The genuine Goodman 0130M00075 Low Pressure Switch is an OEM refrigerant safety control engineered as direct-fit replacement for the WPH4324AHAB packaged heat pump and compatible Goodman/Amana systems. This normally-closed switch monitors suction-line pressure and opens the control circuit when refrigerant pressure drops below its trip point, protecting the compressor from damaging low-charge or loss-of-charge conditions.

Function: Loss-of-charge / low-charge compressor protection
Contact configuration: Auto-reset, normally closed
Connection: 1/4" SAE / spade terminals
Fits: Goodman WPH4324AHAB and compatible models
Brand: Goodman (OEM)

OEM vs. Generic

The OEM 0130M00075 is calibrated to Goodman's exact cut-in/cut-out pressure spec, guaranteeing correct compressor protection and preserving your equipment warranty. Aftermarket generic switches are lower cost but pressure calibration can vary, risking nuisance trips or inadequate protection. For a safety-critical control, OEM is the recommended choice.

Installation Difficulty

Moderate — Requires disconnecting power, discharging system safety, and connecting to the refrigerant port. Some switches thread onto a Schrader-style fitting without recovering refrigerant; others require system pumpdown. Professional HVAC installation recommended.
