The Carrier HK06WC027 Pressure Switch is a factory authorized part designed for precision monitoring in commercial rooftop units and residential HVAC systems. As a critical safety limit switch, this component detects pressure fluctuations across the outdoor compressor or fan housing to prevent evaporator coil damage and ensure operational integrity. Engineered for high-pressure limit applications, it provides a reliable dry contact signal for building controllers or system boards. This OEM pressure switch features a 1/8-inch process connection and is calibrated for specific pilot flow rates between 2.7 and 6.0 amps. Unlike universal alternatives, the HK06WC027 is a drop-in replacement that maintains the original equipment’s agency listings and safety standards. For accurate sensing, the switch must be installed vertically according to manufacturer specifications. Utilizing a robust SPST configuration, it offers a dependable solution for fan status monitoring and air conditioner protection in demanding environments.

Is the Carrier HK06WC027 compatible with other HVAC brands?
While often found in Carrier and Bryant units, it is used in various single package rooftop units. Check your service manual for the specific HK06WC027 part number to ensure a proper match.

Can I adjust the set point on this pressure switch?
This switch can be adjusted for specific job site conditions. Turning the adjustment screw clockwise will increase the set point to accurately reflect fan or filter status.

What happens if the pressure switch fails?
A failed switch typically prevents the system compressor or fans from engaging, often triggering a fault code or indicator light to protect the equipment from operating under unsafe pressure levels.
