The Goodman 0130M00087 Low Pressure Switch is a genuine OEM safety control for the Goodman DCC300 series 25-ton commercial package air conditioner (model DCC300XXX7BXXXAB). Installed on the suction (low) side of the refrigerant circuit, it disables the compressor when suction pressure drops below the safe threshold — protecting against loss-of-charge, evaporator freeze-up, or a restricted metering device.
The OEM 0130M00087 is set to the precise low-pressure cut-out point for the DCC300 refrigerant circuit, preventing the compressor from running on a depleted charge. Generic substitutes often carry generic setpoints that trip too early (nuisance lockouts) or too late (compressor damage). Factory calibration matters for this protective device.
Moderate — Requires access to the low-side service port, low-voltage wiring changes, and operational verification. Recommended for a qualified HVAC technician. Disconnect power and observe EPA refrigerant-handling rules before service.
