The Nordyne Single Port Pressure Switch is an essential safety component for residential HVAC systems and gas-fired furnaces. This air proving switch is designed to monitor the pressure differential created by the draft inducer motor, ensuring that combustion gases are being properly vented before allowing the ignition sequence to begin. If the system detects an airflow obstruction or mechanical failure, this switch acts as a critical fail-safe to prevent hazardous operation. Featuring a precise -0.70" WC set point, this high-quality vacuum switch is ideal for restoring reliable heating performance in units experiencing startup failures or airflow-related error codes. Its durable construction and single-port configuration ensure a secure connection and long-lasting service life in demanding environments.
