The Air Pressure Switch on Your Weil-McLain Boiler

The air pressure switch proves the combustion fan is moving air and the flue is clear before the control allows ignition. A failed switch or blocked sensing tube is a frequent cause of no-heat lockouts.

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