Boiler Wiring Harness Replacement in Greater Vancouver
Connects the boiler's electrical components. Supplied and professionally installed by licensed gas fitters — never sold for DIY.
What the Wiring Harness Does
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.
It distributes power and signals between the control board and every component, so a single corroded pin can mimic a failure in an expensive part.
We supply and fit the wiring harness as part of a complete boiler repair or new installation, and inspect it during annual maintenance for homes across Greater Vancouver.
