KitchenAid Range F3 E0 Error: Oven Sensor Open Circuit
What Does KitchenAid Range Error Code F3 E0 Mean? F3 E0 on a KitchenAid range means the control board is reading an open circuit from the oven temperature sensor — the RTD probe mounted inside the cavity. An open circuit means resistance is effectively infinite, which tells the board it has no temperature data. Without […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Without a working temperature sensor the control cannot regulate oven heat. The oven will not function while F3 E0 is active, making it safe from a fire standpoint, but it cannot be used for cooking.
Can I reset the code?
No. F3 E0 is caused by a hardware open circuit — resetting the control board will not restore the missing sensor signal. The fault will return immediately after every reset until the sensor or harness is repaired.
When to stop immediately?
Stop if you notice: Oven does not heat at all after a breaker reset, Sensor resistance reads open or out of range with a multimeter.
Symptoms You May Notice
Oven fails to reach the set temperature and shuts off
The cavity never warms to the target temperature — elements energize briefly then cut out, and the display shows F3 E0 within the first few minutes of preheat.
Control shows an unusually low or dashed temperature reading
Instead of a climbing temperature value during preheat, the display shows dashes or a static near-ambient reading, indicating no valid sensor signal is reaching the board.
Bake and broil both fail; surface burners work normally
Because the F3 E0 fault affects only the oven-temperature circuit, the gas surface burners or electric surface elements on the range continue to function as expected.
Possible Causes
Failed oven temperature sensor (RTD probe)
The resistance-temperature detector mounted on the oven cavity wall has an open internal element, sending infinite resistance to the control board.
DIY PossibleBroken or disconnected sensor wire harness
The two-wire harness connecting the sensor to the control board has broken, corroded, or pulled free from its connector, interrupting the circuit.
DIY PossibleDamaged control board sensor input circuit
If the sensor and harness test correctly, the fault lies in the board's sensor-reading circuitry — a component-level failure that requires board replacement.
Requires ProfessionalSafe Checks You Can Do
-
1
Check sensor resistance with a multimeter
With the range unplugged, locate the sensor probe on the upper-rear oven cavity wall, disconnect its two-wire harness, and measure resistance across the sensor terminals. A good sensor reads approximately 1,080–1,090 ohms at room temperature (68°F).
An open-circuit reading (OL or infinite resistance) confirms the sensor has failed and needs replacement — it is typically a from $20 part available for all KitchenAid range models.

Inspect the sensor wire harness for damage
Trace the two-wire harness from the sensor to the control board connector. Look for burned insulation, broken wires, or a connector that has pulled free from its lock tab.
A broken wire near the connector is a common failure point on slide-in models where the harness flexes when the oven door opens repeatedly.
When to Call a Professional
Contact a qualified technician if:
- Sensor resistance is within spec but the code persists — suggests a faulty control board
- Harness damage is located inside the oven cavity wall, requiring panel removal
- Model is under warranty and the sensor is an in-warranty failure
