Modern Maid Microwave display not working

When a Modern Maid microwave display is not working, start by pressing every control-panel button. If the microwave buttons are also unresponsive, a defective control module is the most likely cause. On models without a separate display board, the touchpad and control panel may be responsible for a microwave screen that is blank or dark. If the display is missing segments or only part of it is out, the display board is more commonly at fault. A display that is completely dead can result from either the display board or the main control board. Also confirm the microwave is plugged in and the wall receptacle has power, then check whether a circuit breaker has tripped. If the control board has power but the digital display still does not work, replace the control board. Enter your model number to find the exact Modern Maid replacement part for your microwave. Any repair that requires opening the outer cabinet must be handled carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. The capacitor must be properly discharged before interior work, so use a qualified technician if you are not familiar with the procedure.

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.

07 - 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.
