## Overview

The BOJACK 40+5 µF CBB65 dual run circular start capacitor is a robust, industrial-grade component designed for AC motors in HVAC systems. Featuring a compact metal shell, it supports a wide operating temperature range (-40℃ to +70℃) and dual voltage ratings (370V/440V AC). Its triple-terminal design simplifies installation, making it an ideal replacement for central air-conditioners, heat pumps, and condenser fan motors. Engineered for durability and safety with a 10,000 AFC rating, this capacitor ensures reliable motor startup and operation under demanding conditions.

## Description

BOJACK Dual run circular start capacitor 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 Capacity: 40+5uf Tolerance: ±6% Rated voltage: 370V/440V AC Frequency: 50 / 60Hz Safety rated: 10,000 AFC Capacitor dimension: Diameter Height  Operating temperature: -40 ℃ to +70℃/-104℉to+158℉ 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. Round capacitor can be used to substitute oval shape one with the same MFD AND Volt specs.A 440 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 440 volt.

Review: Works well. - Easy to replace. Slightly different fit but function is same.
Review: Great aftermarket replacement - Worked like a charm when my AC compressor capacitor got weak.

## Questions & Answers

**Q: Where is this made?**
A: The great majority are made in China; Home Depot's "Eastman" capacitors are Chinese. The original in our daughter's unit in Albuquerque is made in China; the disconnect (GE) died yesterday but the capacitor is still working.

My take on it is to always keep a spare run capacitor on hand; they are easy to swap out and a very common failure point. You will likely end up with a choice of a Chinese capacitor or none... which would you rather have on a 100F day? Six out of 927 reviews reported lasting less than a year; some of those were "bad out of box."  Sounds like a good bet to me.

**Q: My capacitor has the same ratings (40+5 uf 40/5 mfd ±6% 370v/440 vac) but only has two terminals. it doesn't have a fan wire. it's a trane xl 16i??**
A: Unable to answer because the part was sent back before opening.

**Q: Will this work in my rheem rp1530bj1na?**
A: Sure will ,if the old one was the same rating

**Q: Will this work for a  b9457-5600 goodman?**
A: If the old one is 40/5 MFD it will work.

### ⭐⭐⭐⭐⭐ Works well.
*by J***. on December 23, 2025*

Easy to replace. Slightly different fit but function is same.

### ⭐⭐⭐⭐⭐ Great aftermarket replacement
*by K***B on January 15, 2026*

Worked like a charm when my AC compressor capacitor got weak.

### ⭐⭐⭐⭐⭐ Simple install, fixed AC without an expensive service call!
*by K***R on May 5, 2022*

My outside AC unit stopped functioning. What was happening is it would hum but the fan would spin. The fan motor would get very hot and then the unit would just shut off. At one point to diagnose it, when it went to go on and it was humming I took a stick and pushed the fan blades to see if they were stuck. It started spinning fine then. After doing some research it lead to the capacitor being bad. It holds an electrical charge and when the machine is turned on, it gives the motor that boost it needs to start up. Kind of like kickstarting a manual car with a bad starter. Not wanting to spend an fortune on a service call, I opened the side panel up with 3 screws and read the values on the current capacitor. I ordered the same value AC capacitor here for real cheap. So cheap it wouldn’t be a bad idea to get another one as a spare. To install it, I just took a picture of the current one to see which color wires go where. There was also a wiring diagram on the inside panel. The terminals fit perfectly and it’s just a metal strap with a screw to hold the capacitor in place. Once hooked up, in the disconnect box I flipped the jumper and then went back inside and turned back on the circuit breaker to the unit. I called for AC and it started right up! Problem solved. This was in a Goodman 2.5 ton outdoor AC unit that was installed in the fall of 2011. So the original part lasted 11 years.
