Thanks for the wiring diagram and for your fast response.
The timer works when in timed mode but not in high heat or low heat mode. But, when in timed mode the timer will stop working just after the first click is heard on the timer. If that makes sense. Also, when I say the timer is working, I'm going by the "site glass" in the timer itself. The dryer will not shut off unless I manually turn the knob to the off position.
