Panasonic Microwave display not working

If your Panasonic microwave display is not working, first confirm the microwave is plugged in and the wall receptacle has power by testing it with another small appliance. If power is available, a defective control module is the most likely cause, especially when the microwave screen is blank and none of the control panel buttons respond correctly. On models without a separate display board, the touchpad and control panel may be defective instead. If the display is dark only in sections or has missing segments, the display board is more commonly at fault. A completely blank clock display can also result from a failed main control board, particularly when the board has power but the display does not. Before replacing parts, enter your model number to find the exact Panasonic replacement part for your specific microwave. Any repair that requires removing 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 begins, and this repair may require a qualified technician if you are not familiar with safe capacitor discharge procedures.

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.
Highly Likely

06 - Panasonic Microwave Control Board

Since the control board is a part of the digital display, a defective board could be responsible for a microwave display not working, if the control board has power to it but the display is not working replace the control board.

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.
