Recently our dryer started having what seems to be a fairly common problem. The timer would not advance (when set to one of the heating modes), and there would be no heat. This problem seems to be somewhat intermittent.

Today I disassembled the dryer and tested the components with a multimeter:

The solenoid coils measured ~1.2k/1.3k/500 as I believe they are supposed to
The low side of the coils showed continuity (when powered off) to the "timer" side of the two thermostats (both the control and the high limit, in series).

I ran the dryer (with heat) with the front panel off, and saw the ignitor glow, and the gas turn on.

I've checked the ducts, and we seem to have good airflow.

Based on the above, my best guess is that the control thermostat is not regulating the temperature correctly, causing the high limit thermostat to shut down the heat. Would this also possibly cause the timer to stop advancing?

Replacing the control thermostat is easy enough, but I'd like to avoid buying a new one until I'm somewhat confident that it's the culprit.

Any advice would be most appreciated.
