- This video is about how to replace a broken or burned-out blower motor in your air conditioner/furnace HVAC unit. Blower motors on amazon→ amzn.to/2wWNI38
When you replace the motor, also change the capacitor→ amzn.to/2f0VAe1
Just be sure to get a capacitor with matching 'uF' and 'V' values.
This AC was making a lot of noise before it broke. If it damaged your blower wheel you will want to get a new one because it will be out of balance.

One of the best how-to videos I've ever watched. You do an excellent job explaining things while not rambling on and on. Thanks for the help.
I followed your advice, after I had ordered a new motor, and also bought a capacitor. $3.80 online. change it while the whole assembly is out. HVAC guy wanted $750 to replace blower and another $250 to clean the squirrel cage. Thank you.
$1,000 for that job you better never ever hire that HVAC guy he's ripping too many people off
Excellent video - my A/C company wanted $2,000 to do exactly this (replace blower motor and capacitor) and another $600 to clean the blower wheel. My equipment was running fine but the seals were starting to leak and you could see some oil residue on the motor. I'm gonna replace these myself - the motor is $160 and the capacitor is another $12. Your video really helps - thanks!
Thank you for getting me started on fixing this problem! It turned out that all I had to do was replace a $9 thermistor but you got me started diagnosing the problem. Thanks!
Yep cleaned my cage and it went way out of balance... had to take 3rd trip to store and buy a new one... In the future if I have to do it again I would just buy new motor, cap and cage all at once. But non of the videos told me that except this one witch I watched AFTER! Nice video.
I found this humerus lol. The thermostat tech talk had me on the floor. Fan on or auto the Air Conditioning systems not coming on unless you switch over to Air Conditioning. Never the less just turn off power at furnace or breaker and remove blower motor. Check size and get appropriate size capacitor. When the blower motor is set secure the hub bolt to the shaft. There's no off center when the legs off the bellyband are set. Just the cage being set and secured at the hub that you failed to do. 40 years in the trade myself and I do get a kick out of these videos. Thanks for making my day lol
Coming from an HVAC tech.. Nice job
Very nicely done. It helped me understand how to do it and even ended with an issue with an unbalanced blower and what needs to be done to correct it.
Great video man,very clear and you explain everything in detail, Ive done this many times but i like to also watch others do it
Lol same
Adam- thanks for the video. I try to do as much DIY as I can. Nothing in my HVAC will turn on right now and why wife heard a big clank, which makes me think the mounting points broke. I figured I would need to call an HVAC guy, but since I want to DIY everything I started looking into how to do this. Like everything else, it’s not has hard as I thought. Thanks!
Used your video to guide my repair. Our unit was making an obnoxious squeak that started about 2 weeks ago. I suspect it was a build of dirt on the fan blades that caused a balance issue. This drove the whole assembly to resonate at speed. After a good cleaning and inspection, it seems to be nice and quiet now. I'm no HVAC guy but we do change our filters regularly. I was surprised by the amount of crud that still built up on the motor and fan blades. Probably good measure to clean every couple years. Especially if one constantly runs the fan (like we do) for air circulation. Should extend its life.
Great video Adam. Specially the suggestions to take photos of the wiring. I would also add to take photos of the motor schematics on the original and new motor. I got my new blower motor in and fully installed and the colors on the new PSC motor were completely different colors. I had to start over.
Excellent video. You should be a HVAC instructor. Very well explained. Thanks
Thank you very much really useful video , Thanks also to technology which makes sharing knowledge easy like this
Your wobble is due to the rubber bushings not the squirrel cage I think. They are allowing for to much movement of the motor.
Great thanks. I can't believe the contractor wanted to charge me $832. That is as easy to do as an alternator. Now I have no fear. Thanks again.
John Archuleta Wow thats a serious chunk of change!
John Archuleta You called the contractor , right ? What did you expect ? You getting money and getting your repair done too ?
It cost me $650 which includes $150 for the blower motor. My guy also recharged the R22, which is a real expensive refrigerant. He had to climb up in the attic of my office building and do it in the Heat of the summer. It was well worth it to me.
One piece of advice for yourself and those watching would be to NOT put the lock washer between the bolt head and rubber bushing surface. Better on the other side, where there is the housing's metal surface and the nut. The purpose of the lock washer is to keep the nut from vibrating loose. Also better would be to place a flat washer between the bolt head and rubber bushing surface.
Thank you for the video. I had to replace my fan wheel and you showed me exactly how to do it. Saved me a lot of money. Thanks again Bro!!
Thanks for video. Though I can't help but wonder if after market mount with the "rubber bushings" was part of the problem causing it to be "out of balance". I think you needed a more firm mount that affixed the motor firmly to the housing. One would think the rubber would help soften any rattle or vibration, but in reality it could have provided too much give....just a guess.
L Dlink This is exactly right. It’s the new mounts not the wheel. The rubber bushings are allowing the motor to shake and oscillate.
Just did mine and it works! Your video helped me gain the confidence I needed. Thanks!
Thanks for this tutorial! I replaced my Bryant blower motor per your video and all is well!
BRO! YOU'RE DOING ALL OF US A FAVOR! THANK YOU FOC THE INFORMATION!
Good video! Im about to check my blower fan and motor because of an intermittent grinding. This was very helpful in getting me ready to work
Great job!!! You are a wonderful and patient instructor!
I wish I had more opportunities to change motors in my socks. LOL great VID. thank you.
you were right I replacd..the blower motor capiciter and cleaned out the coils..on the outside unit...so far so good...thanks for the insight..and helping me ...with all my quistions....jesus loves you god bless
That's great news David. Good work!
That's a crap load of thread locker. Good video
Very good video. I wish that I could watch your "other video" about replacing the squirrel cage. I don't see it in your list of videos. Di you make another one? I have the problem with my A/C where it sounds like it is rattling excessively in the squirrel cage: I am guessing. I am just working through the steps of learning how to do this. So expensive to hire people to do it, so I have to learn how to do a lot of this stuff myself. You make it look easy and give me the confidence. THANKS!!!
Thank you for a informative video upload. I do have a question. at the end it was vibrating a lot because you said the blower wheel was not aligned. did you change the blower wheel ? did it quit vibrating ? I am facing the same problem after replacing the motor ( not OEM ) vibrates too much and it can be heard in the bedroom. The unit is in the attic.
Did you figure it out? I was just inspecting mine and it's doing the same thing
Thank you very much! This video was a huge help. I appreciate your time!
Very good clip
Learned a lot from it, good instructions
Great .
I have a Bryant plus 80t furnace + AC in my house. It was installed in 2003 and I have the original furnace company that installed it as my maintenance company. They come out 2x a year and so far, the system works perfectly. For repairs, I have had the furnace capacitor changed 2x and the AC capacitor changed 1x. For the yearly cost of my gold membership ($20.00 per month) and small maintenance repairs, it is much cheaper than an entire system.
Well done! repaired mine today *fingers crossed
Hello Adam, this is the video that wins my subscription! Thank you for this great tutorial.
Question> Where is the link for the how to alignment the blower? Thank you
Good video! How hard was it to remove everything to replace the blower wheel since you used Red Locktite on so many of the screws?
Blue Loctite would be fine in this case as red is more then why he needed
Thanks for the simple video. Guess what I'm doing Saturday.
Thanks for the video. Good Brother............👍
thanks for the video! I replaced my brackets too but kept the same motor.
when I put it all back together I made sure the fan had equal clearance on both sides. I ran it for 30 secs and it locked up again
I removed the assembly and noticed the shaft had a 1/2" of play. Is it normal for you to be able slide that shaft back and forth in the motor casing?
+cjstrick2010 No it should not move around.
Thanks for this video, which helped a lot. I was not able to pull out the motor from the blower fan. I looked at another video, which showed that one needs a specific puller tool to separate the motor assembly from the blower fan. Has anyone experience this?
Yup, qualified havc techs have those tools on their vans and know how to use them. I suggest calling one and having the repair done properly.
Thank you Adam for posting such a good video. I've never worked on a furnace before but you gave me the confidence to give it a try!. My furnace blower motor went out last week and I removed the motor and housing and bench tested the motor as you described on another video. I have another motor on its way but I have a question about the capacitor . I found one online that is similar to mine ( 15 uf 370 v 50/60 hz 70C) . Is there anything else I need to know before I order the capacitor? Also, when I install the capacitor, do I need to short it out first , before I handle it?
Hi David. The uF and V are the values you need to match, don't worry about the other specs. You can short the old one to be safe, the new one will not come with a charge so don't worry about shorting it. Best of luck!
David put your tongue across it to short it out, that is the Diy way of doing things.
Excellent video, good info, thanks! Saved me a lot of money!
Awesome! I'm glad to hear it.
Dude! Did you test your new capacitor? I just got back from Grainger with a brand new 7.5x370 capacitor and it tested 0 on my multimeter. I installed it anyway with the same results (severe buzzing) as the old one. I'm on my way to exchange it but I'll bring my meter this time.
Ok I have exactly the same unit. But the part number for the blower wheel is gone. Do you know the part number for that blower wheel. Mine measures 1foot diameter and 1foot tall. It looks exactly like the one in the video.
I lost track which one goes where on the capacitor they both the same color and same connection type. Does it matter what side? My capacitor has only 2 sides but has 4 prong per side. Your help will be appreciated!!!
Well detailed video, thank you very much
I have no second switches to turn off. mine just has a push in switch that you pish into apply power , which mine is sticking out, if it is sticking out will that be power off?
Excellent description! Thanks
great thank you . now i know how change my motor. again thank's
What if that red led light goes of a second after you push in the button?
Surprised 3 mounts lined up without drilling new ones.
did you have wire up the new motor or did the motor come pre wired for install
Thank you this video was a big help
My furnace doesn't have any room for me to take out the blower. Have you seen something like this before? Thank you.
The bolt is called set screw
Awesome, fixed my issue thank you.
I have the same unit and the blower stopped working. What is the model number of the blower and how much does it go for?
Sweet thanks. About to do mine
Nicely done. Nice touch with the redlock.
This video was so dang good. Could you list where you got the alternative motor mount w/ rubber grommets?
Nice video. Does air pull from both sides of the housing or just from the open side?
Great video Adam. thanks a lot!!!
My home aircon is not blowing any air and the technician says it will cost $600 for the motor itself plus labor and service call, do you know if its that costly?
Last year Vendor charged me 2000$ for installing a new evaporator coil so dont want to get duped again.
Vishwas Bodani $2000 for an evaporator coil replacement isn't a bad price at all. $600 plus labor for a motor replacement is high. Keep in mind that these are two very different repairs. I do this for a living.
Very Informative Video !
Excellent video, thanks
Great video, thanks for sharing
I noticed there was an extra fan speed wire (yellow). Should that be taped off with electrical tape or attach it to "spare 2"?
+Jason Nhan Just attach it to Spare. Those connections don't connect electrically to anything, they just allow you to "park" the motor wires you don't need. There are multiple wires, one for each speed the motor can run at. Often White is the common wire, then Red, Blue, Yellow, and Black, in that order, for slower to faster. AC will generally take the highest fan speed (Black) and heat takes one of the others, but generally heat uses a lower speeds like Red, possibly Blue. Heat works better on slower speeds.

Where did (specifically) did you get the new motor? Was the generic mount bracket additional or did it come with the motor? Roughly how much was the motor and bracket?
It's been 4 years now so I can't recall specifics but it was purchased from amazon for around $90 and it did come with the bracket.
Blower capacitors a run or start capacitors?
Looks like your replacement motor was reversible (the short looped wires). One needs to make sure you have the fan rotating the correct way with this reversible motors.
Thank you so.much....but my i have a question i hear some whistle when my heat is on.....what it is?....but it no coming from the furnace...what is it...please help?
It depends on where it is coming from. You have a lot of air moving so a whistle can come from something loose or out of place. Does it do it if you just run the fan?
Where can you get the motor from? Also is there a special tool to to remove the mower?
I order a lot of parts from Repair Clinic. Com
now I came to see if blower motor was working I turned off the switch next to blower motor and gas line.....and then I turned it back on now it's not doing nothing did I podsible..kill the furnace flame
I got a call, that they had two Winters with very low Airflow. The H.O. had replaced the motor himself. He turned the fan around, because the Hex Screws were hard to get too. He didn’t know you needed a long Hex key and to reach through the fan blades to turn the Hex screws. He cut the shaft on the old motor, to get to the Hex screw. Needless to say, he needed a new a Furnace, the heat exchanger was cracked on every cell.

Blue Loctite would have been bad the red is overkill
You rock. Thanks for posting this.
No problem!
Very helpful. Thanks
My furnace is like 20 yrs old how hard will it be to find a replacement motor? Thanks!
I would replace the unit of I were you 20 years is about the lifespan of a gas furnace
I spoke too soon..lol I guess my last step is to clean the A coil..in the furnace. ..that could be the only reason for my suction line to freeze up and cause my blower to stop blowing any air
Great Video saved me some hard earned moola.
So my unit does the same thing except in my case if I turn the unit of for 4 or 5 hours it'll start working again for few hours. Would that be a motor or the capacitor guys? And where would I find these parts beside online?
Sounds low on charge, go to auto zone and buy some cans of R-134A, then try to figure out how to get it into your A/C system, lol.
Outstanding!!!!!!!!!!!!!
Blower is making loud noise. Any idea what cause it?
It may have a broken mount or it may be loose on the shaft or it may be out of balance. Can you see it spin? It should not have any wobble.
thanks i need to do mine,
The motor won't pull from the housing on my unit. Devin screwed all the same exact bolts that you said and it will not pull from the fan . Any ideas or reasons why this is?
My first guess would be that a bit of the metal lip it is hanging from is pinching it or holding it back. Try to shove something under it to help take off some of the weight. Can you shift it at all?
A hvac professional would have the skill, knowledge and the proper tools to know how to separate the blower motor from the wheel. Why didn't you call one in the first place?
HVAC pros use what's called: a fan puller.
You can be purchase them on Amazon or eBay.
Easy peasy lemon squeazy, polishtheturd mickelson.
Witch led....we're is it at
I Have That same HVAC
Looks like a blower motor for a car HVAC except it's bigger did not know those looked like that for a home HVAC
Heat Pump
the shaft wont come out of my blower wheel what do i do
Patty, heat it up with fire. That should help get it off. Or call someone with mechanical skills like a hvac contractor to repair the issue.
Good Job, thanks for the video.
1:58 I heard a wierd noise when u let go of the button
Before you start taking it apart turn the breaker so u don’t get Shocked
THIS DID NOT FIX MY WARM A/C FAN, HOW DO I FIX IT??? GOOGLE HOW TO FIX A WARM A/C FAN, HOW TO SEARCH GOOGLE GOOGLE GOOGLE HOW TO DELETE COMMENT, MY ELECTRICITY CAPACITER IS NOT THE PROBLEM EITHER!!! TOLD ME TO TURN POWER OFF TOO LATE, I GOT THE SHOCK OF MY LIFE!!! Couldn't find fan label, must've burnt off, how do fix? (EDIT) Problem fixed!! Used box fan as substitute!!! THANKS ((EDIT 2)NOT FIXED) DIDN'T TAKE PICTURE OF MOTHERBOARDS.
Why do I have a transformer instead of a capacitor ???? :{
When I turn my heat on it smell like metal. All my research lead me to believe it's the motor that need replace. If I still follow your step or should I just call a professional to do the job?
It just depends on your specific skill level. Also if I had the money, I would not fix anything myself but just pay someone else to do it! It just depends on your specific situation.
Junior, call a professional, If you are asking for help on a DIY hvac video some loser posted you are in over your head.
Replying 3 years later to a question, a calling poster a loser. I'm a year late but damn, read the time stamps lol
please help I have a york central ac unit the fan outside works ......but I'm not getting air in the house...........does that mean the blower motor is out........ohh yeah there's ice build up on condenser outside ....not sure if that matters.......hope is a easy fix
It could just be your blower motor capacitor. 1:02 it's worth checking. See my latest video on how to test a capacitor.
I turned it off last night ...now it works. what could happen
It could be several problems. It should have a flashing LED code when it shut off. But it will stop flashing once the system resets. Next time it turns off check the LED and count the flashes.
Awesome video!
why? The heater in my home fans smell of cigar house winged neighbors? help!
I have no idea how I came upon this comment, but it is EXCELLENT.
do you have a email I can send you a picture of were ice is building up on hoses
David Lee, your cheap, dumb butt needs to call in a hvac tech. Sounds like your unit is low on refrigerant. Hope this helps.
It’s out of balance because you pressure washed it
