The genuine OEM Goodman 0130M00074 High Pressure Cut-Off Switch is a safety control designed for Goodman DCC300-series packaged air conditioners. It continuously monitors refrigerant discharge pressure and opens the compressor control circuit if pressure climbs into an unsafe range — protecting the compressor, coil, and refrigerant lines from damage caused by a dirty condenser, failing fan, or overcharge.
This is the genuine Goodman OEM part, factory-calibrated to the exact trip and reset pressures specified for your unit. Universal aftermarket switches often trip at the wrong pressure or fail to reset correctly, risking nuisance lockouts or unprotected operation. For a safety control, OEM calibration matters.
Easy – Intermediate. Replacement is a direct swap with basic tools, but it requires disconnecting power and working near the refrigerant circuit. If your switch is on a sealed Schrader port, no recovery is needed; if it is brazed in-line, leave it to a licensed HVAC technician.
