GE Range Error Code F3 E7

F3 E7 on a GE range means the control board has detected a short circuit in the warming drawer temperature sensor circuit. The sensor, also called a thermistor, is reading a resistance value outside the expected range, which indicates a shorted condition. This prevents the control system from accurately monitoring the warming drawer's temperature.

The F3 E7 code specifically affects the warming drawer circuit, so the main oven and cooktop burners may continue to operate. However, the warming drawer should not be relied on while this fault is active since its temperature is not being properly monitored. Addressing the fault promptly is recommended to avoid any unintended behavior from the control board.

If only the warming drawer sensor needs replacement, parts typically cost in the range of $20 to $60 depending on the model. If a technician is needed for diagnosis and installation, total repair costs including labor generally fall in the range of $100 to $250. A main control board replacement, if required, can push costs higher, often in the range of $200 to $400 or more with labor.

Yes, some causes of F3 E7 are DIY-friendly. Start by unplugging the range, removing the back panel, and checking that the warming drawer sensor connector is properly seated. If the connector looks fine, a technician or experienced DIYer can use a multimeter to test the sensor's resistance and determine whether the sensor or wiring needs to be replaced.

Resetting the range by unplugging it or cycling the breaker may temporarily clear the error display, but the code will return if the underlying problem with the warming drawer sensor or its wiring has not been corrected. A reset alone does not fix the shorted sensor condition.
