This high-performance air pressure switch is an essential safety component for residential and commercial HVAC systems. Functioning as an air-proving switch, it accurately monitors the draft inducer motor's pressure to ensure that combustion gases are being safely vented before allowing the furnace to ignite. Rated at 22/45 PSI, this switch is engineered to detect precise pressure changes, preventing the heating system from operating under unsafe conditions such as blocked vents or inducer motor failure. Replacing a faulty pressure switch can resolve common furnace ignition issues and intermittent cycling, ensuring reliable heating and efficient operation. Durable and responsive, this part is designed to meet the rigorous demands of modern high-efficiency heating equipment.
