The Gas Valve on Your Navien Boiler

The gas valve regulates the flow of natural gas or propane to the burner and, on modulating boilers, continuously adjusts it to match demand. A faulty gas valve causes ignition failures, no heat, or unsafe combustion, and is a safety-critical component that must be tested and set by a licensed technician.

On Navien systems — including models such as NCB-240E, NCB-210E, NHB-150 — a failing gas valve often shows up as e003 ignition failure or related symptoms. We diagnose it precisely and install the correct genuine Navien part.
