OEM Goodman Low Pressure Switch for APH1624H41AA Heat Pump — 0130M00075

Goodman 0130M00075 Low Pressure Switch

The Goodman 0130M00075 is an OEM low-pressure switch that safeguards the compressor in the APH1624H41AA heat pump by opening the control circuit when refrigerant suction pressure drops too low — typically from a leak, loss of charge, or restricted flow. Running a compressor under low-charge conditions leads to overheating and lubrication loss. A properly functioning low-pressure switch shuts the system down before damage occurs.

OEM vs. Generic

The genuine Goodman OEM switch is factory-calibrated to the precise cut-out and cut-in suction pressures for your model, with the correct fitting and terminal spacing. Generic substitutes can trip early, lock out the system unnecessarily, or fail to protect against a slow leak. The OEM part delivers the exact protection window Goodman engineered.

Installation Difficulty

Moderate (3/5). The switch ties into the low-side refrigerant circuit, so replacement may involve recovering refrigerant and, on some units, brazing. Kill power at the breaker, recover refrigerant per EPA regulations, then replace the switch and reconnect the terminals. EPA 608 certification is required to work with refrigerant — we recommend a licensed technician for this job.
