What it is

The 1000-0511760 is a relay printed circuit board assembly manufactured by Johnson & Starley. It is used in Hispec warm air units, where the relay stage switches the fan and heating circuits in response to control demand. The board is supplied as a complete assembly for service replacement.

Signs this part needs replacing

  • Relay chatter or repeated clicking from the board when there is a call for heat
  • Fan or burner failing to start despite a confirmed control demand
  • Intermittent operation, with the appliance cutting in and out at random
  • Visible burning, pitting or discolouration at the relay contacts or board tracks
  • No response from the appliance to thermostat or control input

Before you order

  • Confirm the appliance model and GC number against the fitment list above
  • Check the part number printed on the existing board matches 1000-0511760
  • Inspect the wiring loom and plug connections for damage before fitting a new board
