What it is

Fan control switch for Johnson & Starley warm air units, supplied under part number BOS00104. It uses the Honeywell L4068C control rather than the MAF variant, and governs the running of the appliance fan.

Signs this part needs replacing

  • The fan fails to start when there is a call for heat
  • The fan runs continuously and will not shut down
  • Fan operation is intermittent or cuts in and out during a cycle
  • The appliance locks out or overheats because the fan is not being switched correctly
  • No warm air output despite the appliance firing

Before you order

  • Confirm whether your appliance uses the Honeywell L4068C control or the MAF variant, as the two are not interchangeable
  • Check the appliance model and GC number against the manufacturer's parts list
  • Inspect the existing control for its Honeywell model marking before ordering
