How to Troubleshoot & Replace Whirlpool AP6008294 / WP338906 Flame Sensor

We went to Applianceparts.com and found the parts that could be wrong, ordered them, and installed them ourselves. Still cheaper than calling the repair guys. They charge a fee then tell you what parts you need. If you want them to come back and install there is another fee. 

At first the dryer wouldn’t dry the clothes, not enough heat. So I researched on google and found this AppliancePartsPros website where it suggested I replace the gas valve solenoids as the number 1 reason. So I ordered the parts and replaced according to the great AppliancePartsPros video. That solved the problem for about two weeks. Again, no heat, no gas, no flame three weeks later. I again researched on google what could be causing no heat, no flame, and no gas to come through. Then I found out that the thermal sensor (thermostat) failed through another homeowners video on YouTube. I ordered the parts through AppliancePartsPros and this time I replaced all of the sensors and fuses rather than wait for them to fail since I had the whole dryer taken apart (thanks to AppliancePartsPros for showing how to replace thermal fuses and tear apart and put back together a gas dryer, the same model I had!). 

I replaced the heat sensor, but found that was not the problem . A bird had built a nest in the exhaust vent & caused the sensor to register a false reading . Cleaned the vent and working nicely now thank you . 

Had to open top, remove front panel, remove drum and belt. Used meter to check and replace flame sensor. 

I installed a new flame senor through the inspection access. little awkward but it took about 10 minutes. to me seemed easier than dragging the dryer out to more open space, and disassembling and such and stuff. 

Bought these 5 parts, installed and it works perfectly. I bought all 5 so I wasn't wasting time. I could've maybe narrowed it down to the culprit, but I just got all 5 since it's so old. Fast delivery quality parts. Happy wife! 

The Videos for the repairs were very helpful. Parts were in stock. Very easy to order. works great Thanks you 

Bought a dryer repair kit, with rollers and belt, plus hot surface ignitor, flame sensor, limit switches, and coils for gas valve. The tutorial video for the rollers and belt was excellent. Really made the job easy. 

My Maytag gas dryer kept at a low heat, similar to being on the "Delicate Cycle". All sensors and thermostats tested ok with the multimeter. Most solutions suggested online were other parts. I had a feeling the flame should have been bigger after ignition, but did not witness in the past my dryer during normal operation. The solenoid coils did not change the symptom. I found a schematic of my dryer and what parts interacted with one another. In addition, I combed the internet to find how the gas valve was constructed...since there are 2 coils. Once I found the valve diagram, I realized that there could be a chance there wasn't enough gas being fed through the valve(s). Well, the replacement of the gas valve was the fix! I know it's a rare occurrence, but now I know the proper size of how the flame should look. It sure saves on buying a new dryer!!!
