The Goodman 0130M00087 Low Pressure Switch is a genuine OEM safety control built for DCC300 series commercial packaged air conditioners such as the DCC300XXX4VXXYAA. It senses suction-line pressure and opens the control circuit when refrigerant pressure drops too low, providing loss-of-charge and freeze protection that prevents the compressor from running under starved, damaging conditions.
The genuine Goodman OEM switch arrives pre-set to the correct low-side cut-out and cut-in pressures for your unit. Generic substitutes frequently use different setpoints or fittings, leading to short-cycling or unprotected operation. Choosing OEM ensures reliable compressor protection and a clean fit.
Moderate — Wiring is straightforward, but mechanical connection to the refrigerant circuit may require recovery and EPA-certified handling. Always cut power before service. Professional installation recommended.
