Great alternative to the expensive GE branded ones and is functioning just the same.
By John Wing
I needed to replace the start capacitor in my outside air conditioning unit, the original one went out and I didn't want to have to go out there and short out the feed wire every time I wanted the A/C on. Luckily it wasn't too hot the week that it went out, and my wife and I both work 1st so we weren't home during the peak heat hours of the day. I have Prime so I received the replacement quickly, and had it installed before the weekend. The installation was a breeze and saved me a couple hundred dollars not paying an A/C guy to come change it. The capacitor has been working great now for about 2 months with no issues, and if it lasts as long as the original it should be there for at least another 7 years. When it comes to capacitors it is not a question of whether or not they will go bad, but a question of when. The higher quality ones will last for a good bit, and in my experience if it is a low quality one, it will go bad very shortly after you first charge it. Since it has lasted for 2 months with no issues, I am pretty confident that it will last for a number of years to come. This one is about half of the price of the GE version, and as far as I can tell the only difference between the two is the label. I am going to get another one, just as an emergency backup because with my luck when this one fails, it will be the hottest day of the year.
***------This is not part of my review, it's just if you want to know how I installed mine------***
It is really simple to install, so if you know how to use a socket ratchet to take the access panel off, and a pair of pliers to pull the wire terminal spade crimps off the old one and push them on the new one, than you can do it yourself. ***Just make sure to pull the service shut off from the box, usually on the wall by the unit, or go to the main breaker and flip off the main breaker for the A/C.*** Just fair warning, capacitors store electricity to be used later. They are able to release all of this electricity all at once, which is a lot more than the electrical energy that is supplied to it. This stored charge can last for days in some cases even after power has been shut off. Just because you are replacing it because it is not starting the unit does not mean that it doesn't any longer hold a charge, just that it doesn't hold enough to start the fan motor. Take this into consideration when removing the old one, and don't bridge any of the contacts. Bridging any of the contacts together with an electrically conductive material (metal wrench, or socket wrench) can cause it to discharge and if you are touching the conductive material, the charge will try and find it's ground through you. I have seen others discharge them by taking a large rubber or plastic handled screwdriver and bridging the supply (Labeled 'C') and feed (Labeled 'FAN') contacts while holding onto the handle, not touching the metal. This works, but to me is not the safest way. The safest way to me is to take a multimeter and touch each of the contacts, this will allow it to discharge and let you see how much charge is remaining so you will know when it is safe to work with.
The capacitor is usually located behind a small panel, most only have 1 or 2 screws holding it, and is above the cutout section where the lines run in to the bottom of the unit. To install it you just have to take off the bracket holding it; remove the wires, each are colored separate, by pulling on the wire crimp terminal (***Not The Wire*** you will pull them out) and match them to the new capacitor. Mine has a Red, Purple, Yellow, and Brown wire; yours may be different and if they are you need to refer to the wiring diagram for the unit if you forget which is which after pulling the old capacitor. To match them, look on the top of each capacitor and you will see a marking/symbol (this capacitor has 'C', 'FAN' and 'HERM') next to each of the spade posts. Just pull the wire from one, and connect it to the post on the new one with the same markings. On mine, the 'Purple' and 'Red' wires went to the Supply ('C'), the 'Yellow' to the Compressor ('HERM') and the 'Brown' to the Feed ('FAN') Each post has multiple male spade connections on them, these are so you can connect the wires in different ways as to make it work without shorting them out, just choose which connection works the best for your install. Make sure none of the metal parts are only touching metal on the post it is supposed to be on, and not any of the other posts or wire crimp terminals, so nothing will short out. Once everything is good to go, just replace it back in the unit, close it all up and then turn the power back on. For someone that has never done this before it may take about 30-45 minutes, less if you are comfortable with dealing with electronics.
I am not by no means a licensed A/C repairman but I have been working with electronics, big and small, for almost 2 decades, so I am pretty comfortable with stuff like this. If you don't feel you have the ability to replace this, please call someone that does. It may be a simple job to replace, but there is a lot of electrical energy going through there, and negligence can cause extreme bodily harm and even death. I am in no way advising someone to preform this task, only giving them guidance on how I was safely able to do it should they feel the need to it also, therefore I am not liable if you do this incorrectly and electrocute yourself.

YEA... . It works...
By Patrick A. Mcgovern
Replaced blown Capacitor.... Had to have AC guy come and fix. He did not have this size with him so he put in a different size and told me he would come back with correct... Charged me 100 bucks cause it was on a SATURDAY... Told him not to bother since it would cost me another service call to come back... Ordered this and changed out.. I will keep a spare on hand from now on... Works as it should. Anyone with an AC unit should have a spare on hand... Easiest thing in the world to replace and usually fixes your AC problem.. If you unit is turning on, but the FAN and compressor is not turning on you can bet it's this part... This one is less expensive than the comparable GE model and works just the same...

Air conditioner compressor fixed!
By M. G. Forbes
Fixed my air conditioning compressor myself. I was looking to see how many thousands of dollars I'd be out to replace the compressor when I found a website discussing common failures. One that was mentioned was the starting capacitor. Good ones are supposed to be flat on top, like a tin can from the store. Mine had a tall dome-shape like it had been inflated. Could this be a hint? Yep! Swapped out the cap (3 leads, easy) and it all works fine now.
