What it is

The Potterton Button On/Off Wiring, part number 5138699, is the switching assembly and associated wiring for the on/off control on Potterton Commercial appliances. It is used on boiler models within the Potterton Commercial range to provide the manual on/off input to the control circuit.

Signs this part needs replacing

  • The boiler does not respond when the on/off button is pressed
  • The button must be pressed repeatedly or held down before the appliance switches
  • The button feels loose, stuck or fails to return after being pressed
  • Switching is intermittent, with the appliance cutting in and out without a clear input
  • Visible damage or a broken connection on the button wiring

Before you order

  • Confirm the appliance model is one of the Sirius SAT variants listed above
  • Check the existing button and wiring against part number 5138699 before ordering
  • Isolate the electrical supply to the appliance before any inspection or fitting work
  • Inspect the connector and wiring route for damage that may also need attention
