Carrier HK02ZA376 Pressure Switch
The Carrier HK02ZA376 Pressure Switch is a high-pressure manual reset safety control designed specifically for Carrier, Bryant, and Payne condensing units and heat pumps. This HVAC high pressure cutout switch is engineered to monitor system pressure and interrupt the control circuit if discharge pressure exceeds the factory setpoint of 386 PSI, preventing potential compressor failure. It resets when pressure drops back to 280 PSI. As a direct replacement for HK02ZA376A, this SPST (Single Pole Single Throw) switch ensures the refrigerant circuit remains within safe operational limits. Contractors often utilize this 386-280# pressure switch when troubleshooting Carrier AC high pressure lockout issues to restore system protection. The robust construction handles high-cycle applications, maintaining calibration throughout its service life. This OEM Carrier replacement part features standard 1/4 inch SAE female flare connections for a secure, leak-free seat on the high-side service port.
- Factory Calibrated Precision: Fixed 386 PSI trip point and 280 PSI reset point ensure accurate refrigerant pressure monitoring.
- OEM Compatibility: Exact replacement for HK02ZA376A, facilitating a seamless fit without modifications to the wiring harness or mounting.
- Manual Reset Safety: Prevents the system from short-cycling after a high-pressure event, requiring technician intervention to diagnose the root cause.
- Durable SPST Contacts: Designed for high-amperage internal pilot duty to ensure reliable HVAC safety circuit interruption.
Common Questions
Is the HK02ZA376 interchangeable with the HK02ZA376A?
Yes, the HK02ZA376 is identical to the HK02ZA376A in form, fit, and technical specifications, making it a direct replacement for those HVAC pressure switch cross-references.
What causes this switch to trip in a Carrier heat pump?
Typically, a trip indicates high head pressure caused by a dirty condenser coil, a failing outdoor fan motor, or a refrigerant overcharge. This high-pressure limit switch protects the compressor from these hazardous conditions.
Can I use this on R-410A systems?
Yes, the 386-280# pressure range is rated for high-pressure refrigerants like R-410A commonly used in modern residential and commercial Carrier HVAC units.
Item is Non Cancelable / Non Returnable
