Where would you find the low-pressure cutout switch?

The low-pressure cutout switch is typically located on the suction side of the compressor. This positioning is important because the switch is designed to monitor and respond to the pressure of the refrigerant coming into the compressor. The primary function of the low-pressure cutout switch is to protect the compressor from operating under excessively low pressures, which can lead to insufficient lubrication and potentially cause damage. By being situated on the suction side, it can accurately gauge the refrigerant's pressure and trigger the compressor to shut off if the pressure falls below a certain threshold, ensuring the system operates safely and efficiently.

In contrast, while the metering device, discharge side of the compressor, and the evaporator are all integral components of the refrigeration system, they do not serve the same purpose as the low-pressure cutout switch. The metering device regulates the flow of refrigerant into the evaporator, the discharge side handles the high-pressure refrigerant exiting the compressor, and the evaporator facilitates the heat absorption process. None of these locations would provide the necessary pressure monitoring for the low-pressure cutout function.
