What it is

The thermostat (ET) is a temperature-sensing control component manufactured by Johnson & Starley for use on Celsia and B Gas appliances. It monitors temperature and signals the appliance to bring the heating on or off to hold the set condition. It is fitted across the Hispec range of warm air units.

Signs this part needs replacing

  • The appliance does not respond to changes in room or return air temperature
  • Heating runs continuously or short-cycles regardless of the setting
  • Room temperature drifts noticeably away from the thermostat setpoint
  • The warm air unit fails to fire or locks out intermittently
  • Temperature control is erratic or inconsistent between cycles

Before you order

  • Check the appliance data badge to confirm the model matches the fit list
  • Confirm the existing thermostat is the ET type used on Celsia and B Gas variants
  • Note the part number on the component being removed before ordering
