The Goodman 0130M00075 is a genuine OEM low pressure switch for the WGPH4560AMAB packaged air conditioner. It senses refrigerant suction pressure and opens the control circuit when pressure drops too low — a frequent symptom of refrigerant loss, restricted flow, or extreme cold — preventing the compressor from running dry and burning out.
The OEM switch is calibrated to Goodman's factory cut-out and cut-in setpoints for accurate compressor protection. A generic equivalent with matching pressure thresholds and connection type offers a budget option for out-of-warranty repairs. Because this part guards the compressor, the OEM choice is the most reliable.
Moderate (3/5). Depending on the fitting, replacement may involve the sealed refrigerant system and should be handled by an EPA-certified technician. Disconnect power at the breaker, verify the failure with a meter, and confirm operating pressures after installation.
