What F3 E6 means on a GE range

The F3 E6 error code on a GE range indicates that the control board has detected an open circuit in the warming drawer temperature sensor. The warming drawer uses a resistance temperature detector (RTD) or thermistor to monitor drawer temperature and relay that information back to the main control board. When the circuit is open, meaning electrical continuity is broken, the board cannot read any temperature signal from the sensor and triggers this fault code to protect the warming drawer from uncontrolled or unmonitored heating.

An open sensor circuit can result from a disconnected wiring harness connector, a broken wire in the sensor lead, or a failed sensor element itself. The sensor element can fail internally, breaking the circuit even when the connector and wiring appear intact. Because the warming drawer operates at relatively low temperatures compared to the oven cavity, sensor failures in this zone are sometimes caused by physical damage during installation or servicing rather than thermal stress.

Diagnosing this code begins with removing power from the range and accessing the rear panels to visually inspect the warming drawer sensor connector. If the connector is fully seated and wiring shows no visible damage, the next step is to measure the sensor resistance with a multimeter. An open reading, meaning no continuity or infinite resistance, confirms a failed sensor that requires replacement. A normal resistance reading with the connector verified good points toward a wiring harness fault or a control board issue.

Common causes of F3 E6

  1. 01

    Disconnected sensor connector

    Wiring / connection

    The wiring harness connector at the warming drawer sensor may have come loose or was never fully seated. This is the first thing to check after removing power and opening the rear access panel.

  2. 02

    Failed warming drawer sensor

    Part replacement

    The sensor element itself may have failed internally, creating an open circuit even when wiring and connectors look fine. A multimeter check showing infinite resistance across the sensor terminals confirms this failure.

  3. 03

    Damaged sensor wiring

    Part replacement

    A wire in the sensor lead may be broken or pinched, interrupting the circuit between the sensor and the control board. Inspect the full length of the wiring harness for cuts, abrasion, or sharp bends.

  4. 04

    Corroded or damaged connector pins

    Wiring / connection

    The connector terminals at the sensor or control board end may be corroded or bent, preventing a reliable electrical connection. Inspect the pins closely and clean or re-pin as needed.

  5. 05

    Faulty control board

    Part replacement

    If the sensor tests with correct resistance and all wiring and connectors are intact, the main control board may be misreading or failing to detect the sensor signal. This is the least likely cause and should be considered only after other components are confirmed good.

Frequently asked questions about F3 E6

What does F3 E6 mean on a GE range?
F3 E6 on a GE range means the control board is detecting an open circuit in the warming drawer temperature sensor. This indicates the sensor or its wiring has lost electrical continuity, so the board cannot monitor the warming drawer temperature. The fault is a protective measure to prevent the warming drawer from operating without temperature feedback.
Can I fix the F3 E6 error myself?
Yes, in many cases this repair is DIY-friendly. Start by unplugging the range, removing the rear access panel, and checking that the warming drawer sensor connector is firmly plugged in. If reconnecting the connector resolves the issue, no parts are needed. If the sensor itself has failed, replacing it requires purchasing the correct sensor for your model and basic electrical connector skills.
Will resetting the range clear the F3 E6 error?
Unplugging the range or cycling the breaker may temporarily clear the error code, but it will return as soon as the control board checks the sensor circuit again. The underlying open circuit in the warming drawer sensor must be repaired for the code to clear permanently.
Is it safe to use my range while it shows F3 E6?
The oven and surface burners may continue to function while this code is active, but the warming drawer should not be used. Without a functioning temperature sensor, the warming drawer has no reliable temperature control or safety monitoring. Avoid using the warming drawer until the sensor fault is repaired.
How much does it cost to repair the F3 E6 error on a GE range?
If the fix is simply reseating a loose connector, there is no parts cost. A replacement warming drawer sensor typically costs between $20 and $60 depending on the model. If a professional technician is needed, expect to pay between $100 and $250 total including the service call, labor, and parts.
