What it is
The main wiring harness is the internal loom that carries power and control signals between the major electrical components of an Alpha boiler. It connects the printed circuit board to the fan, pump, gas valve, sensors and user controls through a set of moulded plugs and terminals. This is the Alpha 1041381 harness, listed by the manufacturer under the Alpha brand.
Signs this part needs replacing
- The boiler intermittently loses power or fails to fire with no obvious fault at the PCB
- Error codes appear and clear at random, particularly after the casing has been disturbed
- Visible scorching, brittleness or cracked insulation on one or more harness conductors
- Loose, corroded or heat-damaged spade terminals and plug connectors
- Continuity faults traced along the loom during electrical testing
Before you order
- Confirm the boiler model and GC number from the data badge, then check them against the compatibility list on this page
- Compare the connector layout and pin count of the existing harness with the replacement before fitting
- Isolate the electrical supply at the fused spur and follow the manufacturer's wiring diagram when refitting
- Inspect the PCB and component plugs for damage that may have caused the original harness fault
