Thanks for the great tutorial; took me 45 minutes and saved me hundreds! I had no idea how much noise this little motor was adding to the furnace sound - it's now whisper-quiet. Tip #1: Get your specific model number before looking for parts. There are numerous versions of the Weathermaker that require different parts. Remove the front door and look inside the unit. The model # is printed on a decal (include the numbers after the "- - -"). Take a picture of it to reference later. Tip #2: Buy the $5 replacement fiberglass gasket rather than deal with messy silicone. When you remove the motor assembly, the original fiberglass gasket will fall apart. To ensure a good seal, remove as much of it as you can before attaching the new one. NOTE the new gasket is fragile so handle gently. Also, install it DIRECTLY onto the furnace, not to the motor assembly you detached. Tip #3: If you don't have a magnetic-tipped nut driver, you can use a bit of tape to hold the screw to the driver. Once the screw bites, remove the tape and finish setting the screw. My Weathermaker model # 58CVA090-10116 required the following parts, purchased from factory-authorized repairclinic dot com: Draft Inducer Motor -- Genuine OEM Part #: HC21ZE126(A) -- Repairclinic Item #: 2378490 Draft Inducer Blower Wheel -- Genuine OEM Part #: LA11XA048 -- Repairclinic Item #: 2347724 Fan Blade -- Genuine OEM Part #: LA660003 -- Repairclinic Item #: 2347727 Gasket -- Genuine OEM Part #: 327263-401 -- Repairclinic Item #: 2357539 Total Cost -- $140 including shipping

Thanks for the positive feedback and quality input. I pinned your post so others will easily benefit from your great suggestions!

Thanks for the video. It provided some good information that helped me. I just replaced mine tonight. I decided to just get the whole assembly for mine off Amazon for about $300 so I didn't have to worry about swapping parts or breaking the plastic fan when trying to get it off. I just unscrewed the one screw holding that first module on to get them out of the way, unplugged the cable, unscrewed the three screws holding the whole unit on and pulled it out, and then installed in reverse order. My complete assembly also had the fiberglass gasket like the original (instead of silicone). My tip was to use 3 little dabs of bearing grease just to hold the fiberglass gasket in place until I got the motor in place...and then use a dab of grease on the screw head to hold the screw in the socket so it wouldn't fall out. The whole thing too me 15 minutes including getting my tools and cleaning up. Thanks again for the great content!

[@davidrod1969]

thanks for the video, it gave me the confidence to replace the draft inducer motor myself. A local HVAC company wants to charge me $1499 to replace it. They also said that it was the last motor available in the whole united states. I found the motor on Amazon for $63.95 and the draft inducer blower wheel for $30

[@tsmurray1967]

Great video. After ordering the parts for my carrier weathermaker8000, it took me longer to drive to Lowe’s to get the sealant than it did for the actual install. Thanks so much!

[@davidrod1969]

which sealant did you use?

[@daviddobuzinsky3803]

Found all parts at repair clinic, $90 for motor.. It took me 1 hour to change. Penetrating oil worked for the set screw. Took apart motor and found the bearing close to the high temp was bad. I ordered a generic bearing on amazon for less than $5. I moved the okay bearing to the hot side. I will use the new non high temp bearing on the cool side. This is for backup. The bearing size is .865 OD and .3125 ID . Great video,Thanks.

[@yumis5244]

Thanks for this! Inducer motor was finally making some really weird sounds tonight. Luckily I had an inducer motor purchased 9 months ago from the local Amre Supply. Changed the motor tonight starting just before bed: 11:30pm to 2:15am (2h 45min). I used a bit of WD-40 to losen the hex screw on the inside fan. And the longest part was getting that hex screw out and shaft out to reuse the blower. Some tips: Tip 1: Use the hack saw if you have one. Tip 2: Reuse the inducer fan on the inside if you can. Try not to bend the hub. If you do, when you put it back on try and straighten it so it spins evenly. Tip 3: If you don't have a hack saw, turn a long socket upside down, and hammer on the shaft to push it through. I hack-sawed, but still needed to get the shaft out, and the socket, hammer and a long philips bit did the trick Tip 4: Have emotional support. Thanks TecnoMack! This helped a lot, and gave me confidence to do this myself. Next up...buy a spare blower motor, and see when that fails.

[@yumis5244]

One more tip, which is the seal. I had a two-layer fibreglass seal in mine. I think the seal is vital to have to keep the carbon monoxide vented. You might consider a CO2 monitor just outside the furnace room.

[@KosMos365]

Thank you! Have exactly the same furnace and had exactly same issue and zero experience with furnace repair. Following this video was able to easily fix it.

[@hermit3400]

Great video! Well done and well explained!! Video quality is amazing. After 25 years,I had to repair mine as the bearing ceased on the cage-fan side of the motor. Rather that buying a whole new motor, I just changed out the two NSK 608Z bearings. It was tough to get that cage fan off. Fortunately I have an acetylene torch and I had to heat the rusty hub up to orange hot to loosen the set screw, and then heat it up to orange hot again to get the hub to come off the shaft. I first tried with a hand held propane torch, but could not get it hot enough to loosen the set screw. After I got it apart I cleaned up the shaft and the hub with 600 emery cloth and it went back together nicely. Cost of the repair was under $20 CDN. Fortunately shaded pole motors draw the same amount of current when locked up, as when running, so the windings did not get burn up and shorted out.

[@TheTechnoMack]

Thanks for sharing your experience. I'm glad you benefited from the video. I'm sure your detailed comments will help other DIY-ers!

[@Vinlyguyx420x]

Super helpful and easy to follow video and I ended up doing it myself. I hit a few snags along the way, my motor was a slightly different model than the one in the video so my advice for anyone who wants to tackle this job with the help of TheTechnoMack's video is follow and listen to the video but just double check the motor matches the electrical connections. Maybe even bring in the old motor to the supply store to make extra sure. I had to go back to the supply store twice but the fan and the wheel fit both types of motors. I could not have done it without this video. THANK YOU!!!

[@jwbaker]

Thanks for sharing this video. It is very clear and helpful. It is particularly helpful in illustrating that nobody should buy this brand of furnace under any circumstances. It contains a subassembly that will need replacement several times over the life of the furnace, but is a massive pain in the neck to replace.

[@mauricewright9887]

Awesome tutorial. I don't know how long it would have taken for me to remove the assembly without this video. I probably would have had the property owner do it, which could have taken weeks. Weeks without a furnace is no bueno.THANK YOU!

[@dkapinus]

Thank you for this video! My Carrier furnace's inducer motor was making the same noise. I had intended to call my HVAC guy to fix it, but after stumbling upon your video I decided I could fix it myself. It took me about 40 minutes for the entire repair. I've read that most of the time HVAC repair companies will opt to use the $300 motor repair kit, which is a preassembled ready-to-mount unit that includes the motor and both fans mounted on a new bracket. Therefore, this DIY job is a huge savings on parts and labor!

[@TheTechnoMack]

Awesome. Happy I could help!

[@robertclymer6948]

My Carrier 58hdx060-12 high effeciency is nothing but trouble. Only 11 yrs old and have to replace the inducer assly 4 times. Original one, replaced that under warranty, another one 2 1/2 yrs ago and a new one last week. I kept the removed one and replaced both motor shaft bearings. Also had to replace the blower motor and fan last January for $536. Carrier is a POS in my opinion. In the future, I will do this all myself, thanks to guys like "The techno Mack" guy.

[@7pb77]

I was able to remove the slotted washer, that holds the fan wheel in place, with two paint can opener tools. I could reach behind the washer with the two paint can openers, and simply pulled the washer off from the shaft effortlessly within a couple of seconds. The fan wheel slid off the shaft undamaged. Hope this idea helps you when you pull off the fan wheel from the shaft.

[@TheTechnoMack]

Smart! Thanks for sharing!

[@michaeltrinidad1217]

I would buy the whole entire unit and save a lot of time.

[@skytab100]

Four Seasons HVAC in Chicago quoted me $959 to change this part! You saved me about $850. That is if the operation is successful TBD - thank you 😁 I ordered the new motor, wheel and fan per your recommendations.

[@thomm999]

Thanks for making this. I was able to remove the assembly and oil the bearings to get it working while ordering the replacement. Your video make this very easy and it's very appreciated.

[@carolinenikita]

Thank you for making this video. I followed your steps /directions exactly and got my furnace working. Bryant Gas Furnace. Only difference was i used the inducer housing gasket instead of silicone sealant.

[@madmanaenewman]

To remove the inducer fan I simply grabbed the push on nut (or whatever it is called) and twisted it off by turning anti clockwise (got that tip from the internet)...worked like a charm and saved me $39 CDN for that part. My Allen key was also rusted, but I just put the other end of the shaft in a bench vise and drilled out the shaft, placing the hole away slightly from the Allen key. Once the hole in the shaft was almost touching the shoulder of the blower wheel I was able to twist the blower wheel off, again very easy now that the shaft was hollow and had a very thin wall. With the blower wheel off and a bit of help from WD40 the Allen key loosened quite easily...another $51 saved.

[@TheTechnoMack]

That's awesome Jules. Thanks for commenting!

[@joeamith838]

Thanks, you are the man!!! followed your directions step by step and in the span of one half of the Minn/Carolina game it was done.subscribed!

[@boba6776]

Very good video on a problem that just came up on my Carrier gas furnace. With the weather here at 1 degree I was successful in quieting the screeching motor by dropping some silicone oil on the motor shaft just between the inducer fan and the motor and apparently enough oil got to the right place to stop the noise. I just did this as a temporary fix while I order the parts and replace the Inducer assembly when it gets a bit warmer. Thank you for the help, Bob

[@jimdiane100]

Did you have to remove it all to oil the shaft or were you able to reach while it was still assembled?

[@boba6776]

It was assembled and is still running without the squealing. I hope to get the parts locally on Monday and as I said it was just a temporary fix. Make sure the furnace is turned off if you try this. Bob

[@jimdiane100]

thanx @@boba6776

[@firstaid4film]

I oil mine yearly. I just drip the oil in the area of the front and rear bearings

[@MichaelRae]

Well done! Thank you. I watch a lot of how to video's and your teaching style is right at the top! I hate dealing with mission critical systems like HVAC without knowing exactly what I am getting myself into. Now I am wondering why I didn't do this early in the winter, instead of right now (April) when it will not be used for several months. :)

[@samk7717]

Very detailed and nice explained video. Exactly what I needed. Thank you

[@dianaionescu1153]

Thank you so much: efefctive and to the point! I do have a question: if you use silicone sealant, wouldn't be difficult to remove the assembly next time when you replace it? I guess by then, the furnace needs replacement anyways. All the best!

Applying high heat antiseize to the wheel shaft and set screw would be beneficial the next time you need to replace the motor.

[@cecilleflowerfarm]

Very helpful I will fix mine as soon the parts comes in.

[@snookerhand]

Very good clear instructional tutorial. My first of this kind. My Carrier furnace is short. Parker Pearce (hvac co.) came and charged me $342 for diagnostic without repairing any parts. Later, they said they could not further help me, because they said the part was discontinued. I was very depressed. I couldn't afford a new furnace and didn't know how to solve my heating amenity. I spent some time percolating about the problem and brooding. This last month of fall, the house was without heat. I wonder if you can help me. I believe my 2004 furnace is in the same family model (58CTA070-10112, serial 250 4A26011) as shown in your tutorial. Do I need different parts or, are the parts interchangeable? If so, I think I can follow your directions to the "T." Help!

[@tasadaqvirk5453]

Thanks for sharing this i have a same problem so i order all 3 parts from amre supply in $295 . now waiting for the parts to arrive...

[@dewrus2153]

That is a bit pricey for individual parts. I just ordered a complete assembly on Amazon for just $317. It's worth $22 to just remove the old assembly and install the new one without having to disassemble anything. The one I ordered is genuine Carrier.

[@Ann-fn8fp]

that's definitely pricey - I just ordered the whole kit for $200: www.northamericahvac.com/oem-carrier-bryant-payne-inducer-exhaust-motor-326628-761-3266828-701-326628-711/

[@lanad.4647]

You should've just unscrewed the three smalls screws-- not the brommet screws while working inside the furnace. The entire assembly can be removed without taking off the brommets. It's a lot easier to open up when outside of the furnace.

[@zbigniewwroniewicz]

Hi, I just bought all replacement parts and noticed that the mounting holes of the inducer motor are not threaded. Are the screws self tapping.?

[@zmanoman]

Great video. Thanks. Question... when you were taking out the assembly it was a 2 step process (unscrewing inducer motor then unscrewing fly wheel). Couldn't you have just unscrewed the fly wheel with the inducer motor intact? I'm asking because I'm putting in a used assembly with both already intact. Thanks.

[@pmc703]

The step wasn't necessary. He said he disconnected the motor to demonstrate the flywheel was too big to fit through the opening. He skipped that step during reassembly.

[@nickblack1036]

Thank you for taking the time to record and post this. It answered all of the questions I had, and ever a few I hadn't thought to ask. ;-)

[@never2be07]

Does this motor cover all the carrier furnaces? Mine looks just like that!

[@Ann-fn8fp]

If you go to the following link, it will tell you on the bottom of the page exactly which model number furnaces it will fit (there are a lot!): www.northamericahvac.com/oem-carrier-bryant-payne-inducer-exhaust-motor-326628-761-3266828-701-326628-711/ I just bought mine today and will be replacing the whole thing once it arrives. Our current one is making all kinds of squealing noises (the bearings going bad). I didn't feel like taking the thing apart so spent the $200 for the whole kit. This way, too, I know that the whole thing is new and ready to go.

[@jimfitzpatrick1693]

The part no. for the proper OEM Gasket Kit is: 320887-751, contains 5 items. Just Google it. The price will vary ($18-40 USD) depending on where you buy it from. The kit is made for many furnace repairs, only the larger gasket and the spindle pad are the only 2x items you will probably use (the smaller gasket and other items are not needed, depending on your Carrier furnace). There is small gasket kit that sells for about $10, but the gasket is too small (4"?).

[@Matt1075]

Great video...I am finding the entire assembly on line for about $350 (with out really shopping around ), meaning you dont have to mess with cutting the shaft to get the mounting plates off. Did you find it much cheaper to buy the individual parts as opposed to the entire assembly? It is absurd that HVAC company wants to charge 200 dollars for install.

[@anthonys.6038]

You didn't need to remove the first three bolts (grommet). You made that much harder than it needed to be.

[@swiftni]

that furnace is the same as mine but the inducer motor has no power

[@omranel-khatib4117]

Your parts replaced say HC21ZE125 but link says its only interchangeable with the HC21ZE114A. The 125 is 3x the price. Is this just con-marketing or would you recommend getting the 125?

[@TheTechnoMack]

If you have the same Weathermaker 8000TS, I can only ensure the HC21ZE125 will work. You may want to call a local HVAC company to check compatibility or maybe they can sell you the 125 for less. I'll investigate and update or remove the link as appropriate. Sorry for the confusion.

[@df56gh4d5h]

Couldn't you have reused the inducer wheel?

[@TheTechnoMack]

I could have if I were able to remove it from the spindle. It was fused on there, so I had to cut it off and replace it.
