Description
The Lennox 79J08 is an OEM suction pressure switch designed to monitor and protect the low-pressure side of HVAC and refrigeration systems. Set at 25 PSI, this switch safeguards the compressor by detecting abnormal suction pressure conditions — shutting down the system before damage can occur from low refrigerant charge, restricted airflow, or other fault conditions.
Key Features
- OEM Lennox replacement part for reliable, factory-spec performance
- 25 PSI suction-side pressure setpoint for low-pressure circuit protection
- Monitors suction line pressure to prevent compressor damage
- Designed for use in residential and light commercial HVAC systems
- Direct OEM replacement ensures proper fit and function
- Helps maintain system efficiency and equipment longevity
Application
The 79J08 suction pressure switch is engineered as a direct OEM replacement for compatible Lennox heating and cooling equipment. It is installed on the suction (low-pressure) side of the refrigerant circuit and activates to cut power to the compressor when pressure drops below the rated threshold, preventing compressor burnout and refrigerant-related system failures.
