Looking to install a supco 3 n 1... any advice? good idea?

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.

The link above has all the download links for the software.

I’m happy to help further over the phone at https://www.6ya.com/expert/paul_0af9b1d5c0eb4fc3

you will remove power from unit , remove old receptical cut wires close to old unit then splice new wire into old polarity is not important

Was the orange wire on a switched live on the old compressor connections? It may come on when the compressor goes off in that case. If not, recheck the schematic for the other end of the heater. If it has a neutral, join the orange to the live feed to the supco. If it has a live, leave the orange on the neutral of the supco.

compressor connectors are usually marked S - start white wire from supco start kit, C - common - black wire; R - Run - red wire. Check my video, that will give You better Idea. Thanks.

Most likely you will need a Supco 3 in 1. It's a capasitor, relay and overload assy. You can buy the exact replacment at http://www.partselect.com/MultiModels.aspx?ModelNum=mzd2766&searchTerm=img_53200&RefineSearch=0&imgMfg=Maytag parts #4 and #6. They cost a total of $83.35 plus shipping. If you go with a Supco 3 in 1 like I have suggested you can find it at http://www.appliancepartsonline.net/index.php?target=products&product_id=207 for $21.95. It's very easy to install. It only has 3 wires that go on the compressor and two that you connect the power to. The instruction are on the part and very easy to understand. The 3 in 1 is also a much stronger part and will out last the factory part by a long shot. 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.

3 in 1 starters like the supco that you have pictured can and will cause premature failure of your compressor. newer compressors are not designed to handle the start up current the 3-n-1 provides. I reccomend replaing wiht an original oem part the part number is 8201786. If you still want to use the hard start use the 410 model obviously hook up the red white and blak wires to the compressor the 2 left over leads will connect to the 2 original wires that come in to the compressor I beleive they are red and white. polarity does not matter. good luck Peyton
