Jenn-Air Oven / Range Error Code FR

You’ve encountered Error Code FR on your Jenn-Air Oven/Range, and it’s signaling an issue with the second oven. Fret not, as we guide you through the intricacies of this error code for a seamless resolution.

Error Description: Second Oven Error Sensed

Possible Causes:

  1. Oven Temperature Sensor and Harness: Start by inspecting the oven temperature sensor and its harness. Over time, these components may wear out or become faulty, leading to irregularities in temperature readings. Ensure there are no loose connections or damaged wires.
  2. Second Board Malfunction: The second board, a crucial component in the oven’s electronic system, might be at the heart of the problem. Consider replacing the second board if the issue persists after examining the temperature sensor and harness.

Troubleshooting Steps:

  1. Inspect the Temperature Sensor:

    • Locate the oven temperature sensor, usually positioned at the back of the oven.
    • Check for any visible damage or signs of wear.
    • Ensure the sensor is securely connected to the oven.
  2. Examine the Harness:

    • Follow the wiring harness from the sensor to the control board.
    • Look for loose connections or damaged wires.
    • Repair or replace any compromised components.
  3. Consider Second Board Replacement:

    • If the temperature sensor and harness appear intact, the issue may lie with the second board.
    • Consult your appliance’s manual for guidance on replacing the second board.
    • Exercise caution and, if needed, seek professional assistance for a precise replacement.

Note: Error codes are designed to pinpoint specific issues, making the troubleshooting process more efficient. Regular maintenance and timely resolution of error codes contribute to the longevity and optimal performance of your appliance.


Navigating through Error Code FR involves a systematic examination of the oven temperature sensor, harness, and, if necessary, the second board.
