The Goodman 0130M00075 is a genuine OEM low-pressure switch built for the DCH0480184BHXFAC package unit. This safety control watches refrigerant suction pressure and opens the control circuit when pressure drops too low — protecting the compressor against loss-of-charge, refrigerant leaks, and freeze-up conditions that would otherwise cause slugging or overheating.
OEM vs. Generic: This genuine Goodman switch is calibrated to the precise low-side cut-out and reset pressures your unit requires. Aftermarket substitutes may use different setpoints or thread sizes, causing nuisance trips or leaving the compressor unprotected. For dependable protection, choose OEM.
Install difficulty: Moderate — mounts to a low-side refrigerant port and may require refrigerant recovery unless an access fitting is present. Recommended for an EPA-certified technician. Always disconnect power before servicing.
Fast shipping and backed by our 1-year replacement warranty.
