Glowworm Jaguar 23/28KW PCB – Refurbished | Part No. 0020025305

Boiler shutdowns, ignition failures, repeated resets, or error codes on a Glowworm Jaguar 23 or 28KW boiler are often caused by a failed printed circuit board. The PCB is the central brain of the boiler — it manages ignition sequencing, flame sensing, system monitoring, and safety lockout. The Glowworm Jaguar 23/28KW PCB (Part No. 0020025305) is a professionally refurbished direct replacement, fully tested to restore stable boiler operation across the complete Jaguar range.

This refurbished unit has been cleaned, inspected, and tested by our experienced engineering team before dispatch. All critical functions — including ignition control, flame detection, and safety monitoring — are verified to be operating correctly. Supplied with a full 12-month warranty.
