Whirlpool Microwave Error Code F1 E1 — Relay Control Board Failure
What this means
The F1 E1 error code on Whirlpool microwaves indicates a problem with the relay control board. This board houses the relays that switch power to the magnetron, turntable motor, lights, and exhaust fan. When it fails, the microwave may not heat, the turntable may not spin, or multiple functions may be affected simultaneously. Power surges are the most common cause.
Alternate codes: F1E1
Step-by-step fix
2 stepsPower cycle the microwave
Unplug the microwave (or turn off the breaker for a built-in/over-the-range unit) for 5 minutes. Restore power and check if the error clears.
If the microwave is hardwired, use the circuit breaker to disconnect power.
Seek professional repair
Microwave ovens contain a high-voltage capacitor that can hold a lethal charge even when unplugged. Do not open the microwave cabinet unless you are trained in microwave repair and know how to safely discharge the capacitor.
The capacitor can hold thousands of volts — this is not a typical DIY repair.
When to call a professional
Microwave internal repairs should always be performed by a qualified technician due to the high-voltage capacitor danger. Contact a certified appliance repair service.
