What Does Error F3 Mean?
The Kenmore oven F3 error indicates a malfunction in the temperature sensor or its circuit, leading to erratic temperature readings and inconsistent cooking performance. This error often appears during preheating or baking and may cause the oven to stop heating altogether. In some cases, it can also be triggered by a stuck keypad. To resolve the issue, inspecting the temperature sensor and its wiring is recommended.
Common Symptoms:
- Oven stops heating when F3 is displayed
- F3 appears during preheat or bake cycles
- Temperature reading failure or abnormal sensor readings
Possible Causes
- Faulty oven temperature sensor (open circuit or incorrect resistance) (medium)
- Loose or damaged wiring/connector to temperature sensor (medium)
- Stuck key or keypad input issue (less typical) (low)
How to Fix Error F3
DIY Fix Basic inspection and power reset
- Turn off power to the oven at the breaker or unplug it.
- Wait 5–10 minutes to allow any control reset.
- Restore power and observe if the F3 code returns.
Technician Only Test and replace temperature sensor and inspect wiring
- Disconnect power and access the oven’s temperature sensor (usually at rear wall inside the cavity).
- Use a multimeter to measure resistance; typical room‑temp value is ~1000–1100 Ω (model dependent).
- Replace the sensor if out of range or open circuit.
- Inspect and repair/replace any damaged wiring harness or connectors between the sensor and control board.
Parts needed: Oven temperature sensor (RTD), Wiring harness/connectors
Technician Only Control board/keypad diagnosis and replacement
- If sensor and wiring check out, test control board inputs and keypad for stuck key or input faults.
- Replace control board or keypad assembly if confirmed faulty.
Parts needed: Electronic oven control board, Keypad/display assembly
- If you are unsure how to safely diagnose electrical components or use a multimeter
- If replacing the sensor does not clear the F3 code
- If control board or keypad replacement is required
