Review: Worked perfectly for me! - I bought a condo and it has a Frigidaire refrigerator, not the prettiest thing but it worked perfectly. One day I came home from work with some ice cream and when I opened the freezer it obviously wasn’t cold and the ice was almost completely melted, and the fridge part was warm, too. Figures that it happened 4 days after I had went shopping and stocked up on a bunch of frozen stuff. I looked at the tag inside and it said it was manufactured in 2003, so it was about 14 years old. I looked online and saw that a replacement motor on it was about $300 for the part alone, so I figured I’d just buy a new one. But while looking all this up I came upon websites saying that it’s rarely the motor that goes out, but the more often it’s the capacitor or start switch, and it’s an easy, inexpensive fix. That made me look into things deeper. I read websites and watched YouTube videos and somewhere along the way found a link to this item. For less than $10 and free 2-day shipping with Prime, definitely worth a try before shelling out the cash for a new fridge. After I got the part I pulled my fridge out, unplugged it and took a look. I don’t really have any experience doing work like this, but at my old condo we had a brand new GE Profile fridge and over 10 years we had repaired at least 3 times at about $200 each repair. The mechanicals of my Frigidaire looked nothing like the videos I had seen. Most of them seemed to have the capacitor plugged into the motor with the start switch connected to it, but mind had the start switch connected further inside the fridge. Still, since I was going to get a new fridge if this didn’t work I figured what did I have to lose by trying?? So I did made my best guess and unhooked the start switch then pulled out the capacitor. Sure enough, just like the internet said when I shook the capacitor, I could hear the broken pieces inside rattling around. It took me about ten minutes to hook up the wires to the Supco all in one. I took a good look at everything to make sure all the connections looked good, then I plugged her in, went around front and turned the fridge to cold, and she started purring like a kitten. A few seconds later I could feel cold air blowing in both the fridge and freezer. It worked!! Some websites and videos said this should only be a temporary fix until you get the expensive replacement parts, but other said it’s fine to keep it permanently, so that’s what I’m doing. Three weeks in it’s still working perfectly. I can’t believe how inexpensive and easy it was to fix my own fridge! I’ve been telling friends and family about it ever since. I kind of hope that someone else’s fridge will break so I can look like a hero when I fix it for them. :-) Anyway, I definitely recommend this part and also that you watch videos and read websites because that helped me in a big way, both in confidence and seeing how different brands of fridge look different inside. Save your money and fix it yourself with this!!
Review: Universal enough to even fix a 1970s Frigidaire Freezer! - I have a Frigidaire upright freezer that was built in the late 70s that was starting irregularly and the compressor was getting hot. The starting mechanism was clicking and rattling several times before the compressor would finally kick on. With the parts being obsolete, this hard start kit did the trick and fixed my freezer. The compressor kicks on effortlessly now and I am no longer concerned about the freezer breaking down completely. Install was easy using the diagram on the package and cutting 2 easily identified wires to splice in the kit with the supplied wire nuts. I added electrical tape for a secure connection then zip tied the assembly to a metal crossbar near the compressor. It's been a few weeks now and I am so glad I found this kit to keep my freezer running because they don't make them like they used to anymore and my freezer is a tank with a new lease on life.

## Questions & Answers

**Q: So i bought this in june, 2014 and it fixed my fridge.  but a few days ago my fridge went warm again.  do typically last a year?  should i buy another**
A: Just remember your basic math when determining HP ratings.  1/12HP is a lot smaller than 1/2HP and so on.  Too make it easy, just think about this.  If the bottom number is bigger, the HP is smaller.  If the bottom number is smaller, the HP is bigger.  Its very important to choose the correct ratings when installing the Supco start kits.  If the rating on the start kit is larger than your compressor rating, the overload device may not activate in a timely manner.  And compressor will over heat.  Don't trust that the compressor will shut down when it gets overheated!  Most, but not all standard home fridgs, and freezers are relatively small compressors.  1/12 to 1/5 HP.   A  1/4 to 1/3 Supco start kit may overheat the compressor on these home fridges and freezers.  A compressor needs around 2 minutes of rest time between cycles to start properly.  Thats the overloads job is to wait that time period.  The proper Supco will shut down compressor if the 2 minutes between cycles is not sensed.  Usually, if compressor does not start in 2 seconds, proper Supco will shut it down, and wait for the 2 minute window, and try again.  The proper Supco will protect you from..... kids in and out of fridge too many times at once,  door not closed all the way,  standing there with door open looking at food to eat.  LOL!!!   We've all done it you know!!  LOL!!!   Anyway, just really match your ratings of HP up with the proper start kit.  Don't think you can just over match the ratings and it'll work just fine.  They will work, BUT, better be safe, than sorry!  Choose the proper rating for your fridge,  or freezer.  I know, because I've already been experimenting in detail with this very issue.  Hope this helps all you guys out there.

**Q: What is the difference between the supco.  urc0410 and the  rc0410 ?**
A: Supco urc0410 is used on refrigerators without run capacitors. Per their website Supco rco410 works on refrigerators with or without run capacitors.

**Q: Is can work with Jennie 15.9 upright freezer**
A: Yes, it should if the compressor is just having a problem with starting. These are boosters & not actual hard start components. Watch your wiring. My compressor had no terminal markings. (c-s-r)

**Q: Is it work for compressor with 1/4hp 21.2LRA?**
A: Supco claims 1/4 to 1/3 HP for the RCO410. See their PDF datasheet for details. There are sockets on the wires to suit the three 2.3 mm pins used on most fridge compressors. If you are going to utilize the original thermal overload switch (best for compressor life), you may need to replace one socket with a 1/4 inch spade terminal.

### ⭐⭐⭐⭐⭐ Universal enough to even fix a 1970s Frigidaire Freezer!

### ⭐⭐⭐⭐⭐ Fridge start kit
*by A***2 on September 22, 2014*

I ordered this for a bottom freezer refrigerator that I was having compressor start problems with. I was preparing to buy a new fridge prior to finding and researching this start kit. The compressor had finally quit starting and running even after buying and installing a new oem starter for the fridge which was more expensive than this Supco kit. I had previously tested the ohms on the compressor and it checked out fine with no grounding at all to the compressor case from the pins. There are good videos on youtube on how to test your compressor and how to install this kit. I believed that my compressor just needed a stronger capacitor to start and once started it would run just fine so I took the chance and ordered this Supco start kit . I received and wired in the Supco start kit using the package instructions and the only difference was that my oem switch had three wires, two white and one blue. I wired the two white wires to one of the Supco wires and the blue wire to the other and the fridge started right away and ran just fine, I couldn't believe it. No buzzing, no humming or any other issues. Some say these are temporary fixes suggesting that the compressors are on their way out if they won't start with the oem started and others have installed and ran these for months or years on their refrigerators. I have been watching my fridge closely after since this installation and after two full days of running flawlessly I am of the opinion that this starter with its larger capacitor is more in line with the capacitor size that these refrigerators should have installed on them when new instead of the marginal sized capacitors on the oem switches. Before this fridge I had an older fridge that ran for over 25 years with no compressor problems and I did not have to change one part on it during that whole time. I have replaced the electronic board on this existing fridge after only 6 years and after 9 years now the compressor was not starting and the new oem part wasn't starting it either. They do not make them like they used to! Remember this is my opinion and of course I will wait and see how long this will last but the fridge hasn't missed a beat since the Supco was installed. Opinions, as you will find when you research this part vary greatly so you have to listen to all sides no matter how ridiculous some of them sound and decide. So far I have saved or extended the life of my almost 1100 dollar fridge and only time will tell. If it goes again then I will concede and buy a new fridge because compressor costs and the tools to change them are just too expensive. I will update if this fix last less than 6 months.Thanks for reading and good luck fixing your fridge. Update: 12/18/2014 This part is still working fine but my compressor finally bit the dust and won't run so I guess it was on it's way out when I first had the start issues. I did however, get an additional 3 months use out of the fridge using this part.
