Error codeE-23
ApplianceMicrowave
Affected model seriesE30MH65GPSA, E30MH65GSSA
Quick answer
Electrolux microwave code E-23 indicates preheat did not reach the preset temperature within the expected time.
Model compatibility: Electrolux reuses codes across series and control generations, so E-23 may mean something different on another appliance or platform. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
If your Electrolux microwave displays E-23, the control has detected preheat did not reach the preset temperature within the expected time. Start with the checks that are safe to perform without opening the appliance. Use the observed symptoms and the full model number to confirm the correct diagnostic path.
For this control generation, the useful interpretation is specific: preheat did not reach the preset temperature within the expected time. Do not choose a replacement part from the display alone; convection heater problem and convection motor issue can produce overlapping symptoms.
This code set is documented for Electrolux over-the-range microwave models E30MH65GPSA and E30MH65GSSA. Do not apply these meanings to another microwave platform without model confirmation.

When to call a technician
A recurring E-23 convection code requires internal heater, motor, sensor, and control diagnosis.
Do not erase useful context with repeated resets. If E-23 returns, note whether preheat or convection cycle may cancel and provide the full model number so convection heater problem can be tested in the correct platform sequence.
