E-Wave Microwave display not working

When your E-Wave microwave display is not working, start by checking whether the control panel buttons respond. When the microwave screen is blank, clock display is not working, or buttons are unresponsive, a defective control module is the most likely cause. If your model does not use a separate display, the touchpad and control panel may be faulty. A display with missing segments or partial numbers more commonly points to a failed display board, while a completely dark display can result from the main control board or display board. Next, confirm the microwave has power by testing the wall receptacle with another appliance and checking the circuit breaker. If the board has power but the display remains off, the control board may need replacement. Enter your E-Wave microwave model number to find the exact replacement control module, touchpad, main control board, display board, or control board for your appliance. 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, use a qualified technician.

01 - E-Wave 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.
