Boiler Flame Keeps Going Out — Repair in Greater Vancouver
Licensed, same-day diagnosis and repair. Genuine OEM parts, professionally installed — never sold for DIY. Trusted since 1985.
Call (604) 359-1081A boiler that lights then drops out seconds later usually has a dirty or failed flame sensor, a poor ground, or a gas/combustion fault — so the control can’t prove flame and shuts off. BoilerPart.ca cleans or replaces the sensor and fixes the cause across Greater Vancouver.
If the burner lights but the boiler shuts down within seconds and locks out, the flame-sensing circuit can’t confirm the flame — a classic flame-sensor symptom.
What you’re noticing
Common causes
- Dirty / oxidised flame sensor
- Cracked sensor insulator

- Gas pressure / combustion fault
