Daikin-McQuay 6023975 OEM Replacement Reactor for Mini-Split Outdoor Units

The Daikin-McQuay 6023975 Reactor is a genuine OEM replacement electrical reactor (choke coil / AC line reactor) designed for use in Daikin mini-split and multi-split outdoor condensing units. This component is installed in the inverter power supply circuit of the outdoor unit and plays a critical role in maintaining stable, efficient system operation.

In inverter-driven HVAC systems, the reactor suppresses harmonic distortion on the power line, reduces electromagnetic interference (EMI), and protects sensitive inverter electronics and compressor components from voltage spikes and power fluctuations. Replacing a faulty reactor restores proper inverter operation and prevents premature failure of the printed circuit board and compressor assembly.

Key Features:

• Genuine Daikin OEM replacement part — ensures correct fit and performance
• Functions as an AC line reactor / choke coil in the inverter power circuit
• Suppresses harmonic distortion and electrical noise for stable inverter operation
• Protects inverter PCB and compressor from power line transients and surges
• Direct OEM replacement — no modification required for installation
• Manufacturer Part Number (MPN): 6023975

This reactor is a listed functional part in multiple Daikin repair parts manuals and is intended for installation by qualified HVAC technicians only. Always refer to the applicable Daikin service and repair parts documentation for your specific model before installation.
