Common Questions and Answers
What role does the Lochinvar 100208378 Pressure Switch play in supporting system operation?
The pressure switch monitors air or vent pressure conditions and allows the heating and cooling unit to operate only when proper draft or airflow is present. Its 4.1" WC rating is important because it is built to respond at a specific pressure threshold, supporting safe, consistent performance within the HVAC system.
What symptoms could indicate that the Lochinvar 100208378 Pressure Switch may be wearing out?
The pressure switch may be wearing out if the heating and cooling equipment experiences intermittent startup, unexpected shutdowns or failure to prove proper airflow or draft conditions. Physical signs can include cracked housing, loose terminals or corrosion and environmental signs may include moisture exposure, dirt buildup or residue that could affect switching accuracy.
