Possible Causes

Loose NTC sensor on heater body, Damaged sensor wiring, Faulty NTC temperature probe, Poor thermal contact between sensor and heater

How to Fix / Troubleshooting

Safety: Unplug and allow the heater to cool fully before touching any components.

  • Locate NTC sensor: Find the NTC temperature sensor clipped or bonded to the in-line heater or water path.
  • Check mounting: Ensure the sensor is firmly attached to the heater surface with its clip or thermal compound. Re-secure if loose.
  • Inspect wiring: Follow the sensor leads back to the PCB. Look for chafed insulation or broken conductors, especially near bends.
  • Measure resistance: At room temperature, measure the NTC resistance and compare with service data. If it reads open or short, replace the sensor.

Incorrect sensor readings can cause overheating; if unsure, have a technician verify heater control operation.
