What it is

The Potterton 7745954 Pressure Sensor is a pressure sensing component used on Potterton Commercial Sirius 2 and Sirius 3 boilers. It forms part of the boiler's pressure monitoring circuit, providing the control system with a signal that reflects system pressure. It is supplied as a single component for replacement during service or repair.

Signs this part needs replacing

  • Boiler locks out or shuts down with a pressure-related fault code
  • Pressure reading at the controls does not match the actual system pressure
  • Pressure gauge or display behaves erratically or gives no reading at all
  • Intermittent operation that traces back to the pressure sensing circuit

Before you order

  • Confirm the appliance model matches one of the Sirius 2 or Sirius 3 variants listed above
  • Check the part number on the existing sensor against 7745954
  • Verify the fault is traced to the pressure sensor rather than the pressure gauge, wiring or control board
  • Confirm you have the correct access and isolation procedure for the appliance before starting work
