Description
The Goodman 20197308 is an OEM pressure switch designed for use in Goodman heating and air handling equipment. Color-coded yellow for quick identification during installation and service, this pressure switch is set at a -.10″ W.C. (inches of water column) setpoint, making it a critical safety component in the combustion air proving circuit of compatible furnace systems.
Product Overview
Pressure switches in furnace applications monitor the negative pressure created by the inducer motor to confirm proper venting and combustion airflow before allowing the gas valve to open. If the required pressure differential is not achieved — due to a blocked flue, failed inducer, or cracked pressure switch hose — the switch remains open, preventing unsafe furnace operation. The yellow color coding on this switch helps technicians quickly distinguish it from other pressure switches in multi-switch applications.
