Caloric Microwave display not working

If your Caloric microwave display is not working, start by pressing every control panel button. If the buttons are also unresponsive, a defective control module is the most likely cause and may need replacement. On models without a separate display board, the touchpad and control panel can cause a microwave screen to go blank or the clock display to stop working. If only part of the display is missing, such as individual segments, the display board is more commonly at fault. A completely dark display can also result from a failed main control board, display board, or control board, provided the board is receiving power. Before replacing parts, confirm the microwave is plugged in and test the wall receptacle with another small appliance. Check the circuit breaker if there is no incoming power. Enter your Caloric microwave model number to find the exact replacement control module, touchpad, 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, and a qualified technician should perform the repair if you are not familiar with that procedure.

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 - Caloric 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.
