## Description

SPECIFICATIONS  The capacitor is 2" in diameter by 4.5" in height and will run from -25 C. to +70 C. It is safety rated at 10,000 AFC.   Fixes the following symptoms:  As the capacitor gets older, the motor may get louder and seem to run slower. If replaced before they get weaker, it's possible to lengthen the life of the motor. Eventually, the capacitor will get too weak to start the motor and if the motor can't start, it can short out. Timely replacement of the capacitor is essential to Air Conditioning Maintenance.   Safety tips for replacement:  When replacing a capacitor, always be sure to turn off the power to the air conditioning unit and place a screwdriver between the terminals of the capacitor to release any stored charge. Our Capacitors are designed to be the correct fit, but it's best to measure the height and width of the capacitor to double check that the replacement unit matches the original.  Count on our 50 MFD Run Capacitor for an unrivaled mix of durability, convenient functionality, and great value for money. Click ‘Add to Cart’ now!

## Features

- ✅ PART NUMBER: PART NUMBER: 50 uf or 50 MFD microfarad Run Round Capacitor. Replaces BOTH 370 VAC & 440 VAC capacitors.
- ✅ FUNCTION: This part works hand in hand with Electric Motors that power the compressors and condensers that make air conditioning work. For this purpose, the Capacitor works the same way as a battery. It stores and releases a large charge very quickly. This released charge gives the motor the spin it needs to start and run correctly.
- ✅ EASY TO INSTALL: 50 MFD Volts which means it will work at 370 or 440 VAC. A dual run capacitor, such as this 40/5, combines two capacitors into one unit. It will power a compressor motor and a fan motor, and has three terminals on the top. They are labeled "Herm" for the compressor motor, "Fan" for the fan, and "C" for the common line.
- ✅ PREMIUM QUALITY: Capacitor is 2" in diameter by 4 1/2" in height so please check this measurement carefully before purchasing. It is designed to last about 60,000 hours. It is also made from durable high quality material and well-tested by the manufacturer.
- ✅ MONEY-BACK GUARANTEE: For any reason you're not completely satisfied, you can ask for a replacement or FULL refund, no questions asked.
