The dryer turns on and tumbles but produces no heat. The ignitor glows and stays hot but the burner never ignites. I have tested and have continuity on the thermal fuse and the high limit thermostat. There is no continuity on the thermistor. Is the thermistor defective? Thanks for any help. Bill

Hi Bill,

The first failure suspect is a bad gas valve coils.

- The coil kit Part number: AP2150379

Hi Gene,

I checked the coils for continuity and they both have it. I suspect that I may have a bad flame sensor. The ignitor glows hot and just keeps glowing, but no ignition of the burner.

If the igniter glows nonstop then the flame sensor is bad.

Presence of continuity does not prove the coils are good. They have to have specific resistance - http://forum.appliancepartspros...er-runs-but-no-heat.html.
