The Transformer on Your Weil-McLain Boiler

The transformer steps line voltage down to the low voltage the control board, thermostat, zone valves and gas valve need. A failed transformer leaves the boiler dead or the controls unpowered.

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