What it is

The S202232 is an air pressure switch fitted to Glow-worm Micron 100FF and Ultimate 100FF boilers, manufactured by Honeywell as the C6065A1366:2. It is a safety device that confirms the combustion fan is running correctly before the boiler is allowed to fire.

Signs this part needs replacing

  • Boiler locks out on ignition or fails to fire
  • Intermittent lockouts that clear on reset then recur
  • Fault code relating to fan or air pressure proving
  • Fan runs but boiler will not proceed to ignition

Before you order

  • Match the part number printed on your existing switch
  • Isolate electrical power before replacing
  • Have your boiler make, model and GC number ready to confirm fitment
  • This is a safety-critical part; installation should be carried out by a Gas Safe registered engineer
