Need to Install a Supco 3 n 1 start capacitor

I had the same problem with a small wine cooler. It happened to me twice in 6 years. Both times I had to replace the starter relay.

I couldn't find any repair facilities willing to work on these small wine coolers or refrigerators, probably because the bill would be more than the used fridge is worth. If you feel confident around a volt/ohm meter and electricity, you could learn how to test this and maybe fix it yourself.

You shouldn't do any of this if you aren't familiar with using a Volt/Ohm meter and can safely and confidently work around electricity.:

1. Unplug the fridge
2. I first tested the compressor with an Ohm Meter (see how with youtube video below or by reading how at Davesrepair.com). It was good, but it kept starting and stopping within a few seconds.
3. Basically my starter capacitor/relay wasn't working. It supplies temporary starting voltage to the starter relay in the compressor, then cuts off to allow the motor to run.
4. I bought a Supco 3-in-1 on Amazon for less than $13 and hooked it up according to the supplied instructions. It lasted about 3 years.

Of course, the factory recommended repair is to buy the original replacement relay, but it will be more costly and harder to find.

I bought a Supco 3 in 1 Hard Start relay sized for the HP on my compressor. Mine was the Supco RCO810 (see link below).

NOTE: Before I replaced the starter relay and overload protection with a Supco 3 in 1, I learned how to test the compressor with a Volt/Ohm meter. If you don't have a meter, you can buy them online or inexpensive to free with a coupon at Harbor Freight.

• Here's a typical youtube video to learn how to test a compressor: HVAC Ohming Compressor Windings
• Also, How to Test Refrigerator and Freezer Compressors by davesrepair.com is a good resource. He also has instructions on his website on how to build a tester to start a compressor without a relay to see if the compressor starts/runs.
• Where I bought my relay: Supco RCO810 3 1 START Hard Start Kit
• Good youtube on how to install a Supco: How to Install Universal Relay 3 1 Starter on your Compressor

I would avoid even using this device. there is a good possibility it will burn out your compressor. Most compressors have a run capacitor tat improves the power use and if it is not in the circuit the compressor can be damaged. I advise using the correct start device for this unit.

It's very simple to install a 3N1 Supco Hard Start Relay, Some refrigerators have a run capacitor located on compressor or mounted nearby. It will be important that you use the run capacitor in with the 3N1 Hard Start. Here is a Photo of the=> URCO810_3_N_1

The instructions come with the 3N1 Hard Start Relay. Can you please post the model number of your refrigerator here so I can look up a wiring diagram? Look around the fresh food section door frame for your model number. I do need to know so we can get the right run capacitor in the 3N1 hard start circuit, Thanks Sea Breeze

sounds like you have a unit that may have bit the big one... there is one more alternative if your willing to give it a try.. the sale a 3-n-1 start assist that goes on the unit.. it has the capacitor and relay built into device and in a sense is a hard start for a froze compressor ... its last resort and i have seen some work for years after installation and others within a day back to same originally results needing a new compressor ... they are easy to install and actually have a diagram on them... you will have 2 power wires that just wire into the current power wires... supco 3-n-1 is one brand to try.. whereever you got the relays should have these devices... again its last resort but may save you several hundred dollars right now... good luck

you can replace the relay with a 3 in 1 made by supco. i generally just use a supco 0410.

it is a start relay, overload, and start capacitor all in one. works great for residential systems.

Hi, If the 3 posts are top center and bottom right left, the black wire goes top the top center post. The red wire will go to the bottom right and the white goes to bottom left.
If the posts are bottom center and top right left, the black goes on bottom center and the red goes top left. The white goes top right.
If you do not see a capacitor, disregaurd the wires in the 3-1
I hope this helps you. Please let me know if I can assist you further.

I would go back to person who gave that advice because just the right touch on that capacitor and YOU my friend will be in the hospital. If this is helpful, please post as such. TY

Installing Hard start Kit 3n1 Supco.

hi thanks for the question . i would replace the relay and the cap then your sure your good to go. thanks te appliance doc rate me please

ok check if fans go on

you probably have an defective compressor relay/overload

you can buy an replacement at an appliance store.

supco make them just ask for an relay overload combination for 1/4 1/3 hp anyone with some electric knowledge can help install it if it dosent start up, well bad compressor hope that this helps
