Carrier 340481-797 Variable Frequency Drive (VFD) Kit 3-Ton OEM HVAC Replacement

The Carrier 340481-797 is a genuine OEM Variable Frequency Drive (VFD) Kit designed for 3-ton Carrier inverter-driven heating and cooling systems. This replacement VFD kit manages compressor motor speed by converting and regulating electrical power to deliver variable-frequency output, enabling precise capacity control across a range of operating conditions.

Key Features:

• Variable-speed compressor control — adjusts output frequency and voltage to match the system's heating or cooling demand, improving comfort and efficiency
• 3-ton (3T) capacity rating — engineered specifically for compatible 3-ton Carrier inverter-driven condensing and heat pump units
• OEM replacement part — direct factory-matched replacement that maintains original system performance, reliability, and communication with system controls
• Reduces starting current inrush — controls voltage and frequency ramp-up to protect the compressor motor during start cycles
• Supports stable, efficient operation — precise electronic control enables accurate capacity adjustment and reliable coordination between system components
• Genuine Carrier part — manufactured to OEM specifications for long-lasting durability and drop-in compatibility with supported units

This VFD kit is the correct replacement when a system exhibits erratic compressor speed behavior, reduced efficiency, intermittent shutdowns, or an inability to maintain consistent output. Always verify compatibility with the specific unit model before installation. Installation should be performed by a qualified HVAC technician.
