The Goodman 0130M00074 High Pressure Cut-Off Switch is a genuine OEM safety control for the Goodman/Amana APH1530M41BA packaged heat pump. Wired into the compressor control circuit, this switch monitors refrigerant discharge pressure and opens the circuit to shut down the compressor if pressure climbs into an unsafe range — protecting the compressor and refrigerant loop from damage caused by a dirty condenser coil, overcharge, or airflow restriction.
The factory switch is calibrated to Goodman's exact trip and reset pressure setpoints for this equipment. A generic switch with different setpoints may nuisance-trip or, worse, fail to protect the compressor. Because this is a safety-critical control, the genuine OEM part is strongly recommended.
Moderate. Replacement involves the sealed refrigerant system, so recovery, evacuation, and recharge may be required depending on the connection type. This work should be performed by an EPA-certified HVAC technician. Always disconnect power and follow proper refrigerant-handling procedures.
This is a genuine OEM Goodman replacement part. Verify your unit's model and serial number before ordering.
