JennAir oven displays F2-1, often when attempting to bake or broil.

Safety: If the oven is overheating, turn off the breaker immediately and allow it to cool completely.

• Confirm overheating: If possible, use an oven thermometer to compare the actual temperature to the set temperature. If the oven is much hotter than set, suspect the sensor or control.
• Check sensor resistance: With power off, test the oven temperature sensor at room temperature (around 1050–1100 ohms). A significantly lower reading can cause the control to overheat the oven.
• Inspect control relays: Access the control board and check if the bake or broil relay contacts are welded closed (signs of heat damage or charring).
• Replace faulty parts: Replace the oven sensor if out of spec. If the sensor is correct but the oven still overheats or F2-1 persists, replace the EOC.
• Recalibrate (if available): Some JennAir models allow temperature calibration in the settings menu. After replacing parts, adjust calibration if the oven is consistently off by a small amount.
