The dryer has worked for several years without a problem. But suddenly, without warning it won't start. There is no sound or action.

I have checked the:
Push to start switch
Door switch
Thermostat
Thermo cutoff switch
Thermal fuse
Timer (This I only checked for continuity when set at 60 minutes. This area also contains a small board.)

The input voltages are OK up to the Push to Start switch. The rest I checked for continuity.

What other hints would you have?Is there any kind of reset switch anywhere?
Thanks,
Fairfield
