A. O. Smith Thermocouple Replacement in Greater Vancouver
Genuine A. O. Smith thermocouple, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Thermocouple on Your A. O. Smith Boiler
The thermocouple is a safety probe that senses the pilot flame and holds the pilot gas valve open. When it weakens, the gas valve closes and the pilot goes out — the most common cause of a pilot that will not stay lit.
On A. O. Smith systems — including models such as ProLine, Signature, Voltex — a failing thermocouple often shows up as no hot water or related symptoms. We diagnose it precisely and install the correct genuine A. O. Smith part.
