What it is

The top panel lid assembly is a casing component manufactured by Potterton for the Promax range. It forms the upper closure of the appliance casing, covering the top of the boiler or cylinder store. It is supplied under part number 5120121.

Signs this part needs replacing

  • The top panel is dented, bent or distorted so it no longer sits flat on the casing
  • Visible corrosion or rust along the panel edges or fixing points
  • The panel is loose or will not secure correctly to the appliance casing
  • Paint or coating has flaked away, leaving exposed metal
  • The panel has been removed and damaged during servicing or access work

Before you order

  • Confirm the appliance model against the fitment list above
  • Check the serial number prefix where a cylinder variant is listed
  • Verify the existing panel is the top lid assembly and not another casing section
  • Have the appliance model and serial number to hand before ordering
