose the zoom spout oilers cap on its first use

[@grayfurnaceman]

Me too. GFM

[@fisherbrown903]

[@grayfurnaceman]

At this point it may not make much difference. And yes they are hard to oil. Sometimes even have to remove the motor. GFM

@@grayfurnaceman how long can a furnace last. Or. Heat. Exchange I live in nj

[@grayfurnaceman]

Good video !!!! Can I used 3 and 1 to oil my blower motor ?

[@grayfurnaceman]

Its probably as good as anything. Go for it. GFM

[@markfothebeast]

+grayfurnaceman Agreed. That was my first thought when I saw this video.

[@jimw7550]

Use 20 wt motor oil.

[@10minutesounds31]

Will 3 in 1 oil work?

[@grayfurnaceman]

Yes GFM

[@user-ju3od5gy5q]

Thank you sir for this video. My fan blower motor seems a little louder than normal when it turns on. Will try oiling.

[@328Jayd]

Manuals ive seen recommend 10 drops every 6 to 12 months. You can extend the inside port with a small piece of brass tubing and gas trimer fuel line. switched to IngersolRand recriprocating air compressor synthetic all season oil. If the motor is covered with dust you need to clean it with a vacum.
