The Goodman 0130M00074 High Pressure Cut-Off Switch is a genuine OEM safety control engineered for APC1560H41BA air conditioning systems. This refrigerant-side switch monitors discharge pressure and opens the control circuit when head pressure climbs to an unsafe level, protecting the compressor from overheating, slugging, and catastrophic failure. When pressure returns to a safe range the switch automatically resets, restoring normal operation without a manual trip.
This is a factory OEM Goodman component built to the exact pressure thresholds Goodman engineering specifies for this platform. Generic aftermarket switches are typically cheaper but may trip at the wrong pressure point, leading to nuisance shutdowns or, worse, failure to protect the compressor. For a critical safety device, we recommend the OEM part to preserve warranty compliance and reliable trip accuracy.
Moderate — requires recovering or isolating refrigerant at the fitting, so this job is best performed by an EPA-certified HVAC technician. Electrical reconnection is straightforward (two spade terminals). Always disconnect power and relieve system pressure before servicing.
