The Goodman 0130M00075 is a genuine OEM low pressure switch built for the WGPH4543AMAB packaged unit and compatible Goodman/Amana equipment. This normally-closed control monitors suction-side pressure and opens to stop the compressor when pressure drops too low — typically from a refrigerant leak, loss of charge, or restricted metering device. It prevents the compressor from running under starved, damaging conditions.
Like all pressure controls, the trip setpoints are critical. This OEM switch arrives calibrated to Goodman's factory cut-out/cut-in values for the WGPH platform, so it protects without nuisance-tripping on cold-weather low-ambient operation. Aftermarket switches with generic setpoints risk either failing to protect the compressor or locking the system out unnecessarily.
Easy to Moderate — a technician task since it interfaces with the sealed refrigerant system. Recover or isolate charge as needed, replace the switch with a fresh gasket or seal, then evacuate and recharge. Diagnose and repair the underlying low-charge cause before resetting, otherwise the new switch will simply trip again.
