What it is

The Potterton 5142147 is a reset switch supplied as a spare for Potterton Commercial gas boilers. It sits on the appliance control panel and is used to clear a lockout condition and return the boiler to normal operation. It is a direct panel-mounted component for the Potterton Commercial Sirius FS range.

Signs this part needs replacing

  • The boiler stays in lockout after the reset button is pressed.
  • The button feels loose, does not return, or requires excessive force to operate.
  • Reset only works intermittently, with the appliance locking out again shortly after.
  • Visible damage, cracking or scorching around the switch body or its terminals.
  • Continuity across the switch contacts cannot be confirmed when the button is operated.

Before you order

  • Confirm the appliance model is a Potterton Commercial Sirius FS 400 or Sirius FS 525.
  • Check the existing switch part number against 5142147 before ordering.
  • Isolate the electrical supply to the boiler before removing or fitting the switch.
  • Inspect the panel wiring and connections for damage that may have caused the original fault.
