The Goodman 0130M00074 High Pressure Cut-Off Switch is a genuine OEM refrigerant-circuit safety control designed for Goodman/Amana DCC300-series packaged air conditioners. This automatic-reset switch monitors high-side system pressure and interrupts the compressor circuit when discharge pressure climbs to an unsafe level — protecting the compressor against overheating, condenser airflow loss, overcharge, or a failing metering device.
This is a factory OEM Goodman part, guaranteed to match the original trip and reset pressure settings calibrated for your unit. Generic aftermarket pressure switches may use different cut-out points and brass fittings that can lead to nuisance trips or improper protection. For safety-critical refrigerant controls, OEM is strongly recommended.
Moderate — Refrigerant must be recovered before replacing a switch that threads into the sealed system, or the switch may use a Schrader-style connection. HVAC technician recommended. Always disconnect power before servicing.
