The Goodman 0130M00075 Low Pressure Switch is a genuine OEM safety control for APH1536M41 series heat pumps. It monitors suction-side refrigerant pressure and opens the control circuit on a loss-of-charge or low-pressure condition, preventing the compressor from running dry and burning out due to a refrigerant leak or blocked metering device.
This authentic Goodman OEM switch carries the precise low-pressure trip and reset points matched to your system. Generic replacements with off-spec setpoints can cause nuisance trips in cold weather or fail to protect the compressor during a slow leak. OEM ensures correct calibration and a true bolt-in fit.
Moderate (3/5). Depending on the port style, refrigerant recovery may be required — best handled by an EPA-certified technician. Always disconnect power and follow safe refrigerant practices.
