The Goodman 0130M00075 Low Pressure Switch is a genuine OEM refrigerant safety control for Goodman WGPH4549AMAB packaged units. It monitors low-side suction pressure and opens the control circuit to stop the compressor when pressure drops too low — protecting against loss-of-charge, a frozen coil, or restricted refrigerant flow. When it fails, the compressor may refuse to start or may run unprotected during a charge loss.

Specifications

OEM part number: 0130M00075
Type: low pressure (loss-of-charge) switch
Function: opens control circuit on low suction pressure
Fits: Goodman WGPH4549AMAB package unit
Connection: factory spade terminals / refrigerant fitting
Action: auto reset per OEM spec

OEM vs. Generic

The OEM switch carries Goodman's exact cut-out and cut-in pressure setpoints. Aftermarket switches with mismatched setpoints can leave the compressor unprotected or cause repeated nuisance trips. For a low-cost safety component that guards an expensive compressor, the genuine OEM part is the smart choice.

Install Difficulty

Easy to moderate — port-mounted versions typically thread onto a Schrader fitting with two spade wires and no refrigerant recovery; brazed-in versions need an EPA-certified tech. Plan 15–35 minutes. Always disconnect power before servicing and confirm the wiring matches the unit diagram.
