How to Troubleshoot & Replace Whirlpool AP4043265 / 33001790 Blower Wheel

After watching a few videos, I opened the front of the dryer, removed the old pieces and put in the new ones. This model of dryer was pretty easy to work with. One thing that I didn't expect to be so difficult was the removal of the old blower wheel. The new one slid right on, but the old one didn't want to budge without a lot of force. If you can go ahead and get the special snap ring pliers, it would definitely make it easier to get the snap ring off and on, but I did the repair with a set of tweezers. I recommend wearing work gloves--I got a few nicks on my hands while doing the repair. 

Inspected inside of dryer parts and saw that the dryer blower wheel was cracked. Called a major department store to order part and was told it would take almost 2 weeks to be delivered to the store. I looked the part up on line and found AppliancePartsPros.com. I ordered the part on line on Tuesday and it was delivered to my door on Thursday! It also cost me less than it would of if ordering it through the store including shipping and handing. Luckily I have a handy son in law who was able to do the repair and my dryer sounds like new even though it is over 10 years old and for a total cost of $26.92! I would definitely recommend this site for its reasonable prices, ease of placing an order, and fast delivery and would not hesitate to contact AppliancePartsPros again if a need arises in the future Very Satisfied Customer 

After reviewing your website for possible causes, and disassemble procedures, I disassembled the dryer unit. I found a lot of dirt but, also found a bad guide wheel that support the drum, the bearing in on the motor unit were leaking oil, and the blower wheel D shaft was worn out of shape causing the wheel to hit the housing. Also the original belt had air checking cracks which made sense to replace it. I decided to replace the thermostat per your website recommendation for solving over- heating. The felt seal on the front of the drum was damaged so I included a replacement in my order and installed a new seal. After receiving all of the necessary parts I performed the reassembly of the unit. After installing all of the parts I did a trial run and the belt jumped off the motor axle. After some fun reinstalling the belt properly I test ran the unit. Whoa it sounds like new. Oh but then a slight rattle noise started, I suspect because I did not replace the new drum roller axle that I purchased for the new drum roller. The noise seems to have decreased after multiple cycles, but I plan on disassembling the unit and installing the part. Over all the dryer is working like new, including the over heating issue seems to be solved too. Thank you for the great source of parts and installation videos. In the past I have also repaired my neptune washing machine multiple times using parts from AppliancePartsPro.com 

Both parts were replaced, which took approximately 1 hour. 

Opened dryer to gain access to broken blower wheel, and replaced it. 

Spoke with appliance parts and troubleshooting from their video ordered new coil for igniter. 

Disassembled the dryer and inspected it…Found the blower wheel broken and had been rubbing on the plastic housing. Clean out housing and vent, and replaced the wheel. Inspected the felt seal on the drum, it was replaced 2 years ago when I replaced the rollers and belt. Inspected burner and cleaned out lint and debris. Before installing the door, checked the operation and all is good, installed door. 

I replaced the motor and a belt. 

Put a new one in. 

I had already broken down (took apart) my dryer one other time to replace some parts and did this again to install a new blower wheel fan and the repairs/replacement went well knowing full well that when I had the dryer apart last time around and knew of the slight break in the old blower wheel--I should of ordered a new part for this then!!!
