What it is

The Heatline low pressure switch is a sensing component used across a range of Heatline gas boilers. It monitors pressure within the appliance circuit and signals the control board when pressure falls outside the required range, preventing the boiler from firing under unsafe conditions. It is listed under switches within gas boiler spares.

Signs this part needs replacing

  • Boiler fails to fire or repeatedly goes to lockout
  • Intermittent ignition or cycling on and off without a demand change
  • No heating or hot water despite the system holding correct pressure
  • Fault code relating to pressure or water pressure appearing on the display
  • Boiler unresponsive to a call for heat from the programmer or thermostat

Before you order

  • Check your boiler model against the fit list above, as compatibility varies across the Heatline range
  • Confirm the manufacturer code on the existing switch matches 3003200038
  • Verify the system pressure with a gauge before replacing the switch, as low pressure may be a system fault rather than a switch fault
  • Check the GC number on the appliance data badge where one is shown
