Whirlpool Microwave Error Codes

All Whirlpool microwave error codes with step-by-step troubleshooting, multimeter specs, and OEM part numbers.

8 error codes

CodeMeaning
DOOR-ERRORThe 'Open/Close Door' or 'Door' error on Whirlpool microwaves means the door interlock switches are not registering the door as properly closed. Microwaves have 3 door interlock switches as a safety system - all 3 must confirm the door is closed before the magnetron will energize.

F1 E4F1 E4 means the control board caught the power relay stuck closed when it should've opened. Basically the switch that turns the magnetron on and off can't turn off anymore. That's a safety shutdown, and it's serious. Don't try to bypass it.

F1 E6The relay is basically the on/off switch for the magnetron, the thing that actually generates the microwaves. F1E6 means the control board is sending the 'fire' signal to that relay but nothing's happening. The relay's either physically failed open, or the board's driver circuit that energizes the relay coil is shot and can't complete the switch.

F2 E1F2E1 on a Whirlpool microwave means the control board detected a touchpad key being pressed when no key should be active. This is a keypad membrane short circuit, typically from steam moisture penetrating the membrane layers.
moderatebeginner
F6The F6 code means the main control board detected a relay fault or internal logic failure. The processor tried to check the state of its own switching relays and got back garbage. Could be a welded relay, could be a fried microprocessor. Either way, the board's not doing its job and it knows it.

HUBWhirlpool over-the-range and countertop microwaves use F/E combination error codes. F1E4 means the main power relay is physically stuck on. F1E5 is a humidity sensor fault. F1E6 means the magnetron relay failed. F2E1 is a shorted keypad. F6 is a communication dropout between the main board and secondary board.

NO-HEATThe magnetron generates the microwave energy that heats your food. When it dies, the microwave looks completely normal from the outside, lights on, turntable spinning, timer counting down, but there's zero energy actually going into that food.
criticaladvanced
NOT-HEATINGThe microwave's getting power, the timer's counting down, but the magnetron, which is the component that actually generates the radio waves that heat your food, has failed or isn't receiving the high-voltage power it needs to fire up.
