GE Oven Error Code F6-E0

F6-E0 means the microwave cavity temperature exceeded safe operating limits during a cooking cycle. The oven's control system detected this over-temperature condition through the microwave cavity temperature sensor and shut down to prevent damage. The fault can be caused by a failing sensor, a wiring connection problem, or an actual overheating event in the cavity.

You should not continue using the microwave function while this error is active. The code indicates either a real over-temperature condition or a sensor failure that prevents the control board from accurately monitoring cavity heat. Using the microwave without resolving the fault could lead to further component damage or a genuine overheating hazard.

If the fix involves only reseating a wiring connection, there may be little to no parts cost. Replacing a microwave cavity temperature sensor typically costs in the range of $20 to $75 for the part, depending on the model. If a technician is needed, expect to add $100 to $200 or more in labor costs depending on your location and the extent of diagnosis required.

Some steps are DIY-friendly, such as inspecting the sensor wiring harness for loose or corroded connections and checking the cavity vents for blockages. Measuring the temperature sensor's resistance with a multimeter is also manageable for a confident DIYer. However, if the sensor or control board needs replacement, comfort with appliance disassembly and basic electrical work is required, and some may prefer to call a technician.

A reset by cutting power to the unit for a few minutes may temporarily clear the error code, but if the underlying problem such as a faulty sensor or wiring fault is still present, the code will return during the next cooking cycle. A reset is useful for confirming whether the fault is intermittent, but it is not a repair.
