The Wiring Harness on Your Dunkirk Boiler

The wiring harness ties together the control board, sensors, igniter, valves and pump. Heat-damaged, chafed, or corroded harness connectors cause intermittent faults that are notoriously hard to chase down without proper diagnosis.

On Dunkirk systems — including models such as Q90-200, XEB, PWX — a failing wiring harness often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Dunkirk part.
