What it is
The Alpha 3.018276 is a cable assembly serving the temperature sensors, air pressure switch (APS), flow switch and gas valve modulator on Alpha HE Sy25 (LPG) appliances. It carries the sensor and switch signals between these components and the boiler's control board. It is listed as a single cable part for this appliance.
Signs this part needs replacing
- Boiler locks out or fails to ignite, with an APS or fan-related fault code.
- Intermittent or no response to heating or hot water demand.
- Erratic temperature readings, overheating or short cycling.
- Flow switch not registering demand, so the boiler does not fire.
- Chafed, brittle or corroded cable and connectors at the sensor, switch or modulator.
Before you order
- Confirm the appliance is an Alpha HE Sy25 (LPG), as this part is listed for that variant.
- Check the part number on the existing cable or connector against 3.018276.
- Inspect the connectors and terminals for corrosion or damage before fitting.
