What Does Error FF Mean?
The JennAir Oven FF error indicates a malfunction related to the temperature sensor, leading to inaccurate temperature readings or a failure to heat. This error suggests that the temperature feedback signal is outside expected parameters, potentially due to a faulty oven temperature sensor, a loose or damaged wiring harness, or a malfunctioning power relay board (PRB). If the error persists, further investigation is needed.
Common Symptoms:
- Oven displays FF shortly after attempting to use bake or other heating functions. [AppliancePartsPros Forum](
- Cooling fan may run continuously following the FF error before code appears. [AppliancePartsPros Forum](
Possible Causes
- Faulty oven temperature sensor (RTD) (medium)
- Loose or damaged wiring harness between sensor and control/PRB (medium)
- Malfunctioning power relay board (PRB) (medium)
How to Fix Error FF
DIY Fix Basic visual inspection and reset
- Power off the oven at the circuit breaker for at least 1 minute to reset controls.
- Visually inspect the oven temperature sensor through the oven interior (usually a thin probe in the back) and wiring harness for obvious damage.
- Ensure all accessible connectors are fully seated and free of corrosion or loose pins.
Technician Only Diagnostics and component testing
- Disconnect power and access the oven control area to test the oven temperature sensor resistance with a multimeter to verify it’s within specification for that model.
- Inspect and continuity‑check the wiring harness between the sensor and control/PRB.
- Test or replace the power relay board if the sensor and harness test normal but the invalid reading persists.
Parts needed: Oven temperature sensor, Wiring harness, Power relay board (PRB)
- If you’re unable to safely access internal components or lack multimeter/testing skills
- If FF persists after verifying sensor and wiring harness condition
