Weil-McLain Thermocouple Replacement in Greater Vancouver
Genuine Weil-McLain thermocouple, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Thermocouple on Your Weil-McLain 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 Weil-McLain systems — including models such as ECO, ECO Tec, Ultra — a failing thermocouple often shows up as low water cutoff trip or related symptoms. We diagnose it precisely and install the correct genuine Weil-McLain part.
