What it is

The Valor thermoswitch and leads is a boiler temperature-sensing switch supplied as a switch and lead assembly. It is fitted to the Valor Black Beauty Oxysafe boiler, where it monitors boiler temperature and signals the controls as heat is demanded. It is a Valor spare part intended for servicing and repair of the appliance.

Signs this part needs replacing

  • The boiler fails to fire when heat is demanded
  • The boiler overheats or repeatedly goes to lockout
  • The burner cycles on and off erratically during a heating cycle
  • Temperature control no longer responds as expected
  • Leads at the switch are damaged, brittle or disconnected

Before you order

  • Confirm the appliance is the Valor Black Beauty Oxysafe, Model 466
  • Compare the existing thermoswitch and its lead connections against the replacement before fitting
  • Isolate the electrical supply to the boiler before removing the old part
