Description
Carrier HK06NB017 Dual Pressure Switch Overview
The Carrier HK06NB017 is an OEM dual pressure switch engineered for use in Carrier furnaces and air handlers. This single component integrates two pressure-sensing circuits, monitoring both the low-pressure and high-pressure thresholds of the inducer assembly to ensure safe and reliable furnace operation. By verifying proper draft inducer performance before allowing ignition, the dual pressure switch serves as a critical safety device that protects against incomplete combustion and heat exchanger damage.
Key Specifications
- Manufacturer Part Number: HK06NB017
- Brand: Carrier
- Type: Dual Pressure Switch
- Low-Pressure Setpoint: 0.71″ w.c.
- High-Pressure Setpoint: 1.60″ – 1.81″ w.c.
- Direct OEM replacement for compatible Carrier furnace models
How It Works
The dual pressure switch monitors the negative pressure (vacuum) generated by the draft inducer blower. The low-side switch (0.71″ w.c.) confirms that the inducer is operating and producing adequate draft before the ignition sequence begins. The high-side switch (1.60″–1.81″ w.c.) provides an additional safety check to verify proper venting conditions. If either setpoint is not met, the furnace control board will lock out the ignition sequence, preventing unsafe operation.
Features & Benefits
- Dual-circuit design replaces two separate switches in a single unit
- Calibrated setpoints ensure accurate pressure monitoring at 0.71″ w.c. and 1.60″–1.81″ w.c.
- Protects heat exchanger and venting system from draft-related failures
- Direct OEM replacement ensures fit, form, and function compatibility
- Helps maintain furnace efficiency and safety compliance
Application
The HK06NB017 is designed as a direct OEM replacement for compatible Carrier furnace systems. Always verify compatibility with your specific furnace model number before installation. Consult the equipment service manual for proper wiring and pressure tap connection procedures.
