Description
The Amana-Goodman 0130F00643 Pressure Switch is an essential component of the HVAC systems, which is used to regulate system pressure. This pressure switch works on the basis of detecting variations in pressure in the refrigerant line of an HVAC system. if the pressure is above or below such set values the switch moves the electrical contacts to initiate action in the system. For instance, if the pressure rises to an incredible level the switch could turn off the compressor to avoid damage. On the other hand if the pressure reduces so much, the switch might trigger an alarm or other protective mechanisms.
