Alpha CB24X / CB28X / HE Series Boiler PCB – Refurbished | Part No. 1.025576

Boiler lockout, no ignition, repeated fault codes, or loss of heating and hot water on an Alpha CB or HE series boiler are strong indicators of PCB failure. The control board manages all critical boiler functions — including ignition sequencing, gas valve control, pump operation, modulation, and safety monitoring. When it fails, the entire system becomes unreliable. The Alpha CB24X / CB28X / HE Series Boiler PCB (Part No. 1.025576 / 1.017658) is the correct OEM-specification replacement for a wide range of Alpha CB and HE models, restoring full electronic control and resolving persistent fault codes.

This is a professionally refurbished genuine Alpha PCB. Each board is inspected, function-tested, and calibrated against original manufacturer specifications before dispatch, providing proven performance at a substantially lower cost than a brand new board.
