Description

Carrier HK06NB010 Pressure Switch Overview

The Carrier HK06NB010 is an OEM replacement pressure switch engineered for reliable furnace and air handler protection. Designed to monitor negative pressure levels within the system, this switch ensures safe and efficient operation by verifying that proper draft conditions are present before allowing ignition to proceed. It is a direct factory replacement for compatible Carrier heating equipment.

Key Features

• OEM Carrier replacement pressure switch for compatible furnaces and air handlers
• Set point: 1.18″ water column (w.c.) for precise pressure monitoring
• SPST (Single-Pole, Single-Throw) switching action for straightforward open/close circuit control
• 1/4″ barb port connection for easy hose attachment and secure fit
• Helps protect against improper draft, blocked flue, or inducer motor failure
• Designed for direct drop-in replacement to minimize downtime

Application

This pressure switch is commonly used in Carrier gas furnaces as a safety control device. It senses the negative pressure (suction) created by the draft inducer motor. If the required pressure differential is not met — indicating a potential venting or inducer issue — the switch remains open, preventing the ignition sequence from continuing and protecting both the equipment and occupants.
