Possible Causes

Shorted or open NTC sensor, wiring short to ground, heater overheating water, control misreading temperature

How to Fix / Troubleshooting

Safety first: Disconnect power and allow hot water to cool.

  • Inspect NTC sensor: Access the wash heater area and locate the NTC. Check for damage or loose connection.
  • Check wiring harness: Look for pinched, frayed, or burnt wires between the NTC and control board.
  • Test sensor: Measure resistance at room temperature and compare to JennAir specifications. Replace if out of range or intermittent.
  • Re-test cycle: After replacing the sensor or repairing wiring, run a warm wash and monitor for F24.

When to call a technician: If the sensor and wiring are good, the control board may be faulty and should be evaluated by a technician.
