Daikin-McQuay 300002708 Run Capacitor

For professional contractors servicing Daikin-McQuay equipment, the 300002708 Run Capacitor is a mission-critical OEM replacement part designed for continuous-duty applications. This 12 MFD 370V run capacitor features an oval form factor and an aluminum casing, specifically engineered to maintain the power factor correction and motor efficiency of compatible blower motors and fans. In the field, matching the exact 12 microfarad capacitance is vital; a deviation here can lead to increased winding temperatures and premature motor failure. The 370 VAC rating provides the necessary dielectric strength to handle the peak voltages found in residential and light commercial 240V systems. Built to EIA-456-A industry standards, this non-polarized capacitor utilizes a metallized polypropylene film dielectric to ensure stable performance across its operating temperature range. Whether you are performing emergency HVAC troubleshooting or routine preventative maintenance, using this 12uF oval capacitor ensures the system operates within its original laboratory-tested specifications, preserving the longevity of the expensive compressor or fan motor it supports.

• OEM Compatibility: Exact replacement for Daikin 300002708, ensuring the electrical characteristics match the original equipment design.
• Optimized Performance: Maintains the correct phase angle between voltage and current to keep motors running cool and efficient.
• Physical Fit: The standard oval design allows for seamless installation in tight control boxes and existing mounting brackets.
• Reliable Terminals: Equipped with standard 1/4 inch quick-connect terminals for fast, secure wiring.

• Can I use a 440V capacitor if the 370V is out of stock? Yes, you can always step up in voltage (e.g., using a 440V unit), but you must never install a capacitor with a lower voltage rating than the 370V specified.
• Is 12 MFD the same as 12 uF? Yes, these terms are interchangeable in the HVACR industry; both refer to the capacitance rating of the component.
• How do I know if this capacitor has failed? Look for physical indicators like bulging or leaking, and always verify the MFD reading with a multimeter to ensure it is within the ±5% or ±6% tolerance listed on the shell.
