What it is

The Morco Products Return Thermistor (ICB128001) is a temperature sensing component used on Morco GB series LPG boilers. It is fitted to the return circuit and provides a temperature signal to the boiler's control system. The part number for this item is ICB128001.

Signs this part needs replacing

  • Boiler locks out or fails to fire, with a fault code pointing to the return sensor
  • Temperature readings that do not match actual system conditions
  • Short cycling or unstable boiler operation as the control responds to a faulty signal
  • Resistance readings from the thermistor that fall outside the values expected for the measured temperature
  • Physical damage, corrosion or a loose or damaged connection at the sensor

Before you order

  • Confirm the appliance model matches one of the fit lines above
  • Check the existing thermistor carries the part number ICB128001
  • Inspect the sensor body, its wiring and its connection for damage before ordering
  • Confirm the fault is with the return thermistor rather than another sensor or component in the circuit
