York S1-5992121 Low-Pressure Switch 50/71 OPCl

The York S1-5992121 Low-Pressure Switch is an essential safety device in HVAC systems. It controls refrigerant pressure and does not allow the system low pressure. This switch operates under pressure range of 50-71 PSI and opens when the system pressure is below the set range. This operation normally shuts off the compressor to avoid damage from low refrigerant charge. When the pressure goes up over the set limit, the switch turns on enabling the system to continue running. The low-pressure switch effectively saves and prolongs the life of the compressor by avoiding the continued functioning of the system at low pressure. It also helps in achieving the system performance and productivity due to the right amounts of refrigerant.
