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.
