What it is

The Ranco CL6P0144-000 is a thermostat control supplied by Glow-worm for its 45 and 56 series back boiler units and BBU appliances. It regulates the appliance's operating temperature by switching the burner in response to the sensed water or system temperature. The control is listed under Glow-worm part code S202518 and replaces the earlier code 202518.

Signs this part needs replacing

  • The boiler fails to fire or shut down at the set temperature.
  • The appliance cycles on and off erratically regardless of the dial position.
  • The control knob turns without any resistance or audible click.
  • Heating output stays constant, with no response to temperature adjustment.
  • The boiler overheats or produces no heat at all.

Before you order

  • Confirm your appliance model against the fit list above.
  • Check the existing thermostat's part number or code before ordering.
  • Verify the control type and mounting arrangement match the appliance.
  • Isolate the appliance's electrical supply before any work.
