Code still on the display
If the message is still there after the reset, schedule a technician to examine the oven.
Our Maytag wall oven repair visits cover San Francisco and the surrounding Bay Area. Phone (415) 649-2156 with the F1 E4 code, the oven model number and what the reset did.
Model compatibility: Maytag reuses codes across series and model years, so F1 E4 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 microwave appliance manager, the microwave power relay or the wiring may have a problem.
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.
