RCA Microwave display not working

An RCA microwave display not working can result from a failed control module, touchpad, control panel, main control board, or display board. First, press each control-panel button. If the microwave buttons are unresponsive or none respond correctly, the control module is the most likely cause and may need replacement. If your model does not use a separate display board, a defective touchpad and control panel can cause the blank screen. When the display is partially missing, such as missing segments, the display board is more commonly at fault. If the microwave screen is completely blank, either the main control board or display board may have failed. Also confirm the microwave has incoming power by testing the wall receptacle with another appliance and checking the circuit breaker. A control board with power but no working display may need replacement. Enter your RCA microwave model number to find the exact replacement part for your appliance. Any repair that requires opening the outer cabinet must be handled carefully because the high-voltage capacitor can store a lethal charge even after unplugging. It must be properly discharged before interior work, and a qualified technician should perform the repair if you are not familiar with capacitor discharge procedures.

01 - RCA 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.

06 - RCA 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.
