Heatcraft Refrigeration 28903201 Pressure Switch
The Heatcraft Refrigeration 28903201 Pressure Switch is a high-side safety essential designed to protect commercial refrigeration compressors from catastrophic failure due to excessive head pressure. Built for rigorous field duty, this 425-320# high pressure switch features a fixed 400 psi cutout (opening at 425 psi according to technical benchmarks) and a 320 psi reset. As an authentic OEM Heatcraft replacement part, it ensures direct compatibility with Interlink and Heatcraft condensing units, maintaining the precise calibration required for R-404A and other high-pressure refrigerant systems. This HVAC pressure control is engineered with a robust, compact housing to withstand the vibration and thermal cycling common in industrial condenser sections.
Key Benefits:
- System Protection: Actively prevents compressor overheating and motor burnout by interrupting the control circuit during high pressure cutout events.
- Field Reliability: Features a fixed pressure setting to eliminate tampering or accidental drift, ensuring the system operates within OEM specifications.
- Durable Construction: Heavy-duty electrical contacts and a hardened enclosure provide long-term performance in demanding refrigeration pressure switch applications.
- Direct Fit: Replaces legacy part numbers like HTCR28917501, reducing downtime during emergency service calls.
Common Questions:
- What causes this switch to trip frequently? Frequent trips are often a symptom of a dirty condenser coil, a failing condenser fan motor, or a refrigerant overcharge rather than a switch failure. Always verify system pressures with a manifold gauge before replacing.
- Can this switch be used with R-410A systems? While rated for high pressure, always cross-reference the specific cut-in/cut-out requirements of your equipment. This model is typically calibrated for Heatcraft refrigeration platforms.
- Is this a manual or automatic reset? This specific model (28903201) operates on an automatic reset logic, closing the circuit once the high-side pressure drops back to the 320 psi threshold.
