Samsung Microwave Error Code E-23 — Preheating Time Error (Convection Models)
What this means
The E-23 error code appears on Samsung microwaves with convection oven functionality. It indicates the oven cooking temperature could not reach the desired preheat setting within 30 minutes. This can be caused by a faulty convection heating element, a defective convection fan motor, a failed temperature sensor, or the microwave operating in an unusually cold environment.
Alternate codes: E23
Step-by-step fix
2 stepsReset and retry
Unplug the microwave for 60 seconds, plug it back in, and try preheating again.
Ensure the room temperature is above 60°F for proper convection preheating.
Listen for the convection fan
When using convection mode, you should hear the convection fan running. If the fan is not running, the heating element alone cannot distribute heat effectively.
A non-running fan during convection mode typically means the fan motor has failed.
When to call a professional
Testing and replacing the convection heating element, fan motor, or temperature sensor requires disassembly of the microwave near high-voltage components. Professional service is required.
