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

  1. Power off the oven at the circuit breaker for at least 1 minute to reset controls.
  2. Visually inspect the oven temperature sensor through the oven interior (usually a thin probe in the back) and wiring harness for obvious damage.
  3. Ensure all accessible connectors are fully seated and free of corrosion or loose pins.

Technician Only Diagnostics and component testing

  1. 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.
  2. Inspect and continuity‑check the wiring harness between the sensor and control/PRB.
  3. 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)

🛑 When to Call a Pro:
  • If you’re unable to safely access internal components or lack multimeter/testing skills
  • If FF persists after verifying sensor and wiring harness condition
