What it is

The FAN & LIMIT THERMOSTAT (ET) is a combined fan and limit thermostat manufactured by Johnson & Starley for use on Hispec warm air units. It controls fan operation in response to appliance temperature and provides a high-limit safety cut-out to protect the unit from overheating. It is supplied under part number 1000-0515455.

Signs this part needs replacing

  • The circulating fan runs continuously, regardless of call for heat
  • The fan fails to run when the unit reaches operating temperature
  • The unit repeatedly locks out or trips on the limit stat
  • Fan operation becomes erratic, cycling on and off as the appliance warms
  • No warm air output despite the appliance firing

Before you order

  • Confirm the appliance model and GC number against the fitment list above
  • Check the existing thermostat part number and confirm it is 1000-0515455
  • Verify the thermostat is the ET variant, as fitted to Hispec units
  • Ensure the appliance is isolated and any gas-related work is carried out by a competent person
