The Goodman 0130M00075 is a factory-original low pressure switch engineered for the APH1624M41AA heat pump and compatible Goodman/Amana units. Installed on the suction (low) side of the refrigerant circuit, this switch opens the control circuit when suction pressure drops too low — a classic sign of a refrigerant leak, loss of charge, or restricted flow. By de-energizing the compressor before it runs dry, it prevents overheating and expensive compressor failure.
The OEM 0130M00075 ships with Goodman's exact low-side setpoints and the correct fitting and terminals. Generic replacements risk mismatched trip pressures that either strand the compressor unprotected or cause repeated nuisance lockouts. OEM removes the guesswork.
Rating: Moderate (3/5). As a refrigerant-line-mounted component, installation may require refrigerant recovery and re-evacuation depending on port design. Always disconnect power first and follow EPA-compliant refrigerant handling. Professional installation is recommended for anyone without HVAC certification.
