The Goodman 0130M00075 is a genuine OEM low pressure switch (loss-of-charge control) designed for the WPH4342AMAB packaged heat pump and matching Goodman/Amana R-410A systems. It watches suction-side pressure and shuts the compressor down when charge drops too low — preventing the compressor from running dry during a refrigerant leak, restricted metering device, or extreme low-ambient conditions.

Specifications

Type: Low pressure cut-out (SPST, opens on fall)
Refrigerant: R-410A rated
Approx. cut-out: 25 PSIG / cut-in: 45 PSIG
Reset: Automatic
Connection: 1/4" flare port with spade terminals
Fits: Goodman & Amana WPH4342AMAB packaged heat pumps

OEM vs. Generic

The OEM 0130M00075 ships with the precise cut-out and cut-in values your unit was engineered around. Aftermarket switches frequently differ on trip points, leading to short-cycling or unprotected operation. Because this part guards the compressor, we recommend the genuine OEM control.

Installation

Difficulty: Moderate — Threads onto a low-side port and wires into the safety string. Refrigerant handling calls for an EPA-certified tech. Straightforward once the system is isolated; always kill power first.

My furnace shows a pressure switch error. What do I replace?

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

Should I use OEM or aftermarket for my Goodman pressure switch?
