Carrier HK02ZA224 Pressure Switch
The Carrier HK02ZA224 Pressure Switch is a critical safety component designed for high-pressure monitoring in HVACR systems. This genuine OEM Carrier replacement part is calibrated with precise 362/321# set points to ensure the compressor shuts down if discharge pressures exceed safe operating limits, preventing catastrophic equipment failure. Engineered for durability in demanding environments, this manual reset pressure switch features a SPST configuration. It is compatible with a wide range of Carrier, Bryant, and Payne condensing units and heat pumps. When diagnosing a locked out HVAC system, verifying the continuity of the high-pressure cutout is a standard protocol. Replacing a fouled or sticking switch with this factory-spec Carrier HK02ZA224 ensures the system operates within its design envelope, maintaining reliability for your clients and reducing callbacks. Professional installation is required to ensure proper thread sealing and electrical terminal security.
Key Benefits- Precise Pressure Calibration: Factory set at 362 PSIG cutout and 321 PSIG reset for accurate system protection.
- Direct OEM Replacement: Ensures exact fit and function for Carrier Bryant and Payne equipment, maintaining original engineering standards.
- Enhanced System Safety: Protects the compressor and refrigerant lines from over-pressurization during high-load conditions.
- Robust Construction: Built to withstand commercial and residential vibration and thermal cycling.
What are the trip points for the HK02ZA224?
This switch is rated for a cutout pressure of 362 PSI and a reset pressure of 321 PSI.
Is this a manual or automatic reset switch?
This specific model functions as a high-limit safety cut-out that typically requires a manual reset or system power cycle depending on the control board logic.
How do I confirm if this switch is faulty?
Using a multimeter, technicians should check for continuity across the terminals. If the system pressure is below 321 PSI and the circuit remains open, the switch has likely failed or reached its end of life.
