The Air Pressure Switch on Your Giant 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 Giant systems — including models such as Cascade, Super Cascade, Expert — a failing air pressure switch often shows up as no hot water or related symptoms. We diagnose it precisely and install the correct genuine Giant part.
