What FR means on a GE range

The FR error code on a GE double oven range indicates that the control system has detected a fault condition associated with the second oven cavity. This code is exclusive to double oven configurations, where the upper and lower oven sections operate with separate temperature sensing circuits. The error is triggered when the second oven's control electronics detect an abnormal signal from the temperature sensor or a failure within the secondary oven control board itself.

The temperature sensor, also called an oven sensor or RTD (resistance temperature detector), is a key component in this circuit. It provides resistance-based feedback to the control board, allowing the system to regulate oven temperature accurately. A properly functioning sensor will exhibit a predictable resistance value that changes with temperature. If the sensor is open, shorted, or producing an out-of-range resistance reading, the secondary oven board will flag the FR code. Wiring harness issues, including damaged insulation, loose connectors, or corroded terminals between the sensor and the board, can produce the same fault.

Diagnosis should begin with a physical inspection of the second oven sensor and its connecting harness. Check the sensor connector at the board for corrosion or looseness, and inspect the harness routing for any pinch points or heat damage. If the sensor and wiring check out, the secondary oven control board itself may have failed internally and will need replacement. Board failures can occur due to heat stress, power surges, or component aging.

Common causes of FR

  1. 01

    Faulty second oven temperature sensor

    Part replacement

    The RTD temperature sensor in the second oven cavity may be open or shorted, sending an invalid resistance signal to the control board. Inspect the sensor and measure its resistance to check for an out-of-range reading.

  2. 02

    Damaged or disconnected wiring harness

    Wiring / connection

    The harness connecting the second oven sensor to the control board may have a loose connector, broken wire, or heat-damaged insulation. Visually inspect the full harness run and check all connector terminals for corrosion or looseness.

  3. 03

    Corroded sensor connector

    Wiring / connection

    Moisture or heat cycling can cause corrosion at the sensor plug or board connector, increasing resistance in the circuit and triggering a fault. Cleaning or reseating the connector may resolve the issue.

  4. 04

    Failed secondary oven control board

    Part replacement

    If the sensor and harness test within acceptable parameters, the secondary oven control board may have an internal failure. Board faults can result from heat stress or power surges and typically require board replacement.

Frequently asked questions about FR

What does FR mean on a GE range?
The FR code on a GE range indicates a second oven error and only appears on double oven models. It means the control system has detected a problem with the temperature sensing circuit or control board for the second oven cavity. The first steps are to check the oven sensor and its wiring harness, and then replace the secondary oven board if needed.
Can I fix the FR error on my GE double oven range myself?
Some causes of the FR code are DIY-friendly, such as reseating a loose sensor connector or inspecting the wiring harness for visible damage. If the temperature sensor has failed, replacing it is a moderately straightforward repair for someone comfortable working with appliances. If the secondary oven control board has failed, that repair is more involved and may be better handled by a technician.
Is it safe to keep using my GE range when the FR code is showing?
The primary oven on your double oven range may still function, but the second oven should not be relied upon while the FR code is active. Using an oven with a faulty temperature sensor risks unregulated heating, which could result in undercooked food or overheating. It is best to stop using the second oven until the fault is diagnosed and resolved.
Will resetting my GE range clear the FR error code?
Resetting the range by disconnecting power for a few minutes may temporarily clear the FR code, but it will return if the underlying fault is still present. A reset is useful for confirming whether the error is intermittent or persistent, but it does not fix a faulty sensor, damaged harness, or failed control board. Proper diagnosis and repair of the root cause is required for a permanent fix.
How much does it cost to repair a GE range showing the FR error code?
Repair costs depend on the root cause. A replacement oven temperature sensor typically costs in the range of $20 to $60 for the part, while a secondary oven control board can range from $80 to $200 or more depending on the model. If you hire a technician, expect to add a service call fee and labor costs on top of the part price.
