Question about Refrigerators
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?
A 6ya expert can help you resolve that issue over the phone in a minute or two.

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

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.

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 :)

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.
