SUPCO SPP6 Relay/Capacitor Hard Start Kit with 500% Increase Starting Torque

I do recommend this product. It seems to work well I’ll update on its battery life. Let’s see if it last longer than the generic one that I bought 2 months ago which was garbage it broke after only 1 month of use. This one was easy to install i replaced a cheaper one that broke very quickly; it seems to work much better than my last generic model I bought here on Amazon.

This worked great. I have a champion 3400 generator inverter and it would not start my 13500 btu dometic brisk air 2. At first I thought it was my generator not putting out enough watts but I tested some other things and was able to put out up to 3200 running watts. Turns out my ac pulls up to 8000 watts on start up for that split second and was overloading my generator. Very frustrating because it's the whole reason I bought the 3400. I did alot of research and read about capacitors and how they work. From what I understand these newer air conditioners come with very small hard start capacitors. I'm sure they do it to try and save on costs. So I figured for 13 bucks it's worth a try. Installation is very easy you just piggy back it to your stock hard start capacitor it plugs right in. The hardest thing for me was trying to figure out where to mount it. Anyways my generator now barely throttles up when I start my ac. I can even start my ac on econ mode on my generator. I also tried my buddies honda 2000 and it started right up. You wouldn't be able to run much more but it did start it and ran my ac just fine. So do your research because this saved me tons of money I was pretty close to buying another generator to pair up with my original. Make sure you look at your compressor on your ac. The lra on mine was like 67 that's your starting amps. 67 amps times 120 volts equals 8040 watts. I don't know for sure how much the spp6 cut my starting watts down but it has to be under 2000 watts. I highly recommend.

My outside AC unit (14 years old) was not working correctly - the compressor was not coming on, and the fan required me to push it to get it going. These symptoms are usually associated with a bad capacitor, and I ordered a new one. I also found out about this product, which gives existing capacitors extra power on startup, so I ordered this as well. The hard start relay came first, so I hooked it up to my old capacitor, and just this addition was able to get everything working. When my new capacitor arrived, I installed that, and kept the hard start relay hooked up. My AC unit fires right up, just like it was brand-new, and everything is working as well as it did when it was brand-new. Although I technically did not need this hard-start relay, but I think that leaving it in will extend the life of the capacitor by helping ouyt with teh compressor startup (which puts the most strain on the capacitor. overall, I'm very happy with the product, and saved thousands of dollars by not having to buy a new AC unit.

It's fine; it does its job.

My simple AC kept tripping the breaker for no apparent reason. Three technicians out to check and no answer as to why. The last technician recommended I try installing this before we went any further, I did and since then the air conditioner is performed flawlessly

My heat pump quit doing heat pump things, I tested the capacitors and they were bad, including the hard start capacitor. I installed it and it turns out the compressor was siezed, however, I tested the downstairs heat pump and found out the hard start capaciotr was bad on it also, I replaced that one and the unit became much less noisy on start up. The one I replaced was 13 years old, I will probabaly replace the Heat pump before this one goes bad.

Bought this capacitor not expecting much - cause its so cheap. Did not take long to get it, thanks Amazon! Bought a cheapo Generator (All Power America APG3012 3,250 Watt 6.5 HP OHV 4-Cycle Gas Powered Portable Generator - search for it on Amazon ) - and found that it could not start my RV/AC without some hysterics - literally the generator started to walk across the driveway trying to rev up enough to start the compressor on the A/C. IT would eventually kick in, but I wanted a better solution. Took about 15 minutes to put this capacitor on my 2002 Dometic 13.5K BTU A/C. Which did have a starting capacitor - bout 1/2 the size of this thing. I just wired it in parallel as there were lugs to do so on the original starting capacitor. And sure enough! The A/C compressor started, the Generator surged just a bit under the strain, then returned to normal speed - I base this on how it sounds - dont have a A/C volt meter. But worked very very well. I've run this combo for several hours to test the capacitor and the generator - no real issues other than if i run the A/C i can’t run really any other high amp device such as a microwave, but hey I didn't want to lug around a really heavy generator for camping and having some A/C while in the desert is fantastic. I should mention, that the Generator can start the A/C when it’s first turned on, but when the system pressurizes - that’s when the generator could not re-start the compressor easily. Now if there is at least 45 second between compressor cycles, this capacitor makes the next start of the compressor pretty painless without much struggle by the generator. I was told by someone that works on A/Cs that when the system is pressurized the compressor takes more power to start. For what its worth.

This Hard Start Capacitor is just what older A/C Condensers need. It helps them spin up quicker and definitely extends the life of the compressor. For the price of the kit, as compared to the overwhelming price of a new HVAC unit, it is well worth the small price for the peace of mind of being able to keep your condenser unit running at it's peak performance for as long as possible. Great product and very affordable price. I'm satisfied.

Worked great !!! Installed on my condenser because compressor was having issues starting. Completely fixed it

Conforme à la description, fonctionne bien, aide énormément au démarrage du compresseur de mon climatiseur. Facile d’installation !

Installed this to my 1994 motorhome a/c dometic system. Definitely boost my dometic a/c compressor starting operation. the only suggestion I have is to make the C label abit bigger so it's easier to see.

Excellent product Helps to start my old central air conditioning

Speedy delivery & good products. Very easy to install & perfect for DIYers.
