Worcester Greenstar 28i Junior HE PCB – Refurbished | Part No. 87483006500 87483006340

The printed circuit board is the central intelligence of your Worcester Greenstar boiler — coordinating ignition sequences, regulating burner output, monitoring sensor inputs, and managing both heating and hot water delivery in real time. When the PCB develops a fault, the effects ripple through every function the boiler performs: loss of display, ignition failure, inconsistent heating, random lockouts, or persistent error codes that cannot be cleared. The Worcester Greenstar 28i Junior HE PCB (Part No. 87483006500 / formerly 87483006340) is the exact control board required to restore full electronic function to compatible Worcester Greenstar Junior HE, Si, and i System boilers — bringing every connected component back under proper control.

This is a professionally refurbished genuine Worcester Bosch component. Each PCB is carefully inspected at component level, repaired where necessary, and subjected to a full operational test before being confirmed fit for dispatch. You receive a board that meets original manufacturer performance standards — providing the same reliable electronic control as a new unit, at a fraction of the cost. No modifications are needed; it installs directly as a like-for-like replacement.
