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 E4F1E4 on a Whirlpool microwave indicates the control board detected that the microwave power relay is stuck in the closed (energized) position. This is a critical safety shutdown - if the relay is stuck closed, the magnetron could run uncontrolled.

F1 E6F1E6 on a Whirlpool microwave indicates the magnetron relay circuit has failed. The magnetron is the component that generates microwaves, and the relay controls power to it. F1E6 means the relay is either stuck or not responding to control board commands.

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.
