Dryer Circuit Diagnostic Checklist
Question: I am on my third electric dryer. First one we replaced because we were told the board was bad.

This question came from Kathleen, a Homeowner from Bellaire, Texas.

Dave’s Reply:
Thanks for your electrical question Kathleen.

Kathleen, The following are the electrical components that should be checked by a qualified electrician, or a qualified appliance service technician.

Dryer Circuit Diagnostic Checklist:
1.) The dryer outlet – Look for loose or burnt wires.
2.) The circuit wiring – has the circuit wiring been damaged.
3.) The circuit breaker at the panel – the connections, internal contacts.
4.) The connection between the circuit breaker and the main buss of the panel

Turn off the main breaker, remove the dryer circuit breaker, inspect the contact surfaces between the circuit breaker and the main panel buss.

If the surface has been damaged then install a new breaker in a different position in the panel and install breaker blanks in place of the old breaker position.
