What Does Error FR Mean?
The JennAir Oven FR error code indicates a fault in the temperature sensing circuit of the second oven, typically the lower one. This error often results in erratic temperature readings or prevents the oven from heating altogether. Symptoms include the FR code displaying on the control panel, continuous beeping, and normal operation of the upper oven while the lower is affected.
Common Symptoms:
- FR displays on oven control panel when attempting to heat/start second oven (often lower oven).
- Oven beeps continuously and does not proceed to heat.
- Upper oven may operate normally while lower shows FR.
Possible Causes
- Faulty or disconnected oven temperature sensor in second oven (medium)
- Damaged or loose wiring harness between sensor and control boards (medium)
- Malfunction of the second oven control/relay board (medium)
How to Fix Error FR
DIY Fix Basic checks and reset
- Turn off the oven and disconnect power at the circuit breaker for 1–2 minutes.
- Turn power back on and attempt to clear the error.
- Ensure the oven door is fully closed and no buttons are stuck.
DIY Fix Inspect temperature sensor and connections
- Locate the temperature sensor in the affected oven cavity (usually at the rear).
- Visually inspect the sensor and harness for disconnection, burn marks, or obvious damage.
- If accessible and safe, ensure the connector is seated firmly.
Technician Only Test and replace temperature sensor or control board
- Disconnect power to the oven.
- Remove access panels to reach the oven temperature sensor and wiring harness.
- Use a multimeter to measure the resistance of the sensor (approx. ~1100 ohms at room temperature expected).
- If out of specification or intermittent, replace the sensor.
- If sensor and wiring test normal, test the second oven relay/control board for faults and replace as needed.
Parts needed: Oven temperature sensor (RTD), Wiring harness, Second oven control/relay board
- If after inspecting and securing connectors the FR code persists.
- If you are not comfortable performing multimeter testing or internal inspections.
- If replacing parts does not clear the error code.
