The Goodman 0130M00087 is an OEM low pressure switch designed for the Goodman DCC300XXX4BXXDAB commercial packaged air conditioner. It monitors suction-side refrigerant pressure and breaks the control circuit when pressure drops too low, providing loss-of-charge and freeze protection that shields the compressor from running under low-refrigerant conditions.
This genuine Goodman OEM switch is calibrated to the precise cut-out and cut-in pressures your system requires. Generic substitutes can short-cycle the compressor or fail to protect against a slow refrigerant leak. OEM ensures correct set points and a direct, no-modification fit.
Moderate — The wiring swap is straightforward, but the switch connects to the low-side refrigerant circuit. An EPA-certified technician should perform the replacement to maintain a sealed system and recover refrigerant if needed.
