The Wiring Harness on Your Lochinvar 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 Lochinvar systems — including models such as Knight, Knight WH, Noble — a failing wiring harness often shows up as ignition lockout or related symptoms. We diagnose it precisely and install the correct genuine Lochinvar part.
