Why this needs a licensed technician

Resolving a Outlet Sensor Fault fault almost always involves the gas, combustion, sensor or pressurized side of the appliance.

We diagnose U.S. Boiler (Burnham) boilers, carry common parts, and verify clean combustion before returning your boiler to service.

This is not a DIY repair

Combi boilers are gas-fired appliances regulated under the BC Safety Standards Act. Opening the unit, touching the gas valve, or working on the flue without a valid BC gas-fitter licence is both unsafe and illegal. Diagnosing the fault is helpful — fixing it should always be left to a certified technician.
