What it is

The Baxi 720841701 is a printed circuit board (PCB) supplied in the NG keyed variant for Baxi Neta-Tec and Neta-Tec Plus gas combi boilers. It is the main control board, handling ignition sequencing, gas valve and fan control, pump and heating circuit management, and the appliance's safety interlocks. The board is a direct replacement item for the listed Neta-Tec and 128 ErP Combi models.

Signs this part needs replacing

  • Repeated lockouts, intermittent shutdowns or erratic fan and pump behaviour.
  • Error or fault codes displayed on the boiler control panel that point to board or ignition faults.
  • Visible damage to the board, such as scorching, burnt tracks, swollen capacitors or corrosion.
