KitchenAid F3E0 Oven Temperature Sensor Open (RTD)
KitchenAid oven F3E0 means the oven temperature sensor (RTD) reads open or out of range. Usually a failed sensor or broken sensor wiring.
KitchenAid oven code F3E0 means the oven temperature sensor (RTD) is reading open or out of range: the control sees an impossibly high resistance and cannot measure oven temperature. The fix is almost always replacing the temperature sensor or repairing its wiring.
What F3E0 means
F3E0 is an oven temperature sensor fault on the Whirlpool platform. The control monitors the resistance of the RTD sensor, which should read about 1080 to 1100 ohms at room temperature. When the control reads an open circuit (infinite resistance) it posts F3E0 and cannot safely regulate the bake or broil temperature.
Severity:Service recommended · Appliance:Wall Oven
Why F3E0 happens
The RTD sensor probe fails internally and goes open, especially after years of high-heat and self-clean cycles. The wiring or connector from the sensor to the control can burn, corrode, or come loose at the back of the oven. Less often the control board's sensor-input circuit fails.
Common causes
- Failed oven temperature sensor (RTD) reading open
- Broken, burned, or disconnected sensor wiring
- Corroded sensor connector at the rear of the oven
- Control board sensor-input circuit fault
- Damage from a prior self-clean cycle
What you'll typically see
- F3E0 displayed when Bake or Broil is selected
- Oven will not heat or shuts off the heat
- Temperature readings that are wildly off
- Code may appear during preheat
- Long preheat times before the fault posts
Parts involved in F3E0
- Oven temperature sensor (RTD) — Primary fix; replaced when it tests open or far from ~1080 ohms at room temperature
- Sensor wiring harness / connector — Repaired or replaced when burned, corroded, or loose at the sensor plug
- Control board (ERC) — Replaced if a good sensor still reads open, indicating an input-circuit fault
What you can check yourself
- Power-cycle the oven at the breaker for two minutes
- Confirm the code appears only when heating is requested
- Note any burning smell or discoloration at the back wall
- Do not attempt to access the sensor probe inside the cavity
When to book a pro
Measuring the RTD resistance and tracing its harness requires disconnecting power and accessing the rear of the oven. A technician confirms whether the sensor, wiring, or board input is open before replacing parts.

F3E0 FAQ
What does F3E0 mean on a KitchenAid oven?
The oven temperature sensor (RTD) is reading open or out of range, so the control cannot measure oven temperature. It is usually a failed sensor or broken sensor wiring.
Can I replace the oven sensor myself?
The sensor is technically accessible, but it sits in a high-heat cavity with a harness that must be tested and routed correctly. We recommend a technician verify the open circuit first so you do not replace a good sensor.
What should the oven sensor read?
A healthy RTD reads roughly 1080 to 1100 ohms at room temperature. An open reading (infinite resistance) confirms the F3E0 fault.
Is it safe to use the oven with F3E0?
The control disables heat because it cannot regulate temperature, so there is no overheating risk, but the oven will not cook until it is fixed.
What is the difference between F3E0 and F3E1?
F3E0 is the sensor reading open (too high resistance); F3E1 is the sensor reading shorted (too low resistance). Both involve the same RTD sensor and wiring.
How much does an F3E0 repair cost?
Our diagnostic visit is a flat $89, applied toward the repair, and the sensor replacement carries a 365-day warranty. Call (650) 668-1554 to schedule.
