What it is

The Ferroli 39818370 is a wet-type temperature sensor supplied with a 1 metre lead. It is fitted to appliances in the Ferroli Sigma range and is used to sense water temperature and report it back to the boiler's control board. Trade references list it as an NTC sensor, and it supersedes the earlier code 806051.

Signs this part needs replacing

  • Erratic or implausible temperature readings on the boiler display
  • Boiler short-cycling or failing to hold a steady flow temperature
  • Domestic hot water temperature fluctuating or running cold
  • Lockout or fault codes relating to temperature sensing
  • Resistance reading at the sensor outside the expected range for the appliance

Before you order

  • Confirm your appliance model against the fit list above
  • Check the lead length required on your appliance matches the 1 metre lead
  • Check the connector type on the existing sensor matches before ordering
  • Confirm the sensor designation on your appliance's parts list
