What it is

The Ferroli 100°C manual reset thermostat (part number 39813600) is a limit thermostat fitted to a wide range of Ferroli domestic and commercial boilers. It monitors appliance temperature and trips at its set point to shut the boiler down, remaining open until it is reset by hand. It replaces Ferroli code 800145.

Signs this part needs replacing

  • The boiler locks out and will not restart until the reset button is pressed
  • The appliance cuts out again shortly after each reset as it heats up
  • Overheating or kettling before the boiler shuts down
  • No heating or hot water because the thermostat has tripped and stays open
  • The reset button feels loose, sticks, or fails to latch

Before you order

  • Check your boiler model against the fit list above before ordering
  • Confirm the existing thermostat's trip temperature and reset type match this part
  • Inspect the wiring and terminal connections at the thermostat before fitting
