What it is

The Glow-worm 0020053614 is an air pressure switch used on Glow-worm Micron FF gas boilers. It monitors the pressure created by the combustion fan and proves airflow before the boiler is allowed to fire. The switch supersedes the earlier code S227032.

Signs this part needs replacing

  • Boiler locks out or fails to fire, with the fan running but no ignition sequence
  • Repeated lockout on start-up that clears intermittently
  • Fan proving fault indicated by the boiler's fault code or diagnostic display
  • Boiler fires briefly then shuts down as the pressure signal drops out
  • No continuity change at the switch when the fan is running

Before you order

  • Confirm the boiler model is a Glow-worm Micron 30FF or Micron 40FF
  • Check the existing switch part number against 0020053614 before ordering
  • Verify the fault is with the switch rather than the fan, tubing or flue path
  • Inspect the pressure sensing tubes and connections for blockage or splits
