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

Replaced the belt, pull wheel, four rollers and one roller shaft. Also replaced the drying sensor. Just under 4 hours from prep to clean up, taking my time, following the provided videos and instructions. 

I followed the instructions I learned on the YouTube video and had the part installed in about 20 minutes. 

Replaced moisture sensor bars. (Also replaced the door latch kit while I was at it.) 

I replaced most everything that had to do with making or regulating the heat in the dryer. It is a gas dryer setup for propane. I have had the dryer apart before to replace the thermistor and to unclog the water mister port, so it did not take me very long to disassemble the dryer to get to the parts I wanted to replace. This time I also replaced the belt and drum rollers since the unit is over 15 years old now. All together the repair took me 4 hours start to finish and cleanup. It would have been less time, but I also cleaned the fan rotor while I was in there and applied new seal material around the fan enclosure cover and the lint catcher because I was having some bypass. It was a lot better than forking out $900+ for a replacement that is not built as well. Works better than new now!!! 

Replaced both moisture sensor bars 

Replaced with part 

I replaced the sensor bar like your video said to do. Now the sensor works but the heating element isn't working. So that is the next thing to replace Thank you for your help. 

Dryer was still working but without heat, so we thought that the sensors must still be working but the heating element was not. Researching it on Appliance parts the sensors were a common failure so I decided if I was going to be taking it apart I was going to replace them as well. The videos made it easy and all replacements went smoothly, the heating element had failed and the coil had broken. After replacing the parts it was heating and working again. 

Replaced the 2 parts ordered. 

I watched a YouTube video. I cleaned out all of the lint and swapped out the heating coil. My 26 year old Kenmore dryer lives for another decade I hope!
