Error code E23
Appliance Microwave
Quick answer

E23 means the oven did not reach pre-heat temperature within 30 minutes.

What this code may mean.

A plain-language reading of the code — always confirm against your model’s documentation.

Pre-heat temperature not reached within 30 minutes.

The oven did not reach pre-heat temperature within 30 (thirty) minutes, and the microwave shows E23. There may be a problem with the Heater, the Appliance Control Board or the wiring.

Power reset

Turn the breaker off for one minute and back on. Watch for one minute to see whether E23 returns, then verify the microwave works.
