Jenn-Air Oven / Range Error Codes

Jenn-Air Oven / Range Error Code F3

If you’ve encountered Error Code F3 on your Jenn-Air Oven/Range, it signals an anomaly involving the cooling fan. Specifically, the cooling fan is running despite no active oven functions being selected. This discrepancy may indicate an underlying issue with the oven temperature sensor or the wire harness connected to it.

Possible Causes:

  1. Faulty Oven Temperature Sensor: The oven temperature sensor plays a crucial role in regulating the temperature inside the oven. A malfunctioning sensor can send inaccurate signals, leading to the unnecessary activation of the cooling fan.
  2. Issues with the Wire Harness: A damaged or improperly connected wire harness to the oven temperature sensor can disrupt the communication between components. This disruption may trigger the cooling fan to operate without a corresponding oven function.

Troubleshooting Steps:

  1. Inspect the Oven Temperature Sensor:

    • Check for visible damage or signs of wear on the oven temperature sensor.
    • Test the sensor’s resistance with a multimeter to ensure it falls within the specified range.
  2. Examine the Wire Harness:

    • Inspect the wire harness for any loose connections or physical damage.
    • Ensure the wire harness is securely connected to both the oven temperature sensor and the main control board.
  3. Reset the Appliance:

    • Power off the oven and unplug it from the electrical outlet for a few minutes.
    • Reconnect the power and check if the error code persists.
  4. Professional Assistance:

    • If the issue persists after performing basic troubleshooting, it’s advisable to seek assistance from a qualified appliance repair technician. They have the expertise to diagnose and address more complex problems.

Error Code F3 is a clear indicator of a potential malfunction in the temperature regulation system of your Jenn-Air Oven/Range. By systematically examining the oven temperature sensor and its wire harness, you can take crucial steps towards resolving this issue. If in doubt or if the problem persists, enlisting the help of a professional technician ensures a thorough diagnosis and effective resolution.
