Sanyo Microwave display not working

If your Sanyo microwave display is not working, start by pressing every control-panel button. If the microwave buttons are unresponsive or respond incorrectly, 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 blank screen or dark clock display. If the display is partially working or missing segments, the display board is more commonly at fault. When the microwave screen is completely blank, either the display board or main control board could be defective. Also confirm the microwave is plugged in, test the wall receptacle with another small appliance, and check the circuit breaker for an incoming power problem. A faulty control board can also prevent the digital display from working when the board has power. Enter your Sanyo microwave model number to find the exact replacement control module, touchpad, control panel, main control board, or display board 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 the microwave is unplugged. Proper capacitor discharge is required before interior work, and a qualified technician may be needed if you are not familiar with that procedure.

01 - Sanyo 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.
Highly Likely

06 - Sanyo 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.
