GE Range Error Code F6 E3

F6 E3 means the mini oven or warming drawer has detected an over-temperature condition, meaning the compartment has exceeded its safe upper heat limit. The control board monitors the warming drawer temperature through a dedicated sensor and shuts down the circuit when the temperature goes too high. This code typically points to a faulty temperature sensor, a stuck relay, or a problem with the control board.

The warming drawer or mini oven function should not be used while F6 E3 is active, as the over-temperature fault indicates the heating circuit is not being properly controlled. The main oven may still be operable, but continued use of the warming drawer before repairs are made could pose a fire or damage risk. Address the fault before relying on that compartment again.

Repair costs vary depending on the root cause. Replacing a warming drawer temperature sensor typically falls in the range of $20 to $80 for the part, while a control board replacement can run anywhere from $100 to $350 or more for the part alone. Adding professional labor costs will increase the total, generally ranging from $150 to $500 depending on the repair needed and your location.

Some steps, like checking for blocked airflow or reseating the warming drawer, can be done without special tools. However, testing the temperature sensor resistance, cycling the relay in Diagnostics mode, and replacing control board components generally require a multimeter and comfort working with electrical components. If you are not experienced with appliance diagnostics, a qualified technician is recommended.

Disconnecting power to the range for a few minutes may temporarily clear the error code, but if the underlying problem with the sensor, relay, or control board is not repaired, the fault will return as soon as the warming drawer is used again. A power reset alone is not a fix, only a temporary measure for diagnostic purposes.
