How to Troubleshoot & Replace Whirlpool AP6008294 / WP338906 Flame Sensor

Parts 

A 20 year old dryer that keeps chugging along. Thought it was the thermal fuse but it wasn't. Decided to replace what I could related to heating. Decided it was easier opening it once then multiple times. Works great now. Good for a few more years. The videos are awesome! 

Thermostat, coils, ignitor, sensor, and valve 

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 the flame sensor, valves, and thermostat 

Replaced the parts purchased based on Appliance Parts Pros site recommendations saying these are the most common culprits. Their video was also helpful in doing the repair. Overall, easy repair to take apart the dryer and put back together. 

I have an old Kennemore dryer (110.79422800) that came with the house (no idea how much use it had w previous owners) and used it for a couple years before it gradually took longer and longer to dry, eventually lost the ability to use heat, and if I tried to use one of the heat settings, the timer didn’t advance. I am not an experienced handyman by any means, but read enough reviews to see that the parts that go out on these gas dryers are: the gas valve coils, flame sensor, and dryer igniter. They were all parts that required the same (dis)assembly so I ordered them all. I did generally feel more comfortable with certified OEM parts, and the return policy from AP. The videos all did a great job of showing the repairs, including things to look out for. That plus the fact that the tools-needed were minimal, gave me the confidence needed to do all the replacements myself relatively frustration-free. Sure enough the dryer works again now, so the $ I spent on parts (even without knowing which was the real culprit) and minimal time for the replacement was well worth it considering the alternative was to look at new dryers. 

There were several parts that could have apparently caused the issue. So instead of doing one at a time I just replaced them all at once. Much easier that way since taking the machine apart is the hardest part of the job. Problem solved.

Was not sure what the exact part it was but went ahead and changed flame sensor and gas valve coil kit
