What it is

The Potterton 5120209 Control LMU is a printed circuit board (PCB) that controls the operation of Potterton Commercial boilers rated at 60 kW. It is the main control board for appliances built up to serial number 810XXXX, handling the boiler's control and safety functions. The board is supplied as a spare for the Potterton Commercial range.

Signs this part needs replacing

  • Boiler does not fire or gives no response when there is a demand for heat
  • Lockout or fault codes shown on the boiler controls that cannot be cleared
  • Intermittent or erratic burner operation
  • No display or loss of power at the boiler control panel
  • Boiler fails to modulate or cycles incorrectly

Before you order

  • Confirm the appliance serial number is below 810XXXX, as this board is specified for units up to that serial number
  • Confirm the boiler is a Potterton Commercial Paramount TWO rated at 60 kW
  • Check the part number on the existing control board against 5120209
  • Isolate the electrical supply to the boiler before removing or fitting the board
