How to Troubleshoot & Replace Whirlpool AP4294048 / Y303836 Dryer Blower Wheel Assembly

The bearing was wollered out. Tried repairing it several times. Should have gotten a replacement first thing. Perfect match and works great. Thank you 

Replaced the blower wheel broken at the hub. Also refreshed the dryer with new belt, clip & rollers. 

Went to Youtube to see if I could find a video of a dryer with similar issues. Knew that it probably needed a new belt but until I took it apart I wouldn't know the full extent of the worn-out parts. AppliancePartsPros definitely has the best, simplest, most accurate, information out there. Upon taking the machine apart and looking at each of the potential problems. It became obvious that the idler pulley was the real noise culprit. Replaced the blower wheel and the belt as well. All are really simple, take the worn-out piece off and put the new one on. Along the way, I cleaned all the lint and dust build-up. Removed and cleaned the drum support rollers. The side/bottom of the lint trap was packed solid, air was still flowing but it works a lot better now. Dryer is now very quiet. Ordered my parts on a Sunday and had them on Tuesday. What more can you ask! 

Replaced the Idler Pulley Arm and Pulley Wheel, then Tumbler Glides, and also the Blower Wheel. This was my first time taking on this job. So I took my time, it probably took me longer than others to do this but I got it done. And the dryer purrs like a kitten now and I hope that is good. And AppliancePartsPros.com was a big help! 

Purchased new part, and installed. Job went smoother then a fresh jar of Skippy. :-) 

Troubleshoot. determined blower wheel was broken. Ordered a new blower wheel, had it in two days. Put it on and good to go. 

I bought multiple parts that could have caused a noise, added a belt, and installed them all satisfactorily. Website and Customer Service are excellent. 

Replaced it. The dryer is 28 years old. The good old Maytag, that doesn’t have a million parts to break??. Meant to last. Was told by one local dealer that the part we needed was no longer made. They were wrong, weren’t they! 

Removed the front of the dryer and moved door wiring out of the way . Removed blower housing cover. Then removed the front snap ring and retaining ring from around the blower wheel. Plastic was busted off part of the wheel and the hole was stretched out of shape. The rear snap ring had come out of the groove on the shaft and had to be replaced. Replaced wheel and retaining ring and installed snap ring. Replaced the blower housing, wires, and front door. No more noisy dryer. 

Disassembly and inspection found one thermal sensor with burnt leads, the hub on the fan was broken, and the motor appeared frozen. Testing described in the service manual confirmed the motor was bad. Ordered the sensor, fan, motor, and belt. Some instructional videos show the top being left on, I took it off for better vision and reach. Fan install on motor was easier on bench top. Replacing the motor required wiring to a different connector than before, found a very good guide in these stories. Wires were all hooked up with motor in place but not fastened down, for ease of reach. Returning the drum and belt was much easier using a hint from a video: put the belt around the drum in the correct orientation (grooves facing OUT) then use it as a sling to help lift the drum into place. I used the back access panel to loop the belt around the gears. The rest of reassembly was straightforward. It took a while to do the repair mostly due to my uncertainty, and having to wait for parts that came in 3 separate shippings. Needed retaining clip pliers and strip & crimp tool for wiring.
