KitchenAid Oven F3 E0 Error: Upper Oven Sensor Open
What Does KitchenAid Oven Error Code F3 E0 Mean? Error code F3 E0 on a KitchenAid wall oven signals an open circuit on the upper oven temperature sensor (RTD probe). The sensor is a resistance-based device mounted on the back wall of the cavity; the control board continuously measures its resistance to calculate cavity temperature. […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Without a functioning temperature sensor the oven cannot prevent overheating. Do not operate the oven in any cooking mode until the sensor is replaced and the fault cleared.
Can I reset the code?
No. F3 E0 is a hardware fault — a breaker reset will not resolve it. The code returns the moment the control board samples the sensor circuit and finds it open. Replacement of the sensor or its harness is required.
When to stop immediately?
Stop if you notice: Oven produces burning smells without a visible set temperature on the display, F3 E0 appears on every cook attempt after sensor replacement, pointing to a board fault.
Symptoms You May Notice
Upper oven cavity fails to preheat and shuts off within seconds of starting
The bake or broil element energizes briefly, but without a valid temperature reading the control board immediately cuts power to all heating elements.
Display shows dashes or 0°F in place of the rising preheat temperature
Rather than climbing from room temperature toward the set point, the display either freezes at zero or shows dashes, confirming the sensor signal is absent.
Self-clean cycle will not initiate on a double-wall oven
On KODE double-wall models the upper-cavity self-clean is blocked because the control requires a valid sensor reading before engaging the door latch and high-heat cycle.
Possible Causes
Failed upper oven RTD temperature sensor
The resistance-based sensor probe inside the cavity has broken its internal wire, creating an open circuit that the board reads as infinite resistance.
DIY PossibleBroken or corroded sensor harness wire
The two-wire harness from the sensor probe to the control board has a break or corroded connector, interrupting the signal path.
DIY PossibleControl board sensor input circuit failure
Rarely, the board's own sensor measurement circuit has failed, causing it to read all sensors as open even when the probes are intact.
Requires ProfessionalSafe Checks You Can Do
-
1
Inspect the sensor probe and harness connector
With the oven fully de-energized and unplugged, locate the RTD probe on the back wall of the upper cavity. Check that its two-pin connector is fully seated and that the harness wires show no visible damage or corrosion.
Wiggle the connector gently — a loose fit here is a frequent cause of intermittent F3 E0 on KOSE and KODE models.

Test sensor resistance with a multimeter
Disconnect the sensor harness from the board side and measure resistance across the sensor's two terminals. A healthy KitchenAid oven RTD reads approximately 1,080–1,100 ohms at room temperature (68°F).
An open-loop (OL) or extremely high reading confirms the sensor has failed and must be replaced.
Tools required
When to Call a Professional
Contact a qualified technician if:
- New replacement sensor still reads open on the multimeter — board input has failed
- Harness damage extends into the oven body beyond reach of DIY repair
- Code appears alongside F9 E0 runaway-temperature codes
