This video will show how I removed and replaced a Carrier furnace blower motor. The model number on the furnace was FH4CNF003. The motor is model number 5KCP39PGS084S.
Videos like this really help American Dads like me! You know....the screw it, I'm not paying, do it type 😆. I am a gas station maintenance technician with some residential hvac experience, but I've never changed a blower motor. Thanks a lot for taking time for all of us out here trying to save money and fix it right on our own!
Thanks so much for taking the time to leave a comment, Robert. Makes my day to know the video helped a hard-working American dad like you. Good job on getting it done yourself!
Thank you for this video! I’m handy but not a handyman or construction type worker so I did call the HVAC tech in to diagnose the problem. He said it was the furnace blower motor. The part alone was supposedly $1464 the install was over $500. I bought the appropriate exact new gen replacement for $300. With your help it took me about 45 minutes to install. Everything went perfect and like the breath of the heavens cold air once again flows from the vents! Perfect instructions! Saving this for the next time!
Thanks ! As others have said, it is really nice that you made this video. I had discovered my blower had some slides, but didn't know what I might be in for after I got it out. Great to see how the mounting is done and how the fan blade cage is attached to the motor shaft. Thanks for taking the time to film this and put it up on UA-cam for others to learn from !

I live out in the boonies and just to get someone out to my house is a hassle due to where I live. I've become pretty handy on learning how to fix things. This video is awesome if the need ever arises that I would have to replace my blower motor. I hope I never do, but this video provided awesome instructions and I would not have a problem tackling the job myself! Thank you for posting it!!
I am really glad it helped you out. Thanks so much for taking the time to leave a comment. I appreciate the feedback. Congratulations on having the confidence to do it yourself and for saving some money, you should reward yourself this weekend!
Man thank you so much for posting the whole process. There were little things I was unsure of like the wiring to the capacitor if it mattered which wire went were and other details, this helped me out a lot. $200 part, probably saved me at least $500 in labor (just a guess). Take care.
Thank you video. Nice work on that furnace. (It helped & encouraged me to press on towards replacement of our furnace's failed motor [it's on order]). I'm not ready to spend big $ for a new furnace. Perhaps in a year or so. Thank you much.
Thank you for the video! Mine was squealing like a mofo. Did your step by step, cleaned the motor then put it all back together. It’s quiet again. God bless!
Good, but you should add a segment where the freaking fan is stuck on the shaft and you have to use a puller to get it off. That is my experience in the past when I replaced one.
This video is a godsend! I was able to test AC with a new capacitor but that didn't work. I was able to remove the blower and ordered a new motor. I will post details once I receive the motor and install it. Again thank you for this very informative video.
02:28 you didnt short out the capacator first before pulling the wires.. playin with fire! ALWAYS ALWAYS ALWAYS short out the capacator before you touch it, use a screwdriver and cross the terminals to drain it
I had to pull the blower motor from our Goodman furnace ... the blower fan was vibrating the whole furnace and making a noise in the house . I suspected the motor bearings but found the blower blade assembly was failing mechanically. Getting the fan assembly out in the hot attic was not fun . Replaced the blower fan and everything was good again. The AC place said blower fan mechanical failures were not uncommon.
Hey, sorry for the long delay. I must’ve missed your question and comment. I think your idea about testing the relay. It’s a good one. Definitely should do that first!
I need the blower motor for both AC and Heat, correct? Mine makes the same noise but never turns on, think I should attempt to buy a new one and change it myself? My furnace is in the attic, thank you
Yes, the blower motor blows the air through the vents, regardless of what hears or cools it. If you have already checked the capacitor (lots of places you can Google to learn how to do that) and know that the capacitor is good, then try replacing the motor. If it’s in the attic, that’s OK, as long as you have room to work.
Thank you for the video! Question for you: we have a boiler for heating our house and what appears to be the old furnace and ducts- we have a fan that runs with an air filter as part of the old furnace system and the last several months it’s been kicking on and off at odd intervals and not running the correct amount of time. Any idea what might need to be fixed?
@swey289 sounds like it’s short cycling (when a furnace fan turns off and on frequently). You might be able to fix some of these, but a professional might need to be called for others. it’s going to be one of a few different problems. It could be a faulty fan limit switch. That switch turns the blower on and off based on the information it gets from a temperature probe. A bad switch can keep the blower from turning off after the burners has stopped and the air exchanger is cool enough you could test the limit switch with a multimeter. It could be a dirty air filter. Air filter that’s very dirty can cause the furnace to turn on and off more often. You could have leaky or poorly designed ductwork, a furnace that’s too big, abnormally, high or low heat exchange temperatures, corroded, or dirty flame sensor, obstructed airflow from closed, vents or returned, ducks, or the blower motor could be malfunctioning The furnace should only be going through about 2 to 4 heat cycles each hour. And each cycle should last 5 to 15 minutes depending on your thermostat setting and how cold it is outside.
That yellow wire? No, it was the motor. I later tried tested the blower motor I removed to see if it would spin when connected to power. I wanted make a high volume fan to blow on me and to help to keep mosquitos off me when chilling at camp. The fan wouldn’t turn hardly at all. Actually, in my limited experience, there is either enough current or not any current. A loose wire doesn’t produce less voltage …it produces no voltage.
On my unit, that shorter ground wire is connected at the closest bolt that holds one of the suspension arms to the cage. I don't believe there was any need to change it to the older longer one. Just change where it connected to the system. A ground is a ground.
Yes, I agree with you, a ground wire may be connected to any solid ground that does not interfere with the unit’s mechanical or electrical operation. Rather than extending the existing ground wire by splicing in new wire, I’d probably just relocate that wire to a new or existing ground like you did. Thanks for the comment!
Thanks for taking time to post this. I need to swap the fan motor on a 50 year old Carrier furnace, you have any idea where I might be able to find a motor for a blower that old? Like maybe a parts place that specializes in old stuff like that?
Well, you could get the current make and model off the old motor and google it along with words like “equivalent” or “replacement”. However, there are also companies that specialize in rebuilding motors, so try that too. Lastly, google “HVAC Supply” in your city and take the old motor to them. They have resources to look up and cross reference the motor. Thanks for the comments and the question. Let us know how it turns out.
@@maintenanceman1503 Thanks for the quick reply. I'll pull that sucker tomorrow and see what I kind find. Good call on the motor rebuild too, I hadn't thought of that.
@@maintenanceman1503 Quick update, found a new motor through Grainger (super helpful), and got her done today. 55 years old and she's working still! Thanks again for posting this video and taking time to offer guidance. Guys like you are appreciated by guys like me.
Great video! You are a straight shooter! Question, when I spin the wheel it warbles, do you think i can get away with just chaning out the wheel? The reason i am in here is that its 1) squeaking a bit and 2) out of balance. Wondering if its a bearing, motor or just the wheel. Appreciate the advice if you can spare any!
@@maintenanceman1503 Where would that bearing be if I need to replace it? In the wheel or motor? It looks like the wheel, right? I pulled the assembly, took it apart, and cleaned it. There was long hair wrapped around the shaft and dog hair in the wheel. 🤢 It seems that whoever owned the house before me had dogs and rarely changed the filter. Anyway, it took 3-4 hrs and now there is no rattle or squeak even if it is wobbling a little still! Might not need to replace this year! Thanks for giving me the confidence and know-how to tackle this myself! Saved $1500!
I just need my blower and maybe capacitor changed every time someone comes out they say need new unit never had an issue with regular updates on it might just do it my self
I’d recommend you use an existing ground point. For example, the existing ground wire that is a jumper between the motor housing and the frame (since they could become separated). Put a ring terminal on it and attach it under the screw with the green/yellow wire.
Thank you for posting great content. I need some advice if you don't mind... I replaced a blower motor and cap on a wood furnace for a elderly couple from church as a favor. When I realized the motor was rotating the wrong direction, I swapped wires after disconnecting power. The motor popped and sparked when I reconnected power. Should I have turned the thermostat down before reconnection power out did I do something else wrong or what? The motor was running smooth in the one direction and all I did was swap the wires (the ones for bidirectional motor) and no worky. Will I have any issues returning the motor for a new one? Thank you for your time! Chris
🤔 Hmmm …. Dang Chris…Gonna have to think on that a little. I assume the motor was an exact replacement (correct part number for that furnace) and all that, right? As far as returning that motor, I guess it depends. Does it still operate in the “wrong” direction?
@@maintenanceman1503 Hey I appreciate your attention on my dilemma. So the old motor was quite old and the nameplate info was worn off. I brought it to the parts supply and he wasn't very helpful so I brought it to Savannah Electric and Supply Inc and the tech that was in there was able to identify it as a 1/2 hp motor and I went back to the first place to request the appropriate motor. The 1/2 hp was the last remaining info so there was just the one option of motor to purchase. I can take a picture of the old motor today but the new one might not be able to get to right away.
Ok, I have your email. Looks like you attached the link to the website that listed the motor. I searched through it, but could not find the wiring diagram. Did one come with the motor?
Is it possible for my blower motor to not have a compositor? I’ve looked everywhere on this motor and I don’t see one. AC unit outside works properly but this blower motor fan is not spinning just humming
@@maintenanceman1503 I appreciate you responding. Sorry about my misspelling lol. Yes Sir. I have a Carrier Unit in my attic I believe I have a ECM unit and not a PSC unit. I think that why I could not find a capacitor on the unit. So the issue might be my Modular on the blower. I’m going to look into it further. I appreciate you Sir truly
@@troywaterman7123 I have the same issue. A motor with an ECM. Trying to figure out if its the control board or the motor/ECM. Not sure what the signals are on the wires going to the motor/ECM though, so trying to find out so I can diagnose between the control and the motor (has a 5-pin standard-ish connector, and another connector with about 16 black wires on it.) Hmm.... I think I've ruled out the thermostat as the Fan-ON signal seems to be present. Good video by Maintenance Man !
@@MegawattKS Turns out it was my Motor. So I just Ordered an Evergreen X13 1/3 from Amazon. Exact fit. Works like a Charm now. My local HVAC wanted to bill me $1325 for a $230 motor. Did it myself from the video. Thanks guys
I have the same unit, I connected the common wire just like you did but not getting any power, and I connected to the black terminal and started running, so is it OK too leave it on the third terminal with the black wire?
That is really weird. Does the motor turn in the correct direction? (does it blow air like it should) with the black wire hooked up or is it operating in the opposite direction?
No. You’ll need to pull the motor and look at the data plate. You can take the motor into a HVAC supply store (Google for one in your area) and they can help you find one that matches.
I found it common at that facility because it is a mountain summer camp with dirt roads, foot paths, and lots of dusty kids. After I took over as maintenance director, I started scheduled maintenance for cleaning and filter changes.
Hi Gregorio, I’m doing good and hope you are well. That’s a great question! I found my motor on Amazon. 5KCP39PGS084S - Genteq Replacement Furnace Blower Motor 3/4 HP 230 Volt 3 SPD 1075 RPM www.amazon.com/dp/B00IMN04Z8/ref=cm_sw_r_cp_apip_ljj6QpXHhmDAB
Hi, thanks for your question. No, I don’t think so. But I would recommend that you replace the capacitor first or at least check it with a multimeter to make sure it’s working. There are lots of UA-cam videos showing you how to check your capacitor with a multimeter. If the capacitor is good, then yes, it’s most likely your inducer motor. I would just replace the motor, not the whole system.
@@maintenanceman1503 thanks a bunch for the fast response. Yes, I’ll prefer change the enducer motor & fix any other minor issues. Thank you so much, the guy tried to scared me, because I just moved less than 10days ago.
I am so jealous because you do not have my furnace Carrier 376CAV060096 from hell (which is installed around 1988.) The reasons are: 1) Your carrier does not have a "stupid" tube or vent pipe installed horizontally blocking me accessing to the furnace fan motor housing. 2) After removing that stupid tube or vent pipe, yours do have another silly circuit board which is hanging on top and have lot of wires such as thermostat wiring, temperature sensor wiring ... connected to it which is blocking me again. 3) After the circuit board, I have a fan motor housing which is about 17 inch x 17 inch but I only have room of about 15 inches on the entrance front and then back against a wall on the attic. basically, he housing cannot be completely come out. I still doing research and homework on how to replace the fan motor if it stops running and my best bet I think is to loosen lock screw on top where it stands and then loosen the motor mounting and the slide out the motor as your original plan and then slide the motor back up. I have to perform all these in the attic with housing half out. By the way, my carrier is installed horizontal due to not enough head room. I think the most important is to take picture on all the wires so that it will go back to the original position but it is going to be pain due to limited space. Thank you so much for your video 👍 it really helps me a lot. 😁
Most HVAC technicians charge somewhere between $60 and $80 an hour. There may be a service trip fee (an additional charge for driving to your place if you are in a remote area) depending on your location.
It means the bearings in the motor are worn out or the motor shaft is bent. You’ll need to replace the motor. Take the old one with you to your local HVAC parts company or google the make and model of the motor and find a replacement online.
Kevin, the best way to identify the part numbers to order a specific component is to do google a search for the make and model of your furnace followed by “parts diagram”. For example when I google searched for “carrier model FH4CNF003 parts diagram” I found the following link: www.searspartsdirect.com/model/2q5t8r8e7v-003079/carrier-fa4cnf030000aaaa-air-handler-parts
@@maintenanceman1503 thanks for replying... so I bought this house a few months ago, now the ac went out. I did a troubleshooter and found that the blower motor isn't working. After some research and seeing your video I realise that my furnace is missing a capacitor, I can see the spot where it belongs. now here is the confusion, doesn't it need a capacitor to work?
Hey Kevin! Congrats on the new house. Yes, I think the capacitor is needed for the furnace blower motor to work. Every blower motor needs an extra “jolt” of power to lose its inertia and get it turning when it first starts up. The fan or blower motor may not be able to start and blow air without the capacitor there to provide that “jump start”. You mentioned that you can see the spot where the capacitor belongs. So are there wires just hanging there not attached to anything?
@@maintenanceman1503 no I haven't noticed any wiring hanging I look at the motor and all the wires seem to be attached, could it be that the capacitor is on the outside unit? (just guessing)
According to the article I just read (link below), capacitors are used in many but not all electric motors including air conditioners, heat pumps, furnace or air conditioner blower fan motors, refrigeration equipment compressors, and well pumps. inspectapedia.com/electric/Motor_Capacitor_Location.php
No offense but why don’t you have a meter to test the capacitor and amp draw of the motor. All I see is just guessing and changing a bunch of parts that have not possibly failed. HVAC tech here by trade. Invest in a meter it it’s the number one tool in troubleshooting or your going in blind. And it will save you a ton of time
Oh, I’ve got a meter, just no formal HVAC training in how to use one! Electrical issues are my weak side (if I can’t see it, it’s harder for me to understand it). You make a great point and I appreciate the comment. If you decide to make a video on how to troubleshoot an issue like this with a multimeter, let me know. I’d really appreciate the wisdom!
@@maintenanceman1503 Get a Fluke 902FC it’s super easy to use like super duper and I use that to trouble shoot residential and commercial hvac and refrigeration I can explain it to you in 10 mins and you will be a master and your job will be ready 1000 times easier and fun I use mine for around the house as well as car and boat but before I learned I couldn’t even wire a stereo lol
I knew someone was gonna comment this lol. My boss stays on my bumper about making sure to use my meter to fully diagnose the problem so I solve the issue once and for all. The training on the multimeter definitely comes in handy daily, but I gotta salute you for being able to get the job done in spite of not knowing how to use the meter. Problem solved and a job well done sir! How long have you been working in the HVAC trade? Ive been in commercial on a college campus for 2 years now and I worked on an HVAC detail for a year while I was in federal prison.

Well it depends on what controls that fan. Does your wall thermostat turn it on when you set it to “fan on”?

The wheel has bearings and the shaft of the motor also has bearings. If the wheel warbles when you spin it, it’s almost positively the wheel.

Can you ground it on the housing blower motor

The 1/2 hp was the last remaining info so there was just the one option of motor to purchase. I can take a picture of the old motor today but the new one might not be able to get to right away.
Ok, I have your email. Looks like you attached the link to the website that listed the motor. I searched through it, but could not find the wiring diagram. Did one come with the motor?
@@maintenanceman1503 No sir. No writing diagram
Is it possible for my blower motor to not have a compositor? I’ve looked everywhere on this motor and I don’t see one. AC unit outside works properly but this blower motor fan is not spinning just humming
Troy, did you mean to say you can’t find your motors CAPACITOR? If so, try this web article:

@@maintenanceman1503 I appreciate you responding. Sorry about my misspelling lol. Yes Sir. I have a Carrier Unit in my attic I believe I have a ECM unit and not a PSC unit. I think that why I could not find a capacitor on the unit. So the issue might be my Modular on the blower. I’m going to look into it further. I appreciate you Sir truly
@@troywaterman7123 I have the same issue. A motor with an ECM. Trying to figure out if its the control board or the motor/ECM. Not sure what the signals are on the wires going to the motor/ECM though, so trying to find out so I can diagnose between the control and the motor (has a 5-pin standard-ish connector, and another connector with about 16 black wires on it.) Hmm.... I think I've ruled out the thermostat as the Fan-ON signal seems to be present. Good video by Maintenance Man !
@@MegawattKS Turns out it was my Motor. So I just Ordered an Evergreen X13 1/3 from Amazon. Exact fit. Works like a Charm now. My local HVAC wanted to bill me $1325 for a $230 motor. Did it myself from the video. Thanks guys
That’s so good to hear! I’m glad you saved the money by doing it yourself!
Where did you get motor?
We found it online.
I have the same unit, I connected the common wire just like you did but not getting any power, and I connected to the black terminal and started running, so is it OK too leave it on the third terminal with the black wire?
There should be a little fuse, the blade type, like you would find in an automobile, make sure that the fuse hasn’t blown
@@maintenanceman1503 fuse is good, just no power thru the common side but there is power thru the black side
Did the furnace ever work when it was wired with the common side as the power source?
@@maintenanceman1503 yes
That is really weird. Does the motor turn in the correct direction? (does it blow air like it should) with the black wire hooked up or is it operating in the opposite direction?
Are all the blower motors the same?
No. You’ll need to pull the motor and look at the data plate. You can take the motor into a HVAC supply store (Google for one in your area) and they can help you find one that matches.
Dirt inside that unit seems to be excessive. Especially inside that motor.
I found it common at that facility because it is a mountain summer camp with dirt roads, foot paths, and lots of dusty kids. After I took over as maintenance director, I started scheduled maintenance for cleaning and filter changes.
Hello sir how are you? My furnace have the same problem 😒 where I can find the motor? Please let me know .
Thank you Have a great day.
Hi Gregorio, I’m doing good and hope you are well. That’s a great question! I found my motor on Amazon.

Lord it’s sexy watching a man do this lol 😂
Enducer motor not working but my furnace is over 40 yrs old, do I need to change my whole furnace system?
Hi, thanks for your question.
No, I don’t think so. But I would recommend that you replace the capacitor first or at least check it with a multimeter to make sure it’s working. There are lots of UA-cam videos showing you how to check your capacitor with a multimeter. If the capacitor is good, then yes, it’s most likely your inducer motor.
I would just replace the motor, not the whole system.
@@maintenanceman1503 thanks a bunch for the fast response. Yes, I’ll prefer change the enducer motor & fix any other minor issues. Thank you so much, the guy tried to scared me, because I just moved less than 10days ago.
I am so jealous because you do not have my furnace Carrier 376CAV060096 from hell (which is installed around 1988.)
The reasons are:
1) Your carrier does not have a "stupid" tube or vent pipe installed horizontally blocking me accessing to the furnace fan motor housing.
2) After removing that stupid tube or vent pipe, yours do have another silly circuit board which is hanging on top and have lot of wires such as thermostat wiring, temperature sensor wiring ... connected to it which is blocking me again.
3) After the circuit board, I have a fan motor housing which is about 17 inch x 17 inch but I only have room of about 15 inches on the entrance front and then back against a wall on the attic. basically, he housing cannot be completely come out.
I still doing research and homework on how to replace the fan motor if it stops running and my best bet I think is to loosen lock screw on top where it stands and then loosen the motor mounting and the slide out the motor as your original plan and then slide the motor back up. I have to perform all these in the attic with housing half out. By the way, my carrier is installed horizontal due to not enough head room. I think the most important is to take picture on all the wires so that it will go back to the original position but it is going to be pain due to limited space.
Thank you so much for your video 👍 it really helps me a lot. 😁
Wow, I would lose my mind with one built like yours. Good luck with that. Sounds like tough job!
Hope you move to Belize
Me too Tashtan!
See you in Belize. 😄
Man, that would be awesome! Someday……
How much would a hvac person charged for this, seem like i might be getting screwed
Most HVAC technicians charge somewhere between $60 and $80 an hour. There may be a service trip fee (an additional charge for driving to your place if you are in a remote area) depending on your location.
My guy quoted 1200-1500 with parts. I'll be doing it myself. 😅
Good for you! Let us know how it went.
What if when you check the motor the motor is seized up and hard to move? What would that mean?
It means the bearings in the motor are worn out or the motor shaft is bent. You’ll need to replace the motor. Take the old one with you to your local HVAC parts company or google the make and model of the motor and find a replacement online.
You’re a life saver. Thank you.
Glad to help!
Seems like you are flying by the seat of your pants.
how do I identify the Part number in order to order?
Kevin, the best way to identify the part numbers to order a specific component is to do google a search for the make and model of your furnace followed by “parts diagram”. For example when I google searched for “carrier model FH4CNF003 parts diagram” I found the following link: www.searspartsdirect.com/model/2q5t8r8e7v-003079/carrier-fa4cnf030000aaaa-air-handler-parts
@@maintenanceman1503 thanks for replying... so I bought this house a few months ago, now the ac went out. I did a troubleshooter and found that the blower motor isn't working. After some research and seeing your video I realise that my furnace is missing a capacitor, I can see the spot where it belongs. now here is the confusion, doesn't it need a capacitor to work?
Hey Kevin! Congrats on the new house. Yes, I think the capacitor is needed for the furnace blower motor to work. Every blower motor needs an extra “jolt” of power to lose its inertia and get it turning when it first starts up. The fan or blower motor may not be able to start and blow air without the capacitor there to provide that “jump start”. You mentioned that you can see the spot where the capacitor belongs. So are there wires just hanging there not attached to anything?
@@maintenanceman1503 no I haven't noticed any wiring hanging I look at the motor and all the wires seem to be attached, could it be that the capacitor is on the outside unit? (just guessing)
According to the article I just read (link below), capacitors are used in many but not all electric motors including air conditioners, heat pumps, furnace or air conditioner blower fan motors, refrigeration equipment compressors, and well pumps.

Always put the connector in the crimper first then put the wire in it, fyi
Makes sense. Thanks Joe.
How much did the blower motor cost
I don’t remember exactly, but I think it was right around $60.
About $60
You never discharged the capacitor before playing with it
I did off camera? 🤔
Omg I did it the hard way 🤦🏻♂️😂
Next time you do it the easy way! Did you get it fixed?
your video made it so easy to replace furnace blower motor. For quality Utica-Dunkirk furnace blower motor spare parts, visit our site.
Thanks, a lot of people are wondering where to get that specific motor. Maybe you could provide a link directly to the motor itself?
No offense but why don’t you have a meter to test the capacitor and amp draw of the motor. All I see is just guessing and changing a bunch of parts that have not possibly failed. HVAC tech here by trade. Invest in a meter it it’s the number one tool in troubleshooting or your going in blind. And it will save you a ton of time
Oh, I’ve got a meter, just no formal HVAC training in how to use one! Electrical issues are my weak side (if I can’t see it, it’s harder for me to understand it). You make a great point and I appreciate the comment. If you decide to make a video on how to troubleshoot an issue like this with a multimeter, let me know. I’d really appreciate the wisdom!
@@maintenanceman1503 Get a Fluke 902FC it’s super easy to use like super duper and I use that to trouble shoot residential and commercial hvac and refrigeration I can explain it to you in 10 mins and you will be a master and your job will be ready 1000 times easier and fun I use mine for around the house as well as car and boat but before I learned I couldn’t even wire a stereo lol
I knew someone was gonna comment this lol. My boss stays on my bumper about making sure to use my meter to fully diagnose the problem so I solve the issue once and for all. The training on the multimeter definitely comes in handy daily, but I gotta salute you for being able to get the job done in spite of not knowing how to use the meter. Problem solved and a job well done sir! How long have you been working in the HVAC trade? Ive been in commercial on a college campus for 2 years now and I worked on an HVAC detail for a year while I was in federal prison.
