The Flame Sensor on Your Weil-McLain 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 Weil-McLain systems — including models such as ECO, ECO Tec, Ultra — a failing flame sensor often shows up as low water cutoff trip or related symptoms. We diagnose it precisely and install the correct genuine Weil-McLain part.
