What it is

The Saunier Duval 05641400 is a temperature sensor (thermistor) for the TWIN F28E gas boiler. It monitors temperature within the appliance and feeds the reading back to the boiler's control system. The sensor is manufactured by Saunier Duval as a spare part for this model.

Signs this part needs replacing

  • Boiler locks out or displays a temperature-related fault code
  • Erratic or inaccurate temperature readings from the boiler
  • Boiler short-cycles or fails to reach the set temperature
  • Domestic hot water temperature fluctuates unexpectedly
  • Sensor resistance measures outside the manufacturer's tolerance when tested

Before you order

  • Confirm your boiler is a Saunier Duval TWIN F28E (GC 47-920-42)
  • Check the part number on the existing sensor matches 05641400 or 5641400
  • Consult the manufacturer's parts list if you are unsure of compatibility
