Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the appliance and allow any hot water to cool before working near the heater area.
- Locate the NTC: The temperature sensor is usually mounted in or near the heater housing on the outer tub. Access from the rear or bottom depending on model.
- Check wiring: Inspect the connector and wires to the NTC for damage, corrosion, or loose fit. Reseat the connector firmly.
- Visual inspection: Look for signs of overheating or cracking on the sensor body.
- Resistance test (for advanced users): With the sensor disconnected, measure resistance with a multimeter. Typical NTC values are around 20kΩ at room temperature (exact spec in JennAir service data). If reading is open, shorted, or far out of range, replace the sensor.
- Replace NTC if faulty: Remove the retaining clip or bracket, pull out the sensor, and install the new JennAir-compatible NTC, ensuring a snug fit and proper sealing.
When to call a technician: If the NTC tests good but F05 persists, the main control board may be defective and should be checked by a professional.
