Dryer is only heating for the initial heat cycle. The ignitor glows as it should on the following cycles but no flame. I just replaced the flame sensor as it had a broken tab. Checked the Thermostat, got 00.4 ohm reading at 200 setting, that is correct for a good part right? Are my coils bad? How do I check those? One has two connections, the other has three? I do not see any other obvious sensors to check. Is there some hidden somewhere? Thanks in advance for the help.
