What it is
The Ferroli 39817600 is a 100°C security thermostat kit for Ferroli gas boilers. It is a safety cut-out that interrupts the boiler's operation when the sensed temperature reaches 100°C. It sits in the thermostats category of the Ferroli gas boiler spares range.
Signs this part needs replacing
- The boiler locks out and needs a manual reset, often after a heating or hot water cycle.
- The boiler fails to fire, or cuts out before reaching its normal operating temperature.
- Repeated overheat lockouts occur with no other obvious cause in the system.
- The boiler runs briefly and then shuts down, with the same fault returning after each reset.
- An overheat fault is shown on the boiler controls or display.
Before you order
- Confirm your boiler model and GC number against the fitment list above.
- Check that the part number on the existing thermostat matches 39817600.
- Confirm whether your appliance uses this kit or a different thermostat variant.
- Isolate the electrical supply and gas before fitting, and work to the manufacturer's instructions.
