Quick answer
The control board (PCB) is the boiler's electronic brain, managing ignition, sensors, the pump and safety controls. If your boiler control board is failing in Mission, a licensed technician must diagnose and replace it — this is not a DIY job. This involves a safety-critical part. If your boiler keeps faulting, turn it off and book a licensed repair; if you smell gas, leave and call FortisBC at 1-800-663-9911.

Important safety note
PCB faults are diagnosed by a technician. We give honest repair-vs-replace advice, since on an older boiler a new unit can be better value. Please don't attempt to repair or replace boiler parts yourself — book a licensed technician.
Repair or replace?
Often the control board can simply be replaced. On an older boiler, if multiple parts are failing or the repair cost is high, a new high-efficiency boiler may be the better long-term value — and may qualify for BC rebates and financing. We give you honest options for your Mission home.

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.
