What it is

The Glow-worm 0020053616 is an air pressure switch used on Glow-worm Micron FF gas boilers. It monitors the pressure created by the combustion fan and confirms airflow before the boiler is allowed to proceed to ignition. The switch is a safety-critical component in the appliance's fan and flue proving circuit.

Signs this part needs replacing

  • The boiler locks out on start-up even though the fan runs.
  • Repeated lockouts that clear on reset and then return.
  • The fan runs but the boiler does not progress to ignition.
  • Intermittent operation that changes with flue or fan behaviour.
  • A switch that fails to change state when the fan is running, confirmed by meter testing.

Before you order

  • Confirm the boiler model is a Glow-worm Micron 60FF or Micron 80FF.
  • Check the GC number on the appliance data badge against your model.
  • Compare the part number on the existing switch with 0020053616, and note the earlier code S227053.
  • Check the fan and flue for blockage or restriction before condemning the switch.
