Possible Causes
NTC sensor reading too hot or too cold, sensor not seated properly in tub, wiring short or open, control misreading sensor
How to Fix / Troubleshooting
Safety first: Unplug the unit before accessing the heater area.
Step-by-step checks:
- Check sensor seating: Ensure the NTC is fully inserted into its well or bracket on the tub or heater housing and has good thermal contact.
- Test resistance: Measure NTC resistance at room temperature and compare to spec. Also, gently warm the sensor (e.g., with your hand) and confirm resistance changes smoothly.
- Inspect wiring: Look for pinched or rubbed-through wires that could short to chassis or each other.
When to replace: Replace the NTC if it does not respond correctly to temperature changes. If the sensor is good, suspect the main control board.
