Carrier HK02ZA418 Pressure Switch
The Carrier HK02ZA418 Pressure Switch is a mission-critical safety component engineered for precise refrigerant pressure monitoring in high-performance HVAC systems. This factory authorized part is calibrated with an open set point of 448 PSI and a close set point of 327 PSI, ensuring robust system protection against over-pressure conditions. Built to OEM specifications, the HK02ZA418 prevents compressor damage and ensures the longevity of residential and commercial condensing units. Its compact design and high-grade industrial materials allow for seamless HVAC part replacement in Carrier, Bryant, and Payne equipment. For technicians diagnosing cycling issues or pressure faults, this 448/327# pressure switch provides the reliable electrical triggering required to maintain optimal refrigerant cycle integrity. By maintaining these strict operational thresholds, the switch acts as a primary safeguard, protecting the system from efficiency loss and catastrophic hardware failure during extreme thermal loads.
Key Benefits:- Precise Pressure Control: Delivers accurate 448 PSI cut-out and 327 PSI cut-in points to protect the refrigerant circuit.
- OEM Performance: A direct Carrier genuine part that ensures exact fitment and electrical compatibility without modifications.
- Enhanced System Reliability: Defends the compressor against high-head pressure spikes, reducing emergency service calls.
- Durable Construction: Engineered with premium materials to withstand frequent cycling in demanding environments.
- Is this switch compatible with R-410A systems? Yes, the 448/327# pressure ratings are specifically designed to handle the higher operating pressures of R-410A refrigerant.
- Can I use this on Bryant or Payne equipment? Absolutely. As a factory authorized part, it is the standard replacement for compatible Bryant and Payne models.
- What causes this switch to trip frequently? Frequent tripping usually indicates a dirty condenser coil, a failing outdoor fan motor, or a restriction in the refrigerant line.
