What Does Error F4 Mean?

The Kenmore oven error code F4 signifies a fault in the lower oven’s temperature sensor system, which can lead to erratic temperature readings and inconsistent cooking. This may be due to a faulty sensor, open or shorted wiring, or out-of-range sensor readings. Common symptoms include the F4 error displayed on the control panel, the oven failing to heat, or cycling off during preheat attempts.

Common Symptoms:

  • Error code F4 displayed on control panel
  • Oven fails to heat or starts but displays error immediately
  • Cycles off when attempting to preheat

Possible Causes

  • Faulty lower oven temperature sensor (medium)
  • Wiring/connector issue for temperature sensor (medium)

How to Fix Error F4

DIY Fix Basic user checks

  1. Turn oven off and disconnect power (unplug or breaker off)
  2. Visually inspect oven interior temperature sensor for damage or loose wiring
  3. Attempt to clear error by resetting power and retry heating

Technician Only Diagnostic and replacement of temperature sensor

  1. Disconnect oven from power and access rear or interior cavity to reach the temperature sensor
  2. Use a multimeter to measure resistance of the temperature sensor at room temperature; compare to expected ~1090 ohms (varies by model)
  3. If resistance reading is out of range or open/shorted, remove and replace the faulty sensor with model‑specific part
  4. Check wiring harness and connections for continuity and secure fit
  5. Restore power and verify error cleared

Parts needed: Oven temperature sensor (lower), Multimeter

🛑 When to Call a Pro:
  • If resistance readings are normal yet error persists
  • If wiring damage is found beyond basic connector issues
  • If you are not confident working with internal oven electrical components
