This Goodman -0.60" WC Pressure Switch is an essential safety component for residential gas furnaces and heating systems. Functioning as an air proving switch, it monitors the vacuum pressure created by the draft inducer motor to ensure combustion gases are being properly vented through the exhaust flue. If the system fails to reach the required -0.60 inch water column pressure, the switch prevents the ignition cycle from starting, protecting the unit from mechanical failure and ensuring safe operation. Engineered for high-precision sensing and durability, this vacuum switch is a critical replacement part for HVAC technicians and homeowners looking to restore reliable furnace performance during the heating season.
