If you replaced your start switch, and that did not do it, it will be the microcomputer board, that is located behind the control panel. Part # AP6015193. Tom

This dryer uses a cheap power relay that likes to fail and blow out the microcomputer.
Advise to replace both microcomputer AP6015193 and the relay AP6008555.
If you want to keep this dryer, suggest getting someone to install a surge protector in the breaker panel.

Are you referring to the motor relay or heater relay. They are the same part number. Thanks

They are interchangeable.
