Alpha E-Tec 28 Main PCB – Refurbished | Part No. 1.037031

When an Alpha E-Tec 28 boiler fails to ignite, displays persistent error codes, shuts down unexpectedly, or loses control of heating functions, the PCB (printed circuit board) is very frequently the root cause. The Alpha E-Tec 28 Main PCB (Part No. 1.037031) is a refurbished direct replacement that restores full electronic control of your boiler — resolving ignition faults, lockouts, and erratic behaviour in one straightforward component swap.

This PCB is the central brain of your Alpha E-Tec 28 boiler, managing ignition sequences, fan operation, sensor monitoring, heating demand, and all safety interlock functions. Each refurbished unit is professionally tested and verified to confirm reliable performance before dispatch.

Available in three service options: Repair/Exchange (send your faulty board for repair), Advance Replacement (receive a replacement before returning your faulty unit — minimising downtime), or Direct Sale (buy a ready-to-install refurbished board outright).
