## Description

SPECIFICATIONS  The capacitor is 2.07" in diameter by 5.44" in height and will run from -40 C. to +85 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 45+7.5 MFD Run Capacitor for an unrivaled mix of durability, convenient functionality, and great value for money. Click ‘Add to Cart’ now!

## Features

- ✅ PART NUMBER: 45+7.5 MFD uf 370 or 440 Volt VAC Round Dual Run Capacitor.

*by Z***O on Reviewed in the United States on 24 June 2022*

This 45 + 7.5 µF capacitor is a direct replacement for the factory installed dual run cap in my Mr. Cool heat pump.  The terminals are stamped with markings for the FAN, HERM (compressor) and COMMON connections.  That's nice because in a couple of years it will likely be faded and rusty like my old one and hard to tell if not for the stamping.  These capacitors are common failure items and are cheap and easy for home owners to replace,My heat pump compressor would not start once the temperature hit 100°F and I expected it was the cap.  This fixed it up perfectly.  I need a spare to have on the shelf so I don't have to wait a week for delivery.  Local stores were sold out.
