The 0130M00087 is a genuine OEM low-pressure switch built for Goodman DCC300 series commercial package air conditioners. Wired into the suction (low) side, this control opens the compressor circuit when refrigerant pressure drops too low — protecting the compressor against loss-of-charge, refrigerant leaks, restricted airflow, and freeze-up conditions. Replacing a failed low-pressure switch restores proper safety lockout and prevents costly compressor damage.
Genuine Goodman 0130M00087 switches are set to the factory cut-out and cut-in pressures matched to your system's design. Aftermarket universal switches often differ in set point and reset behavior, leading to short-cycling or inadequate protection. Choose OEM for reliable, spec-accurate operation.
Moderate — Involves the refrigerant circuit and low-voltage wiring; recommended for licensed HVAC technicians. Disconnect power, follow EPA refrigerant-handling rules, and verify charge after installation.
