## Overview

The Capacitor AC 45+7.5 uF 45/7.5MFD ±6% 370V/440VAC CBB65 is a dual-run circular start capacitor designed for AC motors, fans, and compressors. It features a robust metal shell, operates reliably between -40°C and +70°C, and supports both 370V and 440V systems. With three clearly labeled terminals and a compact 2-inch diameter by 4-inch height form factor, it offers a universal, durable, and easy-to-install solution for HVAC maintenance and upgrades.

## Description

If your fan is working but compressor not, or the capacitor is bulged on top most likely your capacitor is defective. Round capacitor can be used to substitute oval shape one with the same MFD AND Volt specs. Ombines two capacitors into one unit. Three terminals on the top are labeled "Herm"/"H" for the compressor motor, "Fan"/"F" for the fan, and "C" for the common line.It will power a compressor motor and a fan motor Model: CBB65（Universal model） Shell material: metal Dielectric Material: metallized polypropylene film Tolerance: ±6% Rated voltage: 370~440V Frequency: 50 / 60Hz Safety rated: 10,000 AFC Capacitor dimension: Diameter Height  Operating temperature: -40 ℃ to +70℃ This capacitor is used for start-up and operation of AC motors with frequency of 50Hz/60Hz such as Industrial Grade Replacement for Central Air-Conditioners, Heat Pumps, Condenser Fan Motors, and Compressors. It is small in size, lightweight, heat resisting and anti-explosion.

Review: very good
Review: My A/C was being given its annual checkup. The tech found the 45/7.5 uF capacitor to be weak and recommended that it be replaced. The cost would be $167 for out of warranty and not that much less even if it was in warranty. I declined the repair because it still worked. After the tech left, I went back out to the condenser, removed the corner cover to measure the cap with a plastic ruler for approximate dimensions, and took a picture of the label, and put the cover back on. I then ordered a replacement from desertcart and it arrived 2 days later. The swap was easy and straightforward. I turned off the breakers for the condenser and air handler, removed the corner cover, marked the 4 color-coded wires, pulled off the 4 clips, loosened one strap screw, removed the other, compared the ends of the caps to see if they were the same orientation (they were), installed the new cap, put the leads back on, turned on the both breakers, and saw the A/C was back up and running. I put the corner cover back on and called it a day. It couldn't have been easier to change and I saved over $150.

EDIT: After installing this in late May, the A/C did not work by late August. Had the diagnostic person out, $89 later....the capacitor I had just replaced was dead. Had the second one, he installed it. I do not know how long it will last, but expect to get an all in one for the drawer for next time. Not sure if they sold me a defective capacitor, a really old one...or it's a bad product. Just be aware. Order 2, and learn how to check if it is working every 3 months. 1:1 replacement for my a/c unit's capacitor. Had some yahoo creeps come out to 'service' the a/c. They did nothing but offer: expensive yearly maintenance plan, tell me the capacitor was going out & would be between $300-400 to replace. I laughed at them. They were supposed to clean the unit. they hosed off the outside (i've already done that) and did not even take it apart. Do yourself a favor, buy 1 to have around for your a/c. Learn how to maintain your unit on youtube, save the cash. I paid $10.xx for this capacitor...changed it in 10 minutes. (the tool, a klein impact driver cost me $44, was worth it).
