Common solutions for: Microwave display not working

01 - Display Board
If the display isn’t working at all, either the main control board or the display board could be at fault. If the display goes out partially, the display board is more commonly at fault.
Top Solution
02 - Incoming Power Problem
Confirm the microwave is plugged in and there is power at the wall receptacle. You can plug another small appliance into the receptacle to confirm there is power. If there is no power, confirm the circuit breaker has not tripped.
Highly Likely
03 - Power reset
A microwave display not working may be due to a power outage or power surge. Full operation can sometimes be restored through a power reset by either unplugging the unit's power cord for a few minutes and then plugging it back in or switching off the circuit breaker for the microwave then switching it back on.
