How to Troubleshoot & Replace Whirlpool AP6014731 / WPW10016550 Lower Blower Assembly

Replaced part. 

I followed your YouTube video to remove the wall oven and replace the part as directed. This fix saved me $3000 by not having to buy a new oven. Given the COVID-19 pandemic, no company wanted to repair the oven or install a new one. I’m thankful for your DIY videos and made the $100 part seem insignificant compared to what I could have spend to have others fix it. 

Watched a YouTube video and went at it. Took a while to figure it out, but after you've done it once it's not that hard. 

The first problem I was working on was that the Lower Blower was not turning so I opened the back of the oven and gave it a push. It started working but I knew that I would need to replace it. I reassembled the oven and realized that the oven wasn't heating. I got on the "Appliance Parts Pros" website and used their troubleshooting topics and videos and discovered what had failed (Thermal Fuse). I disassembled the oven again and tested the thermal fuse by placing a jumper across the fuse to prove the failure (the videos show you how to replace parts not how to test the parts for failure). I only used the jumper to prove the failure, I did not operate the oven with the jumper in place after the test was complete. I purchased the parts from "Appliance Parts Pros." they arrived 2 days later, I changed them out (they fit perfect!) and now my oven works great! 

Replaced the lower blower fan. Easy fix and the videos Appliance Parts Pros have been so perfect for every repair I take on. THANK YOU!! 

Replaced the lower blower (fan) which had developed worn bearings or bushings. Located oven drawing and replacement part online. Removed oven from wall cabinet and took off two back panels to access the blower. Loosened screws holding fan, disconnected two wires by slipping blade connectors off terminals. Installed replacement fan. 

I replaced the fan 

I replaced with quiet fans, tada. 

Replaced blower assembly. 

After doing some on line research I isolated the problem to the Blower Motor. The replacement is very easy. First remove the upwirght trim on the face of the oven, one screw on each and are located on the inside of the oven when the door is open. Next, remove the two cabinet screws that hold the oven to the cabinet. Lastly, remove the lower trim from the oven, two screws. Next, cut the power off to the oven and slide the oven out,this will take two people and have a surface ready to set the oven on.Next, remove the sheet metal top of the oven, it's in two pieces and then the back of the oven, all are secured with screws. Once you have the top and back off, you will see the blower motor. To make sure this was my problem part, I reset the breaker and turned the oven on for a moment to see the blower motor wasn't working. I then shut the power back off and started to remove the old blower unit. Remove the foam strip off the blower motor as it reveals two screws that need to be removed in order to free the blower for removal. Disconnet the two lead wires and remove the old blower. Reverse the steps outlined and your on the way to a quiet and efficent oven. I wished I would have done a video of the project so as to take the fear out of tackling this project.
