Amana-Goodman 0130R00000S Low Pressure Switch 50/22 PSI

The Amana-Goodman 0130R00000S Low Pressure Switch safety/control element for an HVAC system like an air conditioner or heat pump meant to prevent the system from ever running under extremely low levels of refrigerant pressure. It works through sensing the pressure in the refrigerant system and stopping circulation of refrigerant if the pressure reaches or goes below a fixed limit normally of around 50 PSI. This is because low fuel flow rated can harm the compressor as several other inner components of favorable climatic systems. The switch is usually fitted in the suction line of the refrigerant system and is quite readily replaceable during servicing.
