Fridge with a SUpco 3 n'1 start unit

I have a Maytag fridge (5.5 years old). 2 years ago a repairman put in a Supco 3n'1 Start unit because of hard starting. At first it was great, we never heard the unit struggle to start but as time went on it would start struggling again. I just shut it down to defrost the layer of ice in the bottom of the freezer (I see from other posts that this is common) and while the fridge was running to cool down again it tripped my GFCI circuit and keeps doing so. Do you think this is a bad Supco unit or a blown compressor or worse?

    Frig runs and cool properly and produces ice fine. About every 8 to 10 hours

    the frig trips the GFCI circuit. Once reset, it runs for another 8 to
    ten hours before it happens again. New GFCI plug was installed, still
    same problem.

    Frig does not seem to be overheating. Please Help... Thanks Vince.

SOURCE: Need to Install a Supco 3 n 1 start capacitor

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

SOURCE: Compressor problem, installing the Supco 3-in-1 Relay

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.

SOURCE: i HAVE A PROBLEM WITH COMPRESSOR NOT KICKING ON

Actually you should check also the thermostat control, if you know how to ypass the thermostat control then do it just to check if your compressor running smoothly, well it should be since it was newly replaced,

well if runs, then your problem is your thermostat, but if not then check your supply current if it is stable or under voltage, if it is fluctuating then better yet put a UPS (un interupted power supply) or AVR (auto voltage regulator for your sensitive appliances cause it might also affect other appliances.

If your electric current is stable, then check the controls of your refrigerator, if it is electronic then try to test it with the service center but if it is manual then try to put starting capacitor for your compressor, it might be hard starting,

hope this will help

Hello, Unfortunately the compressor likely is seized now. There are a couple of reasons that the original start device failed, 1) faulty connection. 2) poor quality part. 3) compressor was running non-stop due to other deficiencies in the unit or 4) the compressor was failing to begin with. The compressor may indeed check out ok as far as electrically ( windings ) but the mechanical component ( rotor ) has locked/seized up. You can determine whether it is the windings by checking the ohm value between common to start, common to run and run to start ( c-s, c-r, r-s ) and look for values similar to 6ohms, 3ohms, & 9ohms. Then check the start and run & common windings against the compressor casing to see if windings are shorted. In order to double check the mechanical component you'd need another hard start, ( or a test cord direct to 120vac, but that should only be done by an experienced tech ). nothing else will start it at this point obviously or you wouldn't be using a hard start already. The other unfortunate issue is this, many of these compressor's have a 10yr. parts only warranty but that was voided as soon as the 3in1 hard start was installed. In the end I'm likely not telling you anything you didn't already suspect or know in fact, but it is likely the compressor. I sympathsize, seized compressors **** ! Hope this answers your question and moves you forward. good luck macmarkus :)

SOURCE: Supco wiring an old freezer. Orange wire?

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.

Emerson model#CR519B. The unit just stopped working. If plugged in a motor runs for about 8 seconds and clicks off; about a minute later it repeats. Help


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.

check the amp draw on the compressor the windings could be bad.if the amp draw is really high change compressor. If they are where they should be change the 3n1 and make sure cond. coils are clean and fan is operating properly

MAYTAG SIDE BY SIDE MCD2656KGB WAS BUZZING ON START UP SEVERAL TIMES AN HOUR, THEN QUIT COOLING AND FREEZING. I REPLACED THE CAPACITOR AND START RELAY, BUT IS STILL DOING THE SAME THING?


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

Maytag fridge stops cooling, then 1-2 days later restarts on own


The buzzing is typically gonna be the compressor trying to start and failing. Am I right in saying the fridge is at least 12 or more years old?

Maytag used to use a compressor made by Tecumseh and they had a problem with starting. They would buzz and sometimes start back up. Sometimes in a few tries or a few days or never. It would continue to re try every couple minutes and last 5-10 seconds.

I would verify if it is a Tecumseh or an Embraco compressor then make your decision.

A service tech should be able to figure this out pretty easily! Normally what I would do is if I go in and it is running then I would turn it off and back on right away. the fridge will go through its restart sequence and typically make its noises then. Hopefully you are not being charged every time they come out

Compressors are the most expensive repair! and on these I always replace the discharge tube since they tend to rot out from sitting in the drain pan.

Let us know what you find!

The compressor starts, (or tries)for ~ 3 seconds, stops. retires ~ 15 seconds.


You either have a problem with your compressor start relay/overload assembly.......or you have a bad compressor. You would need the model/serial number for the correct part. If the unit is out of warranty, a 3 in 1 hard start kit (Supco URCO41) can be installed. Disconnect unit from power prior to attempting repair, and follow the instructions with the part.
If the product is under 5 years, the compressor may still be under manufactures warranty. In that case attempting a repair would void the warranty.
