Description
The AAON P59910 is a genuine OEM low pressure switch engineered for use in AAON commercial HVAC systems running R-22 refrigerant. It continuously monitors suction-side refrigerant pressure and opens the control circuit when pressure drops to approximately 30 PSI — safeguarding the compressor against damage caused by low refrigerant charge, restricted airflow, or other fault conditions. By shutting the system down before damage can occur, this safety control helps extend compressor life, reduce costly repairs, and maintain reliable operation in demanding commercial heating and cooling environments.
