Carrier HK02SB031 Low Pressure Switch

Description

The Carrier HK02SB031 is a genuine OEM low pressure switch designed to protect Carrier heating and cooling systems from operating under unsafe low-pressure refrigerant conditions. When system pressure drops below the designed threshold, this switch interrupts the circuit to prevent compressor damage, refrigerant loss complications, and costly system failures.

Key Features

• Genuine Carrier OEM replacement part for reliable, like-for-like performance
• Monitors refrigerant circuit pressure and shuts down the system when low pressure is detected
• Helps prevent compressor damage caused by low refrigerant charge or loss of charge conditions
• Direct drop-in replacement — no modifications required for compatible Carrier equipment
• Engineered to Carrier’s quality and performance standards for long service life

Application

• Designed for use in compatible Carrier residential and light commercial HVAC systems
• Commonly used in split-system air conditioners and heat pumps
• Refer to your equipment’s service manual or parts list to confirm compatibility before installation

Why Use a Genuine OEM Pressure Switch?

Using a genuine Carrier OEM low pressure switch ensures the replacement component meets the exact electrical and pressure specifications of your original equipment. Aftermarket substitutes may not provide the precise cut-in and cut-out pressure settings required for proper system protection, potentially voiding equipment warranties or causing premature compressor failure. The HK02SB031 delivers the peace of mind that comes with factory-matched components.
