Description
The Lennox 80W54 Single-Stage Pressure Switch is a safety control system designed for use in HVAC systems to monitor air pressure within the combustion or venting system. It detects proper draft conditions and confirms that airflow is within the required range before allowing the heating cycle to proceed. Commonly used in gas furnaces, this switch interacts with the inducer motor and control board to check better operation. If pressure levels fall outside acceptable limits, it interrupts the circuit to prevent unsafe conditions. Within the system, it supports controlled ignition and protects components from improper airflow or vent blockage.
