What it is

The Potterton 5132157 terminal block is a six-pole terminal board used in Potterton Commercial boiler appliances. It provides the connection point for the wiring within the boiler's electrical assembly. This is a manufacturer part carrying the reference 5132157.

Signs this part needs replacing

  • Visible discolouration, charring or scorching around one or more terminals.
  • A terminal that has become loose, cracked or brittle, so the wiring will not clamp securely.
  • Intermittent electrical faults or loss of supply at the boiler that can be traced to a poor connection on the block.
  • Overheating or a burning smell local to the terminal area.

Before you order

  • Confirm the appliance model against the fit list above and check the boiler's own data plate.
  • Check the existing terminal block to confirm it has the same pole count and terminal layout.
  • Isolate the electrical supply and prove dead before removing or inspecting any wiring.
  • Note the position of each conductor before disconnecting, so the wiring can be reinstated correctly.
