Amana-Goodman 11177113 Dual Pressure Switch

The Amana-Goodman 11177113 Dual Pressure Switch is an essential component in residential and light commercial HVAC systems, primarily air conditioners and heat pumps. It serves as a safety part for measuring high and low pressures of refrigerant in the system. This switch works based on a basic concept In the event that the refrigerant pressure goes high of a pre-set high value, the high pressure switch cuts off the compressor. should the pressure get too low, to the refrigerant, the low side switch opens and cuts off the compressor to prevent system. This dual-pressure protection provides safety and reliability of the HVAC system and protects the equipment.
