My Whirlpool Gas dryer, Model GGW9250PL0, is taking too long to dry clothes. Here are the symptoms:

- Dry cycle begins
- Ignightor lights
- Gas valves open
- Flame kicks on and runs for 5-10 minutes and cuts out
- No Flame for MANY minutes, but above steps may occur again during cycle
- Cycle completes, clothes still very damp
- Will require 3-4 cycles to get clothes dry

The coils were replaced about 3 months ago and all was fine. Symptoms are a bit different this time. When colis were bad, ignigtor would light, but no flame. Now, after the first cycle, ignigtor does not attempt to light.

I just replace the Thermistor and still have same problem. I also removed the exhaust vent and visually inspected it from inside outside. This is a very short run (approx 6-8 feet) and there is good airflow on outside during the dry cycle.

Not sure what to try next. Any ideas?

I was able to figure this out. Perhaps this post will help someone else.

The problem was with the Thermal Fuse. Probably more valuable is the lesson learned. This was an intermittant problem (dryer started off working but then would fail). When testing electrical components, it pays to test, double check and triple check every part both when cold and after the appliance has heated up and started to fail.

If you want to know the boring details, feel free to read on. Initial tests showed very slight resistance on Thermal Fuse (approx 2-3) but did show approx 30 for the Thermistor. After changing Thermistor did not work, and oh btw, both the old and the new Thermistor showed same resistance, I continued testing EVERY component. All checked out well. After continuing to run appliance and testing EVERY component, the Thermal fuse started showing more resistance in the 14-15 range. Volia ! Changed Thermal Fuse, all is now well.
