Litton Microwave display not working

Is your Litton microwave display not working? First press each control-panel button. If the buttons are unresponsive or operating incorrectly, the control module is the most likely cause and may need replacement. On models without a separate display board, a defective touchpad and control panel can also cause a blank microwave screen or a clock display that is not working. If only some display segments are missing, the display board is more commonly at fault. If the display is completely dark, the main control board or display board may be defective. Also confirm the microwave is plugged in and the wall receptacle has power, then check for a tripped circuit breaker. If the control board has power but the display remains blank, the control board may need replacement. Enter your Litton microwave model number to find the exact replacement control module, touchpad, main control board, or display board for your appliance. Repairs that require opening the outer cabinet must be handled carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. It must be properly discharged before interior work, so use a qualified technician if you are unfamiliar with capacitor discharge procedures.

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.
