Description
The Lennox 84M96 Loss of Charge Pressure Switch is an OEM-grade safety component engineered to protect your HVAC system from the damaging effects of refrigerant loss. When refrigerant charge drops below safe operating levels, this pressure switch detects the condition and signals the system to shut down — preventing compressor damage, inefficient operation, and costly repairs.
Key Features
- Genuine Lennox replacement part (SKU: 84M96)
- Loss of charge detection for refrigerant circuit protection
- Designed to safeguard the compressor from low-refrigerant operation
- Direct OEM replacement for compatible Lennox equipment
- Helps maintain system efficiency and extend equipment life
- Reliable switching action for accurate low-pressure fault detection
Why Loss of Charge Protection Matters
Operating an air conditioning or heat pump system with insufficient refrigerant can cause the compressor to overheat, lose lubrication, and fail prematurely. The 84M96 pressure switch acts as a critical safety guard, interrupting system operation the moment a loss-of-charge condition is detected — protecting your investment and keeping service calls to a minimum.
Application
- Compatible with select Lennox air conditioning and heat pump systems
- Ideal for HVAC technicians performing maintenance, repair, or system restoration
- Direct drop-in replacement for worn or failed OEM pressure switches
Installation Notes
Always verify refrigerant charge and inspect for leaks before replacing the pressure switch. Consult the equipment service manual for wiring diagrams and pressure specifications applicable to your specific Lennox model. Replacement should be performed by a qualified HVAC technician.
