Application
This pressure switch is a critical safety component in gas furnaces. It senses the negative pressure (draft) created by the inducer blower and signals the control board that adequate airflow is present before the ignition sequence begins. If the required pressure level is not achieved, the switch remains open and prevents ignition, protecting the system from unsafe operation. Always verify compatibility with your specific Nordyne model before installation.
