What it is
The Alpha 3.019005 is a cable assembly used on Alpha gas boilers. It carries the wiring connections for the fan, the 24V transformer, the temperature sensor, the pressure switch and the flow switch. It sits within the boiler's wiring loom and provides the electrical link between these components and the control system.
Signs this part needs replacing
- The fan runs intermittently or fails to start despite the boiler calling for heat
- Fault codes relating to the fan, temperature sensor, pressure switch or flow switch appear
- Visible damage to the cable, such as chafed insulation, scorching or exposed conductors
- Loose, corroded or brittle connectors at any of the component plugs
- Continuity faults traced through the loom during electrical testing
Before you order
- Confirm your boiler model against the fit list above
- Check the GC number on the appliance data badge matches your model variant
- Inspect the existing cable and connectors to confirm the fault lies with the assembly rather than an individual component
- Isolate the electrical supply before removing or fitting any wiring
