How to Troubleshoot & Replace Frigidaire AP3866842 / 134587700 Control Thermistor

Replaced heating element, thermostat, control thermistor, and belt, ordered grease and greased bearing, so far so good. 

Replaced thermistor and problem fixed. 

Replaced outlet thermal fuse and control thermistor. 

I checked the causes or reasons why my dryer would not heat up and found APP ranked the possible reasons and parts needed, along with videos on how to replace. I bought Parts to repair the top 3 possible issues. I bought the top three because the prices were so reasonable. I received the parts in 1 day, followed the instructions and my dryer works like new! 

Searched online indicating the dryer problem and watched the Appliance Parts video for checking the electrical system. I found the problem areas and ordered the parts. The installation was easy after watching the video. Back to drying clothes again. Thanks. 

First, I want to thank AplliancePartsPro.com for their incredible customer service and parts warranty. I was able to get all the parts necessary to repair my unit. The wife is happy and I'm happy... 

I ordered a new element and all the thermostat/thermistor components. Opened the dryer and systematically replaced all the components. Since I had no idea which component was the problem, I replaced all. Dryer now works well. 

Changed out control panel. Very easy job, my only issue was forgetting to pull the dial and LCD display from the old control panel onto the new. Once I realized that, the swap was complete, and the dryer has been running full cycles ever since. 

I replaced the control board, the hardest part was mounting the control panel without keeping the push buttons from falling out. I also replaced the control thermistor and the thermal limiter. I also checked in the drum bearing which I replaced a couple of years ago. It was not a difficult repair and the repair videos from your website really helped. 

After troubleshooting with the documents found online for my dryer I discovered that the thermistor was out of tolerance and the heating element was broken in two places. Ordered parts from appliancepartspros.com, cleaned it all up and put it back together. Pretty easy process actually. Hardest part was putting it all back together. Needed an extra pair of hands for that.
