The Goodman 0130M00074 High Pressure Cut-Off Switch is a genuine OEM refrigerant safety control designed for the Goodman APH1636M41AB heat pump and compatible Goodman/Amana systems. This normally-closed switch monitors discharge-line pressure and opens the compressor control circuit if head pressure climbs to an unsafe level — protecting the compressor from damage caused by a dirty condenser coil, failed condenser fan, overcharge, or blocked airflow.
This OEM Goodman switch is factory-calibrated to the exact cut-out and reset pressures specified for your system. Generic pressure switches may trip at incorrect thresholds, causing nuisance lockouts or — worse — failing to protect the compressor. For a safety-critical control, OEM calibration is strongly recommended.
Moderate to advanced. This part connects to the sealed refrigerant system. Many replacements use a Schrader-style access fitting that allows swap without recovering refrigerant, but if the port is not self-sealing, EPA-certified refrigerant recovery is required. Disconnect power before servicing. We recommend a licensed HVAC technician for this repair.
Confirm your model and refrigerant type before ordering. Backed by our fitment guarantee.
