What F6 E3 means on a GE range

The F6 E3 error code on a GE range indicates that the mini oven or warming drawer has exceeded its safe upper temperature threshold. The control board monitors the warming drawer's temperature through a dedicated sensor, and when the measured temperature rises beyond the programmed limit, the board triggers this fault code and typically disables the warming drawer circuit to prevent damage or a safety hazard. This is an over-temperature condition, meaning the component is running hotter than it should under normal operation.

The warming drawer relies on a heating element, a temperature sensor, and a relay on the control board to regulate heat output. If any of these components fail or behave erratically, the drawer can overheat. A faulty temperature sensor that reads lower than the actual temperature will cause the control board to keep the heating element energized too long, producing excess heat. Similarly, a relay that sticks in the closed position will keep the element on continuously regardless of what the sensor reports.

Diagnosing this fault begins in the range's Diagnostics mode by pressing the Warming Drawer ON key followed by the Warming Drawer OFF key to manually cycle the relay. This test helps determine whether the relay is responding correctly to control board commands. If the relay fails to cycle, the control board or its relay circuit is likely the cause. If the relay cycles normally but the fault returns during operation, attention should shift to the temperature sensor and the heating element itself.

Common causes of F6 E3

  1. 01

    Faulty warming drawer temperature sensor

    Part replacement

    A defective temperature sensor can report inaccurate low readings, causing the control board to leave the heating element on too long. Inspect the sensor for damage and test its resistance to verify it is within the expected range.

  2. 02

    Stuck or failed relay on the control board

    Part replacement

    A relay that is stuck in the closed position will keep the warming drawer heating element energized continuously, causing the temperature to climb unchecked. Cycling the relay in Diagnostics mode (Warming Drawer ON then OFF) can help confirm whether the relay is responding to commands.

  3. 03

    Defective main control board

    Part replacement

    If the control board is not properly reading sensor data or cannot send the correct signals to shut off the warming drawer element, an over-temperature condition will result. This is often suspected after the sensor and relay have been ruled out.

  4. 04

    Warming drawer heating element shorted or malfunctioning

    Part replacement

    A heating element that has partially shorted can draw more current than intended and generate excessive heat even when the control board is attempting to regulate output. Inspect the element for visible damage and test for proper resistance.

  5. 05

    Blocked airflow or ventilation around the warming drawer

    Wiring / connection

    If the warming drawer cavity is obstructed by debris or the drawer is improperly seated, heat can build up faster than the sensor and control circuit can compensate. Check that the drawer slides fully into position and that there is no debris blocking vents.

Frequently asked questions about F6 E3

What does F6 E3 mean on a GE range?
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.
Can I fix the F6 E3 error myself?
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.
Is it safe to keep using my GE range if F6 E3 is showing?
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.
Will resetting the range clear the F6 E3 code?
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.
How much does it cost to repair an F6 E3 error on a GE range?
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.
