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

Ordered the part from Appliance Parts Pros and used their excellent repair video to swap out the old one for the new one. It was very easy. I have used Appliance Parts Pros for many years now to help keep my washer, drier, refrigerator, and dishwasher going. I trust them for the right parts and they have great tutorial videos. 

Replaced the blower wheel as instructed by how-to video and successfully resolved the issue. 

Using APPs videos and common sense. 

Initially, I ordered a set of drum rollers and bushings and a set of felt drum seals. I also ordered a drum belt since it had never been replaced. I followed the videos on your web site and replaced all the parts, reassembled the dryer and turned it on, but the noise was still present, though somewhat less than originally. One of the drum rollers was seized up and the rubber portion was hard and cracked. Thinking perhaps the drum had gotten bent, I opened the dryer back up, but everything was okay. I called my brother, who suggested I look at the motor shaft. He thought either the drive pulley or the blower fan might be loose on the shaft. The pulley was fine, tension was nice and tight, but when I disassembled the blower wheel housing, sure enough, the keyway inside the wheel was completely worn away. The wheel was turning freely on the shaft and inside the housing, causing the noise. I ordered the blower wheel assembly from Appliance Parts Pro, and it arrived the next day. I slid the blower wheel onto the shaft, attached the clamp, replaced the snap ring, and reassembled the dryer. When I turned it on, nothing but quiet. I ran several loads of clothes and everything dried beautifully -- and quickly. No telling how long the fan had been loose and not circulating air properly. 

I appreciated the overnight delivery of the correct part. 

So dryer got harder to start over time. I cleaned lint and junk out, helped a little. Did notice that I could move the drum by hand a little and it would start then. Replaced motor, belt and the fan. Replacement went fairly straightforward. There were no instructions with any parts and no diagram for rewiring the motor from the old style. The video on YouTube was good and helpful even though it wasn’t exactly the same as my dryer. Reassembly wasn’t bad. Getting the belt hooked without pulling the dryer out was somewhat difficult. All and it went well and would recommend. This was not my first purchase from APP and probably won’t be the last 

Ordered a replacement blower wheel and put it on. Good service and quick delivery, thanks. 

Replaced it. 

The blower wheel hub had worn through, and was shaking on the axle and hitting the sides. 

I watched some videos on possible problems and then started checking things. Nothing was terrible. Just lots of stuff not real great. After cleaning and checking everything, I ordered parts and started fixing stuff. I replaced the Drum Rollers, Drive Belt, Drive Belt Idler, Front Drum Glides, Front and Rear Drum Seals, and the Blower Wheel. I also had to rebuild the Idler Arm as the pivot hole was elongated. A little cut and weld with some careful filing and a new 'hole' was created. I also added a spacer washer to take up some extra play in the idler arm and made a sleeve to hold the outlet duct to the blower housing better. The end result is I hit the Start button, and the dryer sounds like its new again. Thanks for the videos, great parts, and quick shipping. Now on the the 30+ yo Maytag Washer...
