What it is

This is an Alpha cable assembly, part number 1.030891, used on Alpha gas boilers. It carries the wiring for the spark generator, pump, diverter valve and flame sensing electrode. The loom connects these components to the boiler's control PCB.

Signs this part needs replacing

  • Boiler fails to light, with no spark at the electrode
  • Diverter valve or pump does not run when demanded
  • Flame sensing fault or repeated lockout on the PCB
  • Cracked, chafed or heat-damaged insulation on the loom
  • Intermittent faults that clear when the cable is moved

Before you order

  • Check your boiler model against the fit list above
  • Confirm the part number on the existing cable or boiler data label
  • Inspect the connector plugs and pin count against the cable being removed
  • Check the routing and any retaining clips for damage before refitting
