Boiler Flame Sensor Replacement in Greater Vancouver
Licensed, gas-certified diagnosis and replacement of your boiler flame sensor — done safely, no DIY. Serving BC homes since 1999.
Quick answer
The flame sensor confirms the burner has lit. If it can't 'see' the flame, the boiler shuts the gas off as a safety measure. If your boiler flame sensor is failing, 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.
What the flame sensor does
The flame sensor confirms the burner has lit. If it can't 'see' the flame, the boiler shuts the gas off as a safety measure.
Signs your flame sensor may be failing
- Boiler fires then shuts off seconds later
- Short-cycling
- An ignition or flame-fault lockout
Important safety note
A dirty or failed flame sensor is a common, inexpensive fix — cleaned or replaced by a technician during service. It should not be bypassed. Please don't attempt to repair or replace boiler parts yourself — book a licensed technician.
Repair or replace?
Often the flame sensor can simply be replaced. On an older boiler, if several 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 honest options.

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.
