Ensure your heating system operates safely and efficiently with this premium air pressure switch. Designed as a critical safety component for residential gas furnaces, this air proving switch monitors the negative pressure generated by the draft inducer motor. It acts as a fail-safe, ensuring that the exhaust fan is venting combustion gases properly before allowing the ignition process to begin. If your furnace is failing to ignite or shutting down shortly after startup, a faulty pressure switch is a common culprit.
