Bard 9044-219 - Pressure Switch

Bard part 9044-219 is an OEM pressure switch (manufacturer reference 1000744) used in Bard wall-mounted HVAC equipment to prove proper draft or airflow conditions before the unit is allowed to operate. This safety control monitors pressure through its sensing ports and signals the control board when the required pressure is present, helping prevent nuisance lockouts and protecting key components when venting or airflow is restricted. Replace this switch when you have a verified pressure switch fault, intermittent proving, or consistent pressure-related shutdowns, and always confirm hose routing, port cleanliness, and the required setpoint by matching your unit model and the Bard service literature before ordering.
