Jenn-Air Oven Error Code F3 — Oven Temperature Sensor Open Circuit
What this means
Error F3 on Jenn-Air ovens indicates the Electronic Oven Control (EOC) board has detected an open circuit in the oven temperature sensor (RTD probe). This means the sensor wire is broken, disconnected, or the sensor element itself has failed. Without temperature feedback, the oven cannot regulate heat and will not allow the oven to operate. This code commonly appears after self-clean cycles (which stress the sensor at extreme temperatures) or when the sensor wiring has been damaged.
Alternate codes: F3-E0, F3E0
Step-by-step fix
3 stepsCheck the sensor wire harness connection
Turn off the oven breaker. Access the oven temperature sensor probe — its wire harness typically exits through the rear wall of the oven cavity. Check where the sensor wires connect to the main harness. Reseat the connector firmly. Look for any burn damage or breaks in the wire.
On Jenn-Air wall ovens, the sensor connector may be behind the oven, requiring you to slide the oven forward in its cavity slightly.
Test the sensor resistance
Disconnect the sensor from the wire harness. Set a multimeter to the 20K-ohm range. Measure resistance across the sensor leads. At room temperature, it should read approximately 1080–1100 ohms. An OL (open) reading confirms the sensor has failed and needs replacement.
Also check for continuity between each sensor lead and the metal probe housing — there should be no continuity (no short to ground).
Replace the oven temperature sensor
Remove the one or two screws securing the sensor probe inside the oven cavity. Carefully pull the probe out through the rear wall. Feed the new sensor in from inside the cavity, reconnect the wire harness, and secure the mounting screws. Restore power and test.
The sensor probe should not touch the oven walls or racks — ensure it is positioned with clearance on all sides for accurate readings.
When to call a professional
If the new sensor also triggers F3, there may be a break in the wire harness between the sensor and the EOC board. A technician can trace and repair the wiring.
