The 0130M00087 is a genuine OEM low-pressure safety switch for the Goodman GCG300360EBXXXAA package unit and compatible Goodman/Amana systems. It monitors refrigerant suction pressure and opens the control circuit if pressure drops below its cut-out threshold—protecting the compressor from damage caused by low charge, restricted airflow, or a failed metering device. A tripped or faulty low-pressure switch is a frequent cause of intermittent cooling lockouts.
The OEM 0130M00087 arrives pre-calibrated to Goodman's exact cut-in/cut-out set points and thread size. Generic switches may use different pressure settings or fittings, risking nuisance trips or a compromised safety response. Choose OEM for correct protection.
Moderate to Advanced—may require recovering refrigerant and brazing/threading on a sealed-system port. Refrigerant work should be performed only by an EPA-certified technician.
