E23 reports that the oven did not reach preheat temperature in thirty minutes; the heater, control board or wiring may be involved.
Model compatibility: KitchenAid reuses codes across series and model years, so E23 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Preheat temperature was not reached within thirty minutes; possible heater, appliance control board or wiring problem.
What E23 reports
Thirty minutes is the figure in KitchenAid’s description of E23: a microwave with an oven function did not reach preheat temperature within thirty minutes. The cavity was waiting to get hot and did not.
Possible causes named
The article marks each of these as something that “may be a problem”:
The heater, which is meant to bring the cavity up to temperature.
The appliance control board, the electronics running the oven.
The wiring that links the two.
It does not identify a usual culprit and offers no way for an owner to tell the three apart. That sorting belongs to a technician.
Reset from the article
Switch the microwave’s breaker off at the panel and wait one full minute.
Switch it on again.
Remain nearby for one more minute, looking for E23.
Run the oven to make sure it behaves normally.
A code that stays gone needs nothing further. If it appears again, the article’s next step is service.
