Navien Flame Sensor Replacement in Greater Vancouver
Genuine Navien flame sensor, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Flame Sensor on Your Navien Boiler
The flame sensor (flame-rectification probe) confirms a flame is actually burning. If it cannot detect flame, the control shuts the gas off within seconds. A dirty or failed sensor causes the boiler to light then drop out repeatedly.
On Navien systems — including models such as NCB-240E, NCB-210E, NHB-150 — a failing flame sensor often shows up as e003 ignition failure or related symptoms. We diagnose it precisely and install the correct genuine Navien part.
