What F-37 means on a Maytag oven

The F-37 error code on a Maytag induction range indicates a Type 1 failure in the induction cooktop temperature sensor circuit. This sensor monitors the temperature of the induction cooking surface and communicates readings to the control board. When the control board detects that the sensor signal is outside the expected parameters, it triggers the F-37 fault and may disable the cooktop to prevent overheating or unsafe operation.

The induction cooktop temperature sensor is a negative temperature coefficient (NTC) thermistor, meaning its electrical resistance decreases as temperature rises. At room temperature, a properly functioning sensor should read between 184 kilohms and 292 kilohms. A reading outside this range indicates the sensor has failed internally, while a reading of zero ohms or open circuit (infinite resistance) points to a wiring or connection fault rather than sensor degradation.

The most common causes of this fault are a failed thermistor, a loose or corroded connector at the sensor or control board, and damaged wiring in the sensor harness. Physical damage to the cooktop surface near the sensor location can also affect sensor performance. Because the cooktop may be disabled while this fault is active, diagnosis should begin with a resistance check of the sensor after disconnecting power, followed by an inspection of all connectors and wire routing in the sensor circuit.

Common causes of F-37

  1. 01

    Failed temperature sensor

    Part replacement

    The thermistor itself has degraded or failed, producing a resistance value outside the 184 kilohm to 292 kilohm range at room temperature. Confirm this with a multimeter reading directly at the sensor terminals after disconnecting power.

  2. 02

    Loose or disconnected sensor connector

    Wiring / connection

    The sensor plug may have worked loose from the control board or the sensor body, causing an intermittent or open circuit. Unplugging and firmly reseating all connectors in the sensor circuit often resolves this.

  3. 03

    Damaged sensor wiring harness

    Part replacement

    Wires in the sensor harness can become pinched, frayed, or burned from heat exposure near the cooktop, causing a short or open circuit. Visually inspect the full length of the harness for any visible damage.

  4. 04

    Corroded connector terminals

    Wiring / connection

    Moisture or food spillage can cause corrosion on the sensor connector pins, increasing resistance in the circuit enough to trigger a fault. Inspect the connector terminals for green or white oxidation and clean or replace as needed.

  5. 05

    Faulty control board

    Part replacement

    If the sensor measures within spec and all wiring and connectors check out, the control board may be misreading the sensor signal. This is the least common cause and should only be considered after all other components are confirmed good.

Frequently asked questions about F-37

What does F-37 mean on a Maytag oven?
F-37 on a Maytag oven indicates a Type 1 failure in the induction cooktop temperature sensor. The control board is detecting that the sensor signal is not within the expected range, which may disable the induction cooktop. The sensor should read between 184 kilohms and 292 kilohms at room temperature when measured with a multimeter.
Can I fix the F-37 error code myself?
A knowledgeable DIYer can diagnose this fault by disconnecting power and using a multimeter to check the sensor resistance. If the connector is simply loose, reseating it may clear the error. Replacing the thermistor is also a straightforward repair, though working on induction appliances requires care and the power must be fully disconnected before any work begins.
Is it safe to use my Maytag oven while the F-37 code is showing?
The induction cooktop may be disabled or unreliable while the F-37 fault is active, since the control board cannot accurately monitor surface temperature. It is best to avoid using the induction cooking zones until the sensor issue is resolved. The oven cavity itself may still function depending on the model.
Will resetting the oven clear the F-37 error code?
Unplugging the range or cutting power at the breaker for a few minutes will reset the control board and may temporarily clear the F-37 code. However, if the underlying sensor or wiring problem is not repaired, the fault will return once the appliance is powered back on and the cooktop is used.
How much does it cost to fix a Maytag F-37 error code?
If the fix is simply reseating a loose connector, there is no parts cost involved. A replacement induction cooktop temperature sensor typically costs between $20 and $80 depending on the specific model. If a control board replacement is needed, parts and labor costs can range from $150 to $400 or more.
