How to Troubleshoot & Replace Whirlpool AP6008273 / WP3387223 Dryer Moisture Sensor Bar

Replaced the thermistor and moisture sensors. Followed the video instructions on their website which were very easy to do. My dryer now works like new. It save me several thousand dollars as I was ready to buy a new one. 

Replaced the moisture sensors. 

Our dryer sound like it was going to blow up and I figured It was having an issue with the belt. I Googled our dryer model # and found Appliance Parts Pros. Appliance Parts Pros offered a kit to replace all worn parts and a video to assist with the replacement. I ordered the parts and they arrived quickly. I used the video and a helpful call to customer service to assist with completing the replacement. Two hours later my dryer runs like new and my wife was amazed how much better the dryer is operating. Thank you so much and I would recommend more people look to perform these repairs because it really was not the difficult. 

NOTICE: If using this kit for Maytag MGBD400QV0 - Belt is not the right one. if possibly use your old one. Everything else worked fine. The chirp was undoubtedly caused by a frozen idler wheel. Had to work to get it off the shaft. Took a while to clean up the shaft but finally got the idler wheel on and it spun freely. Now the belt was a problem. I assumed the new belt was a correct replacement and after assembling everything the dryer would power up but not spin. After several hours looking for possible remedy I decided to check the thermal fuse (continuity ok), the thermistor (11k ohms ok), and the idler shaft micro switch (ok). It dawned on me that I might be putting the belt on wrong. But for the life of me I could not get the belt on right. Fortunately, I had not discarded the old belt so I compared the two. New belt was shorter (1-2") and not as wide. Once I tried the old belt, which appeared to be in excellent condition, I was able to easily install it. Problem solved and dryer runs like a top with no chirping. 

Replaced moisture sensors. Easy, about a five minute fix although while apart, took a few minutes to vacuum out lint that I could see inside machine. 

Dryer thermistor AS SUGGESTED by the website. 

Replaced the moisture sensor bars, which was easy to do. It took me about 15 minutes. 

Ordered and replaced all sensors parts. Leveraged your video and another video. Took less than 3.5 hours. Tested it. It worked. 

Replaced the moisture sensor bars as they are getting old and the dryness level doesn't quite seem right sometimes. The video on appliance parts pros made it super easy! Genuine OEM parts. 

New heating element, thermostats, and sensor bar.
