What it is

The Johnson & Starley 1000-0520860 is an air pressure switch used on Economaire warm air units. It monitors air pressure within the appliance's air circuit and signals the control system when the required pressure is present. It is a serviceable component within the appliance's safety and ignition sequence.

Signs this part needs replacing

  • The appliance fails to fire and locks out even though the fan runs
  • Repeated lockouts on start-up that clear after a reset, then return
  • The fan runs but the ignition sequence does not progress
  • Intermittent operation that varies with flue or air path conditions
  • Fault indication relating to air pressure or airflow proving

Before you order

  • Check the appliance rating plate to confirm the model and GC number
  • Confirm the part number on the existing switch matches 1000-0520860
  • Inspect the pressure sensing tubes and electrical connections for damage or blockage before replacing the switch
  • Confirm the appliance is isolated from the electrical and gas supply before any work
