What it is
The Hamworthy 573405253 is a limit thermostat used on Hamworthy Lilliput floor standing gas boilers. It monitors boiler temperature and interrupts the burner circuit when the set limit is exceeded, protecting the appliance from overheating. It is a safety-related control within the boiler's thermostat range.
Signs this part needs replacing
- The boiler locks out or shuts down before reaching the set temperature
- Repeated overheat trips that need manual resetting
- No heating or hot water because the burner circuit is held open
- The boiler fires briefly and then cuts out
- A fault code indicating an overheat or limit thermostat trip
Before you order
- Confirm the appliance is a Hamworthy Lilliput HE40, HE65 or HE90 floor standing boiler
- Check the part number on the existing thermostat against 573405253
- Isolate the electrical supply before removing or fitting the thermostat
- Verify the fault lies with the limit thermostat and not another safety device
