Whirlpool Oven / Range / Wall Oven Error Code F3 – Temperature Sensor Fault

What Does This Error Code Mean?

The Whirlpool oven error code F3 typically indicates a temperature sensor (RTD sensor) problem or an issue with temperature detection inside the oven. In simple terms, your oven is having trouble accurately reading the internal temperature. The sensor is responsible for telling the control system how hot the oven is. When this signal is missing, incorrect, or unstable, the oven cannot properly regulate heat. As a result, the oven may not heat correctly, may overheat, or may stop functioning as a protective measure. This is a common Whirlpool oven troubleshooting error linked directly to temperature monitoring failure.

Causes of the Error

The F3 error code is commonly caused by:

Safe Troubleshooting Steps

Before contacting a technician, you can safely perform these checks


  • Check Power Stability: Confirm the oven is receiving stable electrical supply
  • Inspect Ventilation: Ensure oven vents are not blocked, allowing proper airflow
  • Check Display Behavior: Note whether the error appears immediately or after heating begins
  • Allow Oven to Cool: If recently used, let it fully cool before testing again
  • Power Reset: Turn off the oven at the breaker for 5–10 minutes, then restart

  • The F3 error is considered high severity because it directly affects temperature measurement. Without accurate sensor readings, the oven cannot regulate heat properly, which can lead to unsafe cooking conditions or complete shutdown of heating functions.
