Lochinvar & A.O. Smith 100110820 Pressure Switch 321894-708 reducing the total transformer loadThe Lochinvar & A. O. Smith 100110820 Pressure Switch is a critical safety component designed for high efficiency gas fired boiler and water heater systems. This 1. 42" air pressure switch (1. 42 in. WC) functions as a differential pressure switch, ensuring the combustion blower is generating sufficient airflow before allowing the ignition sequence to proceed. As a veteran technician knows, a failing HVAC pressure switch often results in a "no heat"
