Universal Microwave display not working

Is your Universal microwave display not working? The control module is the most likely cause, especially when the control panel buttons are also unresponsive. If your microwave does not use a separate display board, a defective touchpad and control panel can cause the same problem. A display that is partially blank or missing segments more commonly points to a faulty display board, while a display that is completely dark may involve the main control board or display board. Before replacing parts, confirm the microwave is plugged in, test the wall receptacle with another appliance, and check for a tripped circuit breaker. If the control board has power but the digital display remains off, the control board may need replacement. Enter your model number to find the exact replacement control module, touchpad, main control board, or display board for your specific microwave. Any repair that requires opening the outer cabinet must be handled carefully. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged, so it must be properly discharged before interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician perform the repair.

01 - Universal Microwave Control Module

A malfunctioning display could be caused by a defective control module. Try pressing each of the buttons on the control panel. If none of the buttons are responding correctly, it is likely the control module is defective and will need to be replaced.

05 - 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.

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.
