Ok this video just saved me hundreds of dollars and time. I thought I needed a new inducer motor/fan assembly but it turned out to be vibrations caused by a few different things that this video helped me identify. My furnace now has a pleasant quiet hum instead of an obnoxious rumble/rattle. Read on for the fixes. The plastic cooling fan on the end of the inducer motor was loose. Refer to 5:07 in the video to see this fan. You have to snug up that push nut because it becomes loose after years. Just push with a tool or your two thumbs. Also look for things that are fastened to the side of the furnace like electrical conduit. I put some foam rubber between this conduit and the furnace so it wouldn't vibrate against it. There was also a metal strap that was screwed to my duct work that was supporting the metal gas line. Major no no. I isolated this metal strap and tied it to a wood floor joist above. The duct work and furnace can act like a speaker amplifying any mechanical vibration. So the inducer motor and fan still makes a little noise but it's a very gentle hum that is no longer obnoxious. Thanks to the author of this video. I could have spent $230 on a new inducer motor/fan and still had the same noise. I can't even hear my furnace anymore when my TV is on. Awesome.
Glad to help!
Love this site. Appreciate all the videos. I work in the trade. I'm a Chief Engineer for a highrise building. The videos you put out are helpful and clear to the point.
Thanks a lot Carl!
Great video!!! My Carrier inducer impeller starting "gurgling" this fall on startup. It has a plastic condensate box screwed on the housing. Had dead bugs in it. Cleaned it out and no more gurgling.
Thanks for the info. What I wished we had were actual examples of the noises of each case.
Knott thanks for letting me know!
Well done! The need to know for all who live in homes using such furnaces.
I always enjoy watching these videos. Thank you. Those motors can be a pain sometimes to get off and replace. Good scenarios of this part. Thank you enjoy your SUPER BOWL WKND. HVAC ON!!
For sure, thanks Ray Ray!
Thanks for this video! I was having water build up in my inducer motor and after having a long stretch of mild weather, I found that mold had plugged the condensation drain tube. So I poured a bleach jug cap full of bleach into the drain tube and that cleared it. I also found that the drain tubes were kind of collapsed which restricted flow.
Nothing but the best out of this channel !!!
Thank you Craig
Thanks a lot Thomas!
AC Service Tech LLC I recently attempted and succeeded in replacing the two bearings out of ICP’s 1172823 using a shop press !
Bearing is stamped 608 but it’s actually a smaller ID size
Oh cool, nice job!
Replaced mine today, contractor wanted $750.00 to replace, I purchased my own, $200.00 , I installed 20 min. It's a good day.
I just had quote of $669 to replace inducer motor on 20 year old 80% furnace, which I'm now questioning because repairman did not check one thing on it at all. He turned the heat on, furnace was making a loud noise, he turned furnace off and said noise was coming from inducer motor, and it needed to be replaced. With 11 years experience repairing furnaces, can he tell simply from the noise it's making?
I found 3 mice jammed in an 80% Goodman ID motor once. They had to have traveled all the way through the heat exchanger from the burners.
Good stuff Craig!
Wow nice! Yeah I have had those problems mainly on 80% eff furnaces near the ground level, thanks Tomon8tor!
Or they came threw the vent
Video would have been better iif there were actual corresponding noises as examples.
Great video! Concise and straightforward. Thank you.
Glad you enjoyed it!
love all your videos please keep them coming !!!
Thanks PBS #007!
Mine turned out to be #5. Thanks - great video, with clear descriptions.
Glad to help Mert!
thank you, partner, for sharing! I love all your videos!!!!

My favorite HVAC educator !
Thanks a lot Tony!
Appreciated your cristal clear explanations.
Thanks a lot Juan!
Thanks for the great video! I am not sure if my issue is any of these through... my noice begins at start up but it has a grinding noise. Kind alike gears slipping. Any idea?
A couple years back. Four Seasons, charged 950$ to install a new inducer motor. I could've bought a NEW furnace! Now the motor is lacking power and not getting to optimum temperatures. I think debri from a 100 year old crumbling, never capped chimney debri, is one of the culprits. I keep hearing drafts. And when removing the exhaust I saw a good amount of chimney dust. I found new inducers as low as 100 to 125$ (still can't believe I got robbed for 950$) I'm gonna replace myself. I know I'm just buying time until I replace or repair my chimney, and cap to reduce drafts. Then I'll buy a new furnace. That's the 2nd issue. It's over 30 years old, and now it has AC hooked up to it. Thank you for this video. We are getting ripped off by repair "Professionals".
how can you talk about someones price they charge for a skill when you don’t possess said skil
@@elijahsalas6170 life experience.
@@dannyramirez8428 yes this life experience is why we charge what we charge we go to school for 5 years have to pay for tools gas office staff truck maintenance ,repairs and make a profit
You are very welcome
Good video...Just serviced a noise problem and it was the inducer motor blower wheel rubbing....It was erratic, but mostly on start up...I shimmed one bolt, on a three bolt mounting, used a paper clip, snipped the excess off.....It did the trick....Sometimes you just have to improvise....lol....Thanks for this video.
Absolutely, thanks Vern!
Always great info!
Thanks Familia Sanchez!
Hi there, great video. Have you ever seen a situation where for the first week or two in the fall the inducer motor makes a loud noise then stops and doesn’t do it again until the following fall? I had a technician out who suggested replacing it but it’s really expensive. A couple days later - just like the year before - it stopped making the noise. My theory (not any kind of tech in any way) is that when everything was physically cold something was rubbing, or causing a vibration, once everything got up to temperature and the furnace was on more it was happy. Thoughts? Thx!
Thank you ! Very helpful information)))
Thanks Tapch MC!
I have a scraping sound that is only sometimes on startup and when it’s shutting down, slower speeds. Sounds like it’s metal on metal. I just had a nicor tech said he fixed. It’s still happening. Any chance it’s the American standard doors being right on top of the inducer. What can I put to wedge the doors up a little higher that is not flammable because the doors do get hot.
When endured motor goes bad do you need to change the whole furnace? My furnace is over 40 yrs old
I have a noise I can only describe as sounding like a medium pitched beeping, almost like a resonating pulsing sound. Thoughts
Mine seems like #5 at 5:07 but I'm not 100% sure of the root cause. It has a low pitched vibrating noise that's pretty loud until the main furnace fan starts. It's been like this since I bought the house 3 1/2 years ago. You can push and pull on the end of the motor shaft with about 1 mm of play. Not sure that causes any vibrations. Also the plastic motor fan is held on by a special push nut that was not tight. The push nut was not snugged up to the fan. I pushed on this and now the fan is not as loose. I'll keep monitoring it. The other thing I want to do is try shimming the motor mount. It's possible that the fan/motor is sagging due to gravity after years of operation. The furnace itself is perfectly level. I'd like to rule out simple things before spending hundreds on a new inducer assembly. Edit: Ok results are in for snugging up inducer motor plastic fan: much quieter. I also tried moving the motor/fan in different directions a tiny bit while it was running, simulating a shim and it didn't get quieter. You can grab the mount near the grommet pretty safely. I'll keep an eye on it and post back.
Hi, what is the make/model of the first inducer you showed in your video? I have the same one and it stopped spinning today. I might need to order a new one.
when to use a secondary inducer motor on 80% furnace going through the outside wall & why you need one??
Nice video ty
Thank you for your support!
Some carrier inducers just run with a bit of water in them. They even had a service bulletin for new boards to ignore temporary pressure switch closing
Thanks Detis! Do you have that bulletin number?
@@acservicetechchannel no I don't have that, heard about it by taking to some carrier techs in town. Just recognized the symptoms on a call last week.
I’m wondering if it’s possible to order the bearings and replace them instead of buying a $200 unit?
Our 9 years old Carrier Infinity 96 furnace, Model # 58 MVB120-F-12120, has an inducer motor unit just like the one you show at the 7 minute mark of your video. I replaced the 2 bearings (608-2RS 5/16") for the motor. It ran quiet after the repair. 6 days later the exact same growly noise came back. The noise would go away if you push the motor in a certain way but come back readily! Any help you can give? What's the replacement part on Amazon? Much thanks!
My Fasco inducer motor wheel is coming off and I can't get the set screw to keep the wheel on. It's making so much noise. I want to replace the inducer fan but I can't find a proper replacement anywhere! My fan has a high pressure and low pressure inlet valve. The replacement only has one of them. I can't find one that has both! That means I'd have one of the two pressure hoses not connected :( - helppppp
My gas Lennox hanging heater inducer is very loud. It rattles and rumbles, but when I push on the back of the motor, the noise almost completely stops. all the visible nuts on the outside are tight. If the bearings were bad, would the noise disappear when pushing on the back of the motor?
Thanks.
If the bearings are shot, is replacing them instead of the entire motor a feasible option?
Thanks for the video. My inducer fan was all gummed up with debris. I pulled it off, cleaned everything thing out and my furnace is whisper quiet again.
Glad it helped
Thank for this great video. It looks we have a wheel rubbing problem as defined on #5 on our Payne high efficiency furnace, pg9mxa. I thought it was the wheel warped but when I compare it with a new one, them seem identical, no warping, cracks, etc. The wheel housing looks OK. The noise is gone when I push the motor shaft/wheel back. Is there a way to keep it pushed back?
Not really, there must be play in some part of the setup that is allowing that to happen which you could mount something to but in most cases, the entire assembly needs to get replaced, thanks!
I feel like my furnace sounds like an idling car, and it’s even woke me up on our top floor, furnace in basement, is it likely inducer? Goes for couple mins then stops and air continues for a couple mins
The sealed bearings in my Fasco A204 made noises for a very short period last season & stopped. Then this season it started again about a month before spring. Continued to make VERY loud noises upon start up. Still functioned for about a month then the bearings totally prevent it from cycling up. I can see the inducer wanting to spin but just barely moving. Pretty sure my bearings are bad. Humid basement is the cause.
I know this comment was made long ago, but did you end up replacing your inducer motor?!
What about capacitor issues
Pigion in the inducer wheel? Have had that happen.
Poor thing fell down a 70' chimney then climbed down 12' of 4" line then it's head got caught in the fan of the induction fan making it stop...
We have a brand new 95% two-stage furnace. When the inducer is running in the low speed you can hear a bit of a "crackling" sound that is very faint coming from the inducer area I believe. You can hear it if standing in front of the furnace, or if your ear is near the exhaust output on the exterior of the home. Any thoughts? When running in high speed you don't hear it anymore. It is also not constant or consistent and seems to only be noticeable (for me at least, very sensitive to sounds) when the furnace initially turns on.
sounds like water
@@sku32956 It was! The service tech came out and found a FLY clogging one of the small rubber drain lines for the inducer motor. The fly was wedged up against the strainer that is in the line. It was quite hilarious actually, to see its little fly butt sticking out once the hose was detached.
They did say that it is normal to hear some on startup, which we still do, but it is considerably less and eventually disappears entirely. The fan blades are plastic so I believe that perhaps the sound is amplified more in comparison to other types of motors with metal fan blades.
Im so glad im learning these things too late
Why does my furnace sound like drums when it blows out hot air and only when it blows out hot air
My inducer motor sometimes sounds like it doesn’t want to start. It’ll try three times and I have to reset the furnace. Should I just replace the motor? Also noisy sometimes during the first 15 seconds. Thanks!!
@ Tamar Habeeb Any update on the cause of this, or the fix??
Its clogged, clean it and clean the condensate pump
Is it possible that the circuit board relay is stuck and not shutting off the power to the inducer motor
Yes if you don't measure 24v between w to c with the multimeter on the control board but the inducer is running then the relay could be stuck in the closed position, thanks!
AC Service Tech LLC Could we just unplug it since we don’t use the heater? Would it affect the AC
The furnace is usually part of the ac system unless the ac is another unit, thanks
AC Service Tech LLC There is another unit on the side of the house. Should we be ok?
If the unit outside is just your outdoor condensing unit then the ac uses the furnace blower and control boar to control the air conditioning, thanks
My furnace hums about four times when it first starts up. Is that normal?
Not usually, thanks
I bet there were feathers in there whether we looked or not.
Sorry.. but a "loud noise" is rather vague.. Mine sounds like a table saw.. intermittently. I'm just guessing motor bearings.
Wow, water sloshing inside the inducer motor because the furnace is not pitched correctly ???
Talk about a LOUSY design !!!
If they put that design feature in their advertisement, nobody would buy that furnace.
Am I glad you don't teach brain surgery or dentistry.
So...
My unit was making a noise, was told by hvac guy that it was bearings and they had to order part.
Now my unit quit working. Turned thermostat off and on, it worked for a minute and shut off.
Turned off and on again now it's working and not making any noise.
Should i be concerned?
