Carrier P031-4151 Compressor
The Carrier P031-4151 Compressor is a high-performance HVACR replacement part engineered for demanding service in Carrier 48TJD008-510 and 50TJS008-501 rooftop units. Operating on a 200-230V 3-phase power supply, this heavy-duty unit delivers a nominal capacity of 41,500 BTU, making it a reliable solution for light commercial air conditioning and heat pump applications. As a direct R22 refrigeration compressor, it facilitates seamless repairs in legacy systems without requiring a full refrigerant retrofit, though proper oil management is critical during installation. Featuring a solid-state crankcase heater to prevent liquid migration and an expanded capacity range, this model is a common replacement for older AH series compressors. For technicians, the 13.3-amp draw and 7/8" x 1/2" inlet/outlet sizes ensure compatibility with existing line sets. This OEM-grade Carrier compressor is built for longevity in high-cycle environments where maintaining system equilibrium is paramount.
Key Benefits for Commercial HVAC Systems- Broad Compatibility: Direct replacement for various legacy AH models used in Carrier and Bryant RTUs.
- Enhanced Reliability: Integrated solid-state crankcase heater protects against cold-start slugging.
- Optimized Performance: Engineered for 3-phase stability, reducing thermal stress on electrical components.
- R22 Ready: Designed specifically for mineral oil environments and R22 system pressures.
Is the P031-4151 compatible with R407C dry-charge units?
While originally designed for R22, this compressor can support R407C if the mineral oil is thoroughly flushed and replaced with POE oil, following standard industry retrofitting guidelines.
Does this compressor include the mounting hardware?
This SKU typically includes the internal compressor assembly; technicians should reuse existing mounting grommets or source new 1-3/8" bolt pattern kits if the old ones have degraded.
What is the primary cause of failure for 3-phase compressors of this size?
Phase imbalance and contactor pitting are the leading causes. Always verify voltage consistency across all three legs and replace the motor contactor when installing a new P031-4151.
