Carrier HK06MC058 Pressure Switch Kit

The Carrier HK06MC058 is a professional-grade Dual Pressure Switch Kit engineered for precision monitoring of refrigerant circuits and combustion air in residential and commercial HVAC systems. This factory-authorized OEM part serves as the direct technical successor and replacement for the HK06WC058, ensuring seamless integration with existing control boards and compressor contactors. Designed for heavy-duty field reliability, the kit features high-performance pressure-sensing switches mounted on a rugged steel bracket. These switches are calibrated to open or close electrical circuits when system pressures deviate from safe operating limits, specifically protecting the unit during low-fire (-0.18" WC) and high-fire (-0.27" WC) stages. Specifically compatible with the Carrier 58CVA series and various ICP furnace models, this dual-switch configuration is critical for preventing compressor failure and ensuring balanced refrigerant flow. By utilizing heavy-duty electrical contacts, the HK06MC058 handles high-current switching with minimal voltage drop, making it the standard solution for contractors performing troubleshooting or preventative maintenance on modern high-efficiency HVAC equipment.

• OEM Precision Compatibility: Purpose-built for Carrier 58CVA155 series and ICP systems to ensure exact set-point accuracy without field modifications.
• Direct HK06WC058 Replacement: Eliminates retrofit issues by utilizing the original mounting footprint and wiring terminal positions for a fast "drop-in" installation.
• Durable Construction: Features a corrosion-resistant steel mounting bracket and high-cycle industrial contacts designed for demanding thermal environments.
• Comprehensive System Protection: Monitors both high- and low-side pressure to prevent system operation under hazardous conditions, extending the service life of the compressor.

Is the HK06MC058 compatible with older furnace models?
Yes, this kit is the official replacement for HK06WC058 and is designed for broad compatibility across Carrier and ICP gas furnaces, specifically those utilizing dual-pressure safety logic.

Does this switch kit include the mounting bracket?
Yes, the HK06MC058 comes pre-mounted on a steel bracket to ensure proper alignment and easy installation during a service call.

How do I verify if my switch is faulty?
Technicians should check for continuity across the contacts while the system is at the appropriate water column pressure. If the switch fails to close at the rated -0.18" or -0.27" WC, a replacement is necessary for safe operation.
