What it is
This is a cable assembly for Alpha gas boilers, carrying the wiring between the NTC temperature sensor and the air pressure switch. It is supplied under Alpha part number 3.013463 and is listed for the CB24X and CB28X LPG appliance variants. The harness provides the electrical connection these two components need to report temperature and pressure status back to the boiler controls.
Signs this part needs replacing
- Boiler locks out or fails to fire with a sensor or air pressure fault code logged
- Intermittent temperature readings or erratic boiler modulation
- Air pressure switch proving faults that persist after the switch itself is tested
- Visible damage to the cable, such as chafing, scorching, cracked insulation or exposed conductors
- Loose, corroded or heat-damaged plug terminals at either end of the harness
Before you order
- Confirm the boiler model is a CB24X or CB28X LPG variant
- Check the existing harness part number against 3.013463
- Inspect the sensor and air pressure switch terminals before ordering, in case the fault lies with those components rather than the cable
- Verify the fault code or symptom points to the sensor or air pressure switch circuit
