The Goodman 0130M00074 is a genuine OEM high pressure cut-off (HPCO) safety switch designed for the DCC3000604BJXXAB air conditioner and other compatible Goodman/Amana packaged and split systems. This automatic-reset switch monitors discharge-line refrigerant pressure and opens the control circuit when pressure climbs to an unsafe level—protecting the compressor from damage caused by condenser airflow restrictions, overcharge, or a failing condenser fan.
This is the genuine Goodman OEM component, factory-calibrated to the exact cut-out and cut-in set points your system was engineered for. Generic substitutes may trip at incorrect pressures, causing nuisance lockouts or—worse—failing to protect the compressor. For a critical safety control like the HPCO, OEM is strongly recommended.
Moderate. Replacement requires recovering or isolating refrigerant at the access fitting, disconnecting the two control wires, and swapping the switch. Best performed by an EPA-certified HVAC technician. Always disconnect power before servicing.
