Jenn-Air Oven Error Code F2

F2 on a Jenn-Air oven means the electronic control board has detected an over-temperature condition. The control monitors the oven through a temperature sensor (RTD probe) and shuts the oven down when the sensed temperature exceeds its programmed safety limit. The cause is usually a failed temperature sensor, though a faulty control board or wiring issue can also produce this code.

Start by unplugging the oven and ohm-testing the oven temperature sensor. Disconnect the sensor leads and measure resistance with a multimeter; the reading should be close to 1080 ohms at room temperature. If the sensor reads open, shorted, or significantly out of range, replace the sensor. If the sensor tests good, inspect the wiring harness for damage, then replace the electronic control board if wiring is intact.

Yes, a faulty oven temperature sensor is the most common cause of F2. When the sensor fails, it can send a resistance value to the control board that corresponds to an extremely high temperature, causing the board to trigger F2 even though the oven cavity is at normal or ambient temperature. Testing the sensor with a multimeter set to ohms is the first step in diagnosing this code.

No, you should not use the oven while F2 is active. The code indicates either a genuine over-temperature condition or a sensor failure that prevents the control from accurately monitoring oven temperature. Operating the oven without reliable temperature control creates a risk of overheating, food burning, or damage to the oven cavity and components. Diagnose and repair the fault before using the oven again.

An oven temperature sensor for a Jenn-Air typically costs $20 to $60 for the part, and replacing it is a beginner-level DIY repair requiring only a screwdriver. If the control board is the cause, the board itself usually runs $150 to $350 depending on the model, with professional labor adding another $100 to $200. Diagnosing the sensor first with an ohm test is the correct sequence since sensors fail far more often than control boards.
