What FR means on a Maytag range

The FR error code on a Maytag double oven range indicates that the control system has detected a fault condition in the second oven cavity. This code is exclusive to double oven configurations, where the upper and lower oven compartments each have their own temperature sensor and, in many cases, separate control boards. When the second oven's control circuitry receives an abnormal signal from its temperature sensor or loses communication with the sensor entirely, it triggers the FR code to alert the user and technician that the secondary baking or broiling function is compromised.

The temperature sensor in the second oven is a resistive probe, typically a negative temperature coefficient (NTC) type, that changes resistance predictably as oven temperature rises and falls. The control board monitors this resistance to determine cavity temperature. If the sensor reads out of expected range, shorts to ground, or the wiring harness between the sensor and board develops an open circuit or damaged connector, the board interprets this as an error and displays FR. Physical damage to the harness from heat exposure, pinched wires behind the oven liner, or a corroded connector at either the sensor or board end are frequent causes.

Diagnosis begins with inspecting the second oven temperature sensor and its associated wiring harness. The sensor's resistance should be checked at room temperature and compared against the expected specification for that model. If the sensor and harness both check out within spec and connections are secure, the fault points to the second oven control board itself, which will need to be replaced to restore normal operation.

Common causes of FR

  1. 01

    Faulty second oven temperature sensor

    Part replacement

    The temperature sensor probe in the second oven cavity may have failed, drifted out of specification, or shorted internally. Checking resistance with a multimeter at room temperature and comparing it to the expected value will confirm whether the sensor is defective.

  2. 02

    Damaged or disconnected wiring harness

    Wiring / connection

    The harness connecting the second oven sensor to the control board may have a broken wire, burnt insulation, or a loose connector, particularly near areas exposed to heat. A visual inspection and continuity test of the harness will identify any open or short circuits.

  3. 03

    Corroded or loose connector pins

    Wiring / connection

    Connector terminals at the sensor plug or at the board can corrode or back out over time, causing intermittent or total loss of signal. Carefully reseating and inspecting connectors for corrosion or bent pins can resolve this without replacing major components.

  4. 04

    Defective second oven control board

    Part replacement

    If the sensor and harness both test within normal parameters, the second oven control board itself may have failed internally. This board processes the sensor signal and manages oven functions, and a failure here requires board replacement.

Frequently asked questions about FR

What does FR mean on a Maytag range?
The FR code on a Maytag range indicates that the control system has detected an error in the second oven, and it only appears on double oven models. It typically points to a problem with the second oven temperature sensor, its wiring harness, or the second oven control board. The affected oven cavity should not be used until the fault is diagnosed and corrected.
Can I fix the FR error code myself?
A knowledgeable DIYer can perform initial diagnostics such as inspecting the wiring harness for visible damage, checking connector pins, and testing the temperature sensor resistance with a multimeter. If the sensor is faulty, replacing it is a straightforward repair on most double oven ranges. However, if the second oven control board needs replacement, some experience with appliance electronics is recommended to ensure safe and correct installation.
Is it safe to keep using the range when the FR code is displayed?
The FR code specifically affects the second oven cavity, so the primary oven or cooktop surface may still function normally. However, the second oven should not be used while this fault is active, since the control system cannot properly monitor its temperature. Continuing to use a faulty oven cavity could result in overheating or uncontrolled baking conditions.
Will resetting the 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 ruling out a one-time electronic glitch, but persistent FR codes require hands-on diagnosis of the sensor, harness, and control board. Do not rely on repeated resets as a long-term solution.
How much does it cost to repair the FR error code on a Maytag double oven range?
Repair costs vary depending on whether the fix involves the temperature sensor, the wiring harness, or the second oven control board. A replacement temperature sensor typically runs in the range of $20 to $60 for the part alone, while a second oven control board can cost anywhere from $100 to $300 or more depending on the model. Adding professional labor will increase the total, generally bringing a full repair into the $150 to $450 range depending on parts needed and local service rates.
