Carrier HK02SB022 Low Pressure Switch 117/054 PSI

The Carrier HK02SB022 is a genuine OEM low pressure switch designed for residential and light commercial HVAC refrigeration systems. This critical safety component continuously monitors refrigerant pressure levels and protects the compressor and system from damage caused by low refrigerant conditions.

Key Features:

• Pressure settings: 117 PSI close / 54 PSI open
• Automatically shuts down the system when refrigerant pressure drops below safe operating levels
• Prevents compressor damage from low pressure conditions
• Genuine Carrier OEM replacement part ensures proper fit and reliable performance
• Direct replacement for original factory-installed pressure switches

This low pressure switch is an essential component for maintaining optimal system performance and preventing costly repairs. When refrigerant pressure falls below 54 PSI, the switch opens the circuit to deactivate the system. Once pressure is restored to 117 PSI, the switch closes and allows normal operation to resume. Compatible with Carrier, Bryant, and Payne air conditioning and heat pump systems.
