An easy and cheap fix to replace a broken and obsolete freezer start relay
I used one of these to revive a 1995 upright Kenmore freezer that I use for homebrew fermentations. I moved the freezer recently and after letting it sit unpowered for a day when I plugged it in the compressor would start for 5 seconds then cut out though the blower would continue. The freezer wouldn't cool at all. A bit of googling pointed to the start relay as the likely culprit but that part, which is also used in this era's Whirlpool and Fridigaire freezers, was no longer manufactured and the only one I could find was $60 on Amazon. However it was sold in the marketplace and was shipped from overseas so I'd be taking a chance I could not return it if it didn't work. Continuing to look for solutions, I found a youtube video which showed how the Supco 3 n' 1 could be used to replace the start relay and since it was only $11 and sold by Amazon it was a less risky purchase.The only question before buying it was how much horsepower my freezer had, as that determined which Supco I needed to buy. My freezer apparently was 1/5 HP based on a website I found which equated amp and volts to HP so I went with the 810 as opposed to 410 model. Changing out the start relay and installing the Supco then zip tying it in place was about a 15 minute job. Make sure you remove all of the old starter relay so you can see the 3 pins on the compressor where the Supco connects and you then connect the two power wires from the old start relay to those on the Supco. The freezer immediately started working correctly again and has been for about a week. It is running more efficiently that it did with the old start relay based on how much electricity it is using now versus running with the old start relay as shown by my Kill-a-watt meter. Not bad for a 22 year old freezer.

Great product
I used to be a service technician and I have often used Supco products for cost effective and easy to install replacements for factory parts that are far more expensive. I have never had a problem with them failing so I feel that I can recommend these products for out of warranty equipment. I used this product to replace the start relay, overload and capacitor on a refrigerator that somebody had given me. The man didn't know what was wrong with this refrigerator as it occasionally wouldn't cool. I got it home, plugged it in and heard the familiar sound of the overload device as it clicked open because the compressor wouldn't start. I waited as it went through several cycles and finally it started. The refrigerator cooled but when it cycled off on the thermostat it wouldn't start again so I was confident that there was a problem with the start system, I checked online for replacement parts for this brand of refrigerator and they were far more expensive than what I was willing to spend so I ordered the Supco product.as a replacement. This is probably a product for a person who is somewhat familiar with compressors, wiring diagrams and schematics as it's not just a direct factory replacement part. However, I have always been satisfied with Supco products. This refrigerator works wonderfully and I'm thankful for is as it is newer and in better condition than my old one. .

Good replacement part but not for my fridge
Nice replacement. Unfortunately wrong model and too late to send back. You have to ensure it fits your fridge type. It does NOT fit a Kenmore Elite model. Its really easy to change this item ( I forget its official name) on the fridge. Just go to Youtube to see how its done. If you have a Kenmore, go to SearsPartsDirect website, enter model of your fridge, then look up parts. When you see the part number for this thingie, get it from Amazon. Literally half the price! Sears is very inflated, which is why they are out of business. This gadget is super easy to install from the back of your fridge. No issue at all. I got the right part and did it myself. No technician needed.

Keep one around for when fridge stops working!!!
Excellent value. A must to have on hand for if your fridge stops cooling! High quality build, no perceived noise, and perfect fit and quick to switch on. Fridge stopped cooling, tested the relay and it was bad, so ordered one of these to see if it worked as advertised and because I could get it quicker than a replacement relay and it worked perfect. I could've used this long term but replaced the relay with correct part and now I keep this around as a temporary fix for if it happens again, because it would save hundreds in food cost.
