Residential Sharp Microwave Won't Start — Boonton ZIP 07082, NJ

Before calling a technician, check these basics: the outlet is working (try plugging in another device), the power cord is fully seated, the circuit breaker hasn't tripped, the door/lid is fully closed and latched, and the control lock or child lock isn't enabled. If all checks pass, call us.

If your dishwasher won't start, check that the door is fully latched (most won't run with the door slightly open), the child lock isn't enabled, the water supply valve is open, and the circuit breaker is not tripped. If all are fine, the cause is likely a faulty door switch, blown thermal fuse, or control board failure.
