9 error codes

CodeMeaning
F3F3 means the control board detected a continuous closed circuit on the touchpad for more than 60 seconds straight. A button is stuck or the internal membrane layers fused together and the board thinks someone's been holding a key forever. It shuts everything down rather than risk an unintended start.
highintermediate
F3The F3 error code on a GE microwave indicates a shorted touch pad or keypad circuit. This occurs when the control board detects that a button has been pressed or shorted for more than 60 consecutive seconds.

HUBGE microwave ovens display error codes including PF (power failure), Sensor Error, Food Error, and various F-codes. GE uses a simpler code system than Whirlpool - most errors are descriptive text rather than alphanumeric codes.

NOT-HEATINGThe magnetron is the vacuum tube responsible for generating microwaves. A failure means the component has either lost its vacuum, the internal filament has broken, or the ceramic magnets have cracked, resulting in no heat production.
highadvanced
PFPF on a GE microwave simply means Power Failure - the power was interrupted and the microwave needs its clock reset. This is NOT an error code indicating a fault. PF is the most commonly searched GE microwave 'error' despite being a normal informational message.
lowbeginner
SENSOR-ERRORSensor Error on a GE microwave means the built-in humidity sensor detected abnormal moisture readings during a sensor cooking cycle. The sensor measures steam output from the food to determine when cooking is complete, and the error triggers when readings are outside expected parameters.

TROUBLESHOOTINGGeneral diagnostic guide for GE Spacemaker over-the-range microwaves. When one of these units acts up, it's usually something in the safety circuit or the high-voltage section. The machine's designed to shut itself down if it doesn't see the right signals, which can make it look way more broken than it actually is.
