The Goodman 0130M00075 Low Pressure Switch is a genuine OEM loss-of-charge safety control for the Goodman WGPH4536AMAB packaged air conditioner and compatible models. Installed on the suction (low) side of the refrigerant circuit, it opens the compressor control circuit when suction pressure drops too low — guarding against compressor damage from a refrigerant leak, low charge, or a restricted metering device.

Specifications

Type: Low-side pressure cut-out switch
Function: Auto-reset on pressure recovery (factory-calibrated)
Circuit: Normally closed, opens on low pressure
Connection: 1/4 in. SAE male flare fitting
Terminals: 1/4 in. spade quick-connect
Fits: Goodman WGPH4536AMAB and compatible packaged units

OEM vs. Generic

The OEM 0130M00075 ships with Goodman's specified cut-out and cut-in set points already calibrated. Universal aftermarket switches frequently use different trip points and fittings, which can cause short-cycling or fail to protect the compressor during a slow leak. OEM is the safe choice for this safety device.

Installation Difficulty

Moderate. Power must be disconnected and the switch connects to a low-side refrigerant port plus two low-voltage terminals. Some setups require an EPA-certified technician for refrigerant access. Allow 20–40 minutes.
