KitchenAid Range Error Code F01

Temperature sensor opened (open circuit in oven temperature sensor).

KitchenAid codesKitchenAid range codes

Temperature sensor opened (open circuit in oven temperature sensor).

First step from the service manual

1. Unplug range or disconnect power. 2. Check sensor connection. 3. Measure sensor resistance (1080 Ω at 70°F [21°C]. Add 2 Ω per 1°F). 4. If resistance is not valid, replace sensor. 5. If sensor resistance and connections are good, check for pinched sensor wires from the control to the sensor. 6. If sensor resistance and connections are good, then check for welded-closed relays on the control.

What F01 means on a KitchenAid range

The F01 error code on a KitchenAid range indicates an open circuit condition in the oven temperature sensor (also called an RTD, or resistance temperature detector). This sensor is a two-wire probe mounted inside the oven cavity that continuously reports oven temperature to the electronic control board. It does this by changing its electrical resistance in proportion to temperature. At 70°F (21°C), a properly functioning sensor reads 1080 ohms, with resistance increasing approximately 2 ohms for every 1°F rise in temperature. When the control board detects no signal or an out-of-range resistance reading, it interprets this as an open circuit and triggers the F01 fault.

The most common causes include a failed sensor element, a loose or corroded connector at either the sensor or the control board, and damaged wiring along the sensor harness. Pinched wires are a particular concern on ranges where the wiring runs through or near the rear panel, as installation or servicing can compress the insulation and eventually break the conductor inside. Less commonly, a relay on the control board itself can weld closed, creating a circuit condition that mimics a sensor fault even when the sensor and wiring test within spec.

Diagnosing F01 requires a multimeter to measure resistance at the sensor connector after disconnecting power. A reading near 1080 ohms at room temperature confirms the sensor is intact. If resistance is correct and connections are secure, the wiring harness should be inspected along its entire path for pinching or chafing before the control board is considered as the root cause.

Common causes of F01

  1. 01

    Failed oven temperature sensor

    Part replacement

    The sensor element itself has broken internally, creating an open circuit. Confirm by measuring resistance at the sensor connector: a reading far outside 1080 ohms at 70°F indicates a failed sensor that needs replacement.

  2. 02

    Loose or corroded sensor connector

    Wiring / connection

    The plug connecting the sensor wiring to the sensor probe or to the control board may have worked loose or developed corrosion. Inspect both ends of the sensor harness for loose terminals or oxidation and reseat the connectors firmly.

  3. 03

    Pinched or damaged sensor wiring

    Part replacement

    The wiring harness running from the control board to the sensor can become pinched against the oven frame or rear panel, eventually breaking the conductor inside the insulation. Trace the full length of the harness and look for compressed, kinked, or abraded sections.

  4. 04

    Welded relay on the control board

    Part replacement

    If the sensor resistance and all wiring check out correctly, a relay on the electronic control board may have welded itself closed, producing a fault signal even though the sensor is functional. This is diagnosed by exclusion after confirming sensor and wiring integrity.

Frequently asked questions about F01

What does F01 mean on a KitchenAid range?
F01 indicates that the electronic control board has detected an open circuit in the oven temperature sensor. The sensor is responsible for reporting oven temperature by varying its electrical resistance, and when the control receives no valid signal, it locks out oven operation and displays F01. The fault can originate at the sensor itself, its wiring, its connectors, or in rare cases the control board.
Can I fix the F01 error on my KitchenAid range myself?
Many F01 faults can be resolved by a knowledgeable DIYer. After unplugging the range, you can inspect and reseat the sensor connectors, check the wiring harness for visible damage, and use a multimeter to test sensor resistance against the 1080-ohm specification at room temperature. If the sensor is out of spec, replacing it is a straightforward repair. If the fault points to a control board relay, that repair is more complex and typically requires a professional.
Is it safe to use my KitchenAid range while F01 is displayed?
No, you should not use the oven while F01 is active. The error means the control board cannot monitor oven temperature, which removes the safety feedback loop that prevents overheating. Surface burners on a gas range may still operate, but the oven should remain off until the fault is diagnosed and repaired.
Will resetting the range clear the F01 error code?
Unplugging the range or cycling the breaker may temporarily clear the display, but if the underlying fault is still present, F01 will return as soon as the control attempts to use the oven sensor again. A reset is not a fix. The sensor circuit needs to be tested and the root cause corrected before the error will stay clear.
How much does it cost to repair a KitchenAid range F01 error?
If only the oven temperature sensor needs replacement, parts typically cost between $20 and $60, and the total repair including labor generally falls in the $100 to $200 range. If the control board is at fault, parts alone can range from $150 to $350 or more, with total repair costs potentially reaching $300 to $500 depending on the model and service rates in your area.
