Product Details

Description

This premium two-stage air pressure switch is a vital safety component for high-efficiency residential gas furnaces. Engineered to function as an air-proving switch, it monitors the draft inducer motor's performance by sensing vacuum pressure within the combustion chamber. With precise set points of -0.72" WC and -1.47" WC, this dual-stage switch ensures that exhaust gases are being properly vented before the ignition process begins. If the furnace venting system is obstructed or the inducer motor fails to reach the required speed, the switch will interrupt the heating cycle to ensure safe operation. This reliable replacement part is essential for resolving common furnace issues like short-cycling or ignition failure in multi-stage HVAC systems.
