Trane COM11528 COMPRESSOR; SCROLL, SDA042B1CPZ, R410A, 208/230-60-1 4TTR4048L000AA

The Trane COM11528 is a high-efficiency Alliance Scroll compressor engineered to serve as the high-pressure "heart" of your 3.5-ton air conditioning or heat pump system. This Genuine OEM Alliance compressor functions as the primary refrigerant pump, utilizing a precision scroll orbiting motion to compress R-410A refrigerant with minimal friction. Specifically designed for Trane and American Standard residential units, it provides the exact electrical profile and mechanical lift required to maintain system SEER2 ratings. By choosing a genuine COM11528, you ensure the internal motor windings and centrifugal oil pump are perfectly matched to your system’s original factory specifications, eliminating the performance lag often found in generic replacements.

Key Features:


• High-Efficiency Scroll Technology: Features an Alliance SBA040B1CPZ scroll set that provides continuous compression for smoother airflow and significantly reduced mechanical vibration.
• Genuine OEM Electrical Profile: Engineered for a 20.6 RLA (Rated Load Amps), ensuring your existing contactor, capacitors, and wiring stay within safe operational parameters without nuisance tripping.
• Ultra-Quiet Internal Valving: Includes internal pressure relief and discharge muffling to fix the "clunking" noise issues common in aging or failing reciprocating-to-scroll conversions.
• Direct-Fit Brazed Connections: Features factory-sized 7/8" suction and 1/2" discharge stubs for a seamless "drop-in" fit, reducing the need for field copper adaptations or excessive brazing heat.
• Heavy-Duty Internal Protection: Equipped with an internal line break motor protector that monitors both temperature and current to prevent burnout during low-refrigerant or high-head pressure events.

🛠️ HVAC Depot Pro Tip: The "Triple Evacuation" Rule


When installing the COM11528, always perform a triple evacuation down to 500 microns to remove all non-condensables and moisture. Because scroll compressors use POE oil, which is highly hygroscopic (moisture-absorbing), failing to pull a proper vacuum can lead to acid formation and premature motor winding failure. Never reuse the old filter drier—install the included liquid line drier immediately before the final vacuum pull to ensure a long-lasting repair.
