Description
Product Summary
The Supco LCR10X440 Oval Run Capacitor, 10 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.
Run capacitors keep single-phase compressor and fan motors running efficiently by creating the phase shift the motor needs to develop torque. A weak or failed run capacitor is one of the most common reasons an AC or heat pump stops cooling, hums, or runs hot. Replace with the same microfarad (MFD/µF) rating and an equal or higher voltage rating than the original.

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.
