The Goodman 0130M00075 is a genuine OEM low-pressure refrigerant safety switch engineered for the APH1549M41CA Amana/Goodman package heat pump. This control continuously monitors suction-side refrigerant pressure and interrupts the compressor circuit if pressure drops below a safe threshold — protecting the compressor against a loss of charge, restricted metering, or evaporator icing. Installing the correct factory-spec switch keeps the system's safety logic intact and prevents nuisance lockouts.
The OEM 0130M00075 is calibrated to Goodman's exact cut-in and cut-out pressure setpoints, guaranteeing correct compressor protection and preserving warranty coverage. Aftermarket universal switches may use approximate setpoints or non-matching fittings, risking short-cycling or improper trip pressures. For a safety component, we recommend the genuine OEM part.
Moderate. Requires refrigerant-side service — recover or isolate the system, replace the switch, and verify no leaks. Best performed by an EPA-certified HVAC technician. Time: 30–45 minutes.
