The Goodman 0130M00074 High Pressure Cut-Off Switch is a genuine OEM safety control engineered for CPC180XXX3BXXXAA air conditioning condensing units and compatible Goodman/Amana R-410A systems. This switch monitors discharge-side refrigerant pressure and automatically opens the control circuit when pressure climbs to unsafe levels — protecting the compressor from damage caused by a dirty condenser coil, blocked airflow, overcharge, or a failed condenser fan motor.
This is the genuine OEM Goodman switch with factory-calibrated trip points and a sealed pressure diaphragm rated for the unit's design pressures. Generic aftermarket switches are available at lower cost but trip tolerances can drift, leading to nuisance trips or, worse, failure to protect the compressor. For a safety-critical control, OEM is the recommended choice.
Intermediate. Requires recovering or isolating refrigerant if brazed-in, EPA 608 certification, and proper leak-check after service. Plug-in/Schrader-port versions are easier. Always disconnect power before servicing. Professional installation recommended.
