What it is
The Glow-worm S202201 is an air pressure switch supplied as a serviceable spare for Glow-worm domestic gas boilers. It senses the pressure difference produced by the combustion fan and signals the control board that airflow is present, allowing the boiler to proceed to ignition. A failed switch typically stops the boiler firing or causes repeated lockouts.
Signs this part needs replacing
- The fan runs but the boiler will not fire and goes to lockout.
- Repeated lockouts that clear on reset and then return.
- A fault code on the boiler display pointing to a fan or air pressure fault.
- The boiler fails to fire from cold but runs normally once reset.
- Intermittent operation, particularly in windy conditions or where the flue or air intake is restricted.
Before you order
- Confirm the part number S202201 against the switch fitted to the appliance.
- Check the GC number and model on the data badge to confirm the boiler variant.
