Microwave keypad beeps but display does not change or accept input (e.g., cannot set time).

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Microcontroller glitch on control board, Partial keypad failure, Child lock or demo mode active, Corrupted control firmware

Safety first: Unplug the microwave before extended resets.

Check for lock/demo mode: Refer to the user manual to ensure the unit is not in demo mode or child lock. Disable these features if active.
Hard reset: Unplug the microwave for 10–15 minutes to fully discharge the control board. Plug back in and test.
Key sequence test: Try different keys (e.g., POWER LEVEL, CLOCK, STOP/CLEAR) to see if any functions respond.
Next step: If the issue persists, the control board may be failing and will likely need replacement.
