Description
Product Summary
The Supco LCD45+7.5X440R Round Dual Run Capacitor, 45+7.5 MFD, 440V is a professional-grade replacement part from Supco (Sealed Unit Parts Co.), a trusted name in HVAC/R and appliance parts since 1945. Engineered by an ISO manufacturer with over twenty years' experience in OEM capacitor fabrication, Linebacker® capacitors are manufactured by the OEM factory and are 100% in-line production tested to the same rigorous standards.
Dual run capacitors combine the compressor (HERM) and outdoor fan (FAN) run capacitors in a single can with a shared common (C) terminal, which is how most residential condensers and packaged units are built. When either section drifts out of tolerance, the system can hum, run hot, or fail to start. Match both MFD ratings and use an equal or higher voltage rating; 440V units can replace 370V units.

Frequently Asked Questions
Can I replace a 370 VAC capacitor with a 440 VAC capacitor?
Yes you can. A common misconception is that you must have a 370 volt capacitor to replace a 370 volt capacitor. However, the voltage rating on a run capacitor displays the voltage that should not be exceeded.
Why should I replace the run capacitor with the same MFD rating?
A larger or smaller MFD rated capacitor can cause energy consumption to rise and shorten the life of the motor due to overheated motor windings.
