What Does Error F4 Mean?

The Whirlpool Oven F4 error code indicates a malfunction in the temperature sensing circuit, typically caused by a shorted or defective oven temperature sensor (RTD). This can lead to incorrect temperature readings or the oven failing to heat properly. The error may appear at the start of a cooking cycle or immediately after powering on the oven, making it essential to address for safe and efficient operation.

Common Symptoms:

  • F4 displays on the control panel
  • Oven fails to heat or regulate temperature properly
  • Error appears at start of a cooking cycle or immediately after power up

Possible Causes

  • Oven temperature sensor (RTD) is shorted or defective (medium)

How to Fix Error F4

DIY Fix Basic power reset and visual inspection

  1. Turn off power to the oven at the circuit breaker or unplug it.
  2. Wait at least one minute before restoring power.
  3. Observe whether the F4 error returns when the oven is powered on.
  4. Visually inspect the oven temperature sensor area for obvious damage or loose wires (no disassembly beyond appliance panels).

Technician Only Test and replace faulty temperature sensor

  1. Disconnect power to the oven.
  2. Remove back panel to access the oven temperature sensor.
  3. Disconnect the sensor harness and test the sensor resistance with a multimeter.
  4. Replace sensor if resistance is out of expected range or if visual damage is present.
  5. Reassemble and test oven to confirm error resolution.

Parts needed: Oven temperature sensor (RTD), Multimeter for testing

Technician Only Inspect and repair wiring / control board

  1. Disconnect power to the oven.
  2. Inspect wiring between the temperature sensor and control PCB for damage or loose connectors.
  3. Repair or replace damaged wiring harnesses as needed.
  4. If wiring is intact and sensor tests normal, test or replace the oven control board per service manual.
  5. Reassemble and verify oven operation.

Parts needed: Wire harness, Control board (if needed)

🛑 When to Call a Pro:
  • If error persists after replacing sensor and checking wiring
  • If you are not comfortable working with live electricity or accessing internal components
  • If the control board is suspected and proper diagnostic tools are unavailable
