Amana-Goodman 20028405 Pressure Switch 1.25" WC

The Amana-Goodman 20028405 Pressure Switch is a pressure switch with a water column pressure of 1.25 inches used in air conditioners and heat pumps, as well as other HVAC systems. This component regulates and evaluates the flow pattern within the system. It works based on the pressure variation in the airflow passageway. If the pressure drops below a specific level, the switch protects by turning off the compressor for instance. This also prevents compromise of the system’s performance and failure that may be occasioned by poor circulation of air. This allows homeowners to extend the lifespan of HVAC equipment and create a comfortable and safe environment inside their homes.
