GE Oven Error Code F6

The F6 code on a GE microwave oven means the control board detected an excessively high temperature inside the cooking cavity. The oven shuts down automatically to protect itself and prevent a safety hazard. The fault involves the cavity thermistor, the fan motors responsible for cooling, and the wiring connecting these components to the control board.

Yes, the F6 code is a protective fault triggered by high cavity temperature, so the oven should not be operated again until the cause is identified and corrected. Continuing to use the oven while the underlying issue persists could result in further component damage or a fire risk. Allow the unit to cool completely before any inspection.

Repair costs vary depending on the faulty component. A replacement cavity thermistor is typically an inexpensive part, with the total repair cost including labor ranging from around $75 to $175. A failed fan motor assembly can run between $100 and $250 installed. Control board replacement is the most expensive scenario, often ranging from $200 to $400 or more depending on the specific model and labor rates in your area.

Some causes of the F6 error are DIY-accessible, such as cleaning blocked vents, reseating loose wiring connectors, or confirming that fan blades are not obstructed. However, testing a thermistor with a multimeter and replacing internal components like fan motors or the control board requires comfort working with appliance electronics and, importantly, discharging the high-voltage capacitor before opening the unit. If you are not experienced with appliance repair, a qualified technician should handle internal component diagnosis.

Unplugging the oven for a few minutes and restoring power may temporarily clear the F6 code if the unit had simply overheated during a long cooking cycle and the temperature has since returned to normal. However, if the code returns during normal cooking, there is an underlying component issue with the thermistor, fan motors, or wiring that requires proper diagnosis and repair. Resetting alone does not fix a hardware fault.
