Carrier P032-3721 Compressor

The Carrier P032-3721 is a high-performance reciprocating compressor designed for R-22 refrigerant systems, delivering a nominal cooling capacity of 37,800 BTU. Operating on a 230V single-phase power supply at 60Hz, this hermetic compressor is engineered for reliability in residential and light commercial air conditioning and heat pump applications. It serves as a direct technical equivalent for the S1-H22J38BABCA model and is manufactured by Bristol under the Benchmark series. For field installation, this unit features a 7/8-inch suction inlet and a 1/2-inch discharge size, ensuring compatibility with standard line sets. The P032-3721 is built with internal thermal protection to safeguard against motor overheating and requires a 45/370 or 45/440 MFD run capacitor for optimal starting torque and efficiency. As a veteran technician knows, maintaining OEM specifications is critical for system pressure balance and long-term performance in legacy R22 HVAC systems.

• Precise Compatibility: Direct replacement for Carrier P032-3721 and S1-H22J38BABCA, reducing field modification time.
• Robust Reciprocating Design: Engineered for durability in high-demand environments, maintaining efficient compression cycles.
• Extensive Cross-Reference: Replaces a wide array of legacy part numbers, including P032-3825, JD3960AA, and various 06AL/06RL series compressors.
• Factory Authorized Quality: Matches original equipment performance standards for air conditioners and heat pumps.

Is the Carrier P032-3721 compatible with R-407C?
While this unit is optimized for R-22 refrigerant using 3GS mineral oil, some contractors use it in R-407C retrofits after a full oil flush and replacement with POE oil; however, it is specifically designed for R22 systems.

What are the electrical requirements for installation?
The compressor operates on 208-230V/1Ph/60Hz and has a Locked Rotor Amperage (LRA) of 86. Ensure the existing run capacitor is tested or replaced with a 45 MFD @ 370/440 VAC unit.

Are mounting accessories included with the unit?
Yes, the package typically includes the compressor unit along with essential mounting grommets, bushings, and basic installation instructions to ensure a proper 4-point mount.
