The Air Pressure Switch on Your Bosch 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 Bosch systems — including models such as Greenstar, Greentherm, Tronic — a failing air pressure switch often shows up as ea no flame or related symptoms. We diagnose it precisely and install the correct genuine Bosch part.
