Error codeE23
ApplianceMicrowave
Why E23 appears
The oven on a Maytag over-the-range microwave has 30 minutes to reach its pre-heat temperature. Miss that window and E23 shows. Maytag lists the heater, the appliance control board and the connecting wiring as possible causes.
Power-cycle routine
Cut power at the breaker(s) for sixty seconds.
Put the breaker(s) back on.
Remain nearby for one minute and make sure E23 does not return.
Check that normal use is back.
If it shows again
Maytag says a qualified technician may be needed when E23 returns, so book that visit.

E13 describes a pre-heat failure too, with the control board and wiring in focus. E24 is the opposite problem, an overheat condition, and E22 is a shorted thermal sensor circuit.

Model compatibility: Maytag 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
The oven did not reach pre-heat temperature within 30 minutes; the heater, control board or wiring may be at fault.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
