Product Details

Description

Ensure your high-efficiency furnace operates safely and efficiently with this premium 2-stage air pressure switch. Designed specifically for two-stage heating systems, this air proving switch monitors the pressure differential created by the draft inducer motor to verify proper airflow and venting before allowing ignition. Featuring precise setpoints of 1.00" WC and 0.25" WC, it provides accurate monitoring for both high-fire and low-fire heating cycles. As a critical safety component, this switch prevents the furnace from running if it detects a blocked flue or a failing inducer fan. This durable replacement part is essential for maintaining HVAC system reliability and protecting your home from improper combustion gas venting.
