What it is

The electrical box with viewing window is a Potterton Commercial enclosure that houses electrical components on the boiler and allows the controls or display behind it to be read through the window. It is supplied under manufacturer part number 5141434 and is listed for the Potterton Commercial Sirius 2 WH range of commercial gas boilers. The window keeps the enclosed components covered while still allowing visual checks without removing the box.

Signs this part needs replacing

  • The viewing window is cracked, scratched or too cloudy to read the display or indicators behind it
  • Condensation or moisture is trapped behind the window
  • The enclosure is cracked, distorted or no longer fixes securely to the appliance
  • Discolouration or heat marking is visible on the box or around the window

Before you order

  • Confirm the appliance model from the boiler data badge is one of the Sirius 2 WH models listed above
  • Check the existing electrical box and window for physical damage before ordering
  • Match the manufacturer part number 5141434 against the number on the existing component
  • Isolate the appliance electrically before removing or refitting any enclosure covering electrical parts
