I needed to replace the relay start and overload protector on my LG refrigerator. When ordering the replacement part I was told that I needed part # EBG31940225 which is the Compressor relay & overload assembly. I got the new part but it looks nothing like the part that I took off the fridge (relay start, capacitor and the overload protector). The new part has the PTC assembly and the overload protector connected to 3 wires (black, blue, pink)on one end and the other end plugs into the fridge. There is also a green wire (ground wire) which is not connected to anything. The old part only has the black and blue wires and the same end piece that plugs into the fridge. The end piece of the new part (that plugs into fridge, I think it's called a butt connector?)has 2 male parts and one female part. The female part which is the pink wire does not have a male end to connect to or make contact with inside the refrigerator. I tried the new part but there was no change (the air that blows in is not cold). The original issue is that the fridge just stopped getting cold, everything else is working properly though.
Can anyone assist me with this? I have been assured that I got the correct part for my model.
Or does anyone know where I can get instructions on installing this part?

That model uses two different style compressors. You might have got the one for the other style. I don't work on enough LG's to give you a definite answer but, wildimaginations is an excellent authorized LG tech and I'm sure he knows and can assist you. I'll send him a private message and see if he can help you. Stand by.

I think you got the wrong part. The old connector has a simple 2 wire connection with a start cap on it. You will have to show the parts people what your old part so they can reorder. Sometimes LG will ship out the wrong part and it can be frustrating.

Another thing you can do is take the old relay to the local appliance parts store and have them test the start cap to make sure it's ok. If it's not, they should be able to match it up with something in the Whirlpool parts bin.

Also try this, shake the old relay switch and listen for anything loose like loose pebbles. If you do hear anything like that, you have a bad PTC and most appliance parts stores can match it up.

Hope this helps.

Thank you wildimaginations and rickgburton!

I have checked the overload protector and it did rattle so I purchased a replacement as well as the other parts that I was told to buy. All of the parts that I ordered are incorrect. I live in the middle of nowhere and there is not an appliance parts store anywhere close so I have to order the parts online. Would you happen to know which part numbers I actually need? I want to replace the start relay (or PTC) and a new overload protector. When I look up these parts for my model (LG LFX25971SB) they all give me the same part numbers that I ordered and they are incorrect. I ordered the following parts and none of them work with my fridge: EBG31940225, 6748C-0004D, 3550JA2042C and 6750C-0004R I know there are duplicate parts there, but that is what they told me to order.

I am pretty sure that part # 2319792 is the correct part I need even though it says its for Whirlpool. (it looks identical and has the same connections, etc) I am not sure what the correct part number to the overload protector for that relay start device is. 6750C-0004R is not right - the prongs are in the wrong spot. Do Whirlpool parts work on LG models?

Thank you SO MUCH for your help. I have been trying for days to get good information on this issue!

The correct part number you need is EBG44308701. Unfortunately, that part is no longer available and there is no substitute for that part number.

Have patience. I will check with my local parts supplier and see if I can get you an alternative part number. Everything is closed till Tuesday.

Replacing EBG44308702 with W10613606 works

This was the first thread I found where someone else had the exact same issue I had, with Pictures!!

The bottom line is that I did replace the LG switch relay (refrigerator model # LMX21981ST) with the whirlpool switch relay part number W10613606 and the refrigerator runs.

The original replacement part I was given (same as originator of this thread) EBG31940234 did fit on, but it would not keep the compressor running for more than 10 seconds.

Many appliance repair shops seemed skeptical that a whirlpool relay would work on the LG, but it does. Thank you. And I hope this confirmation will help the next guy... and perhaps scare people away from buying LG appliances if they do not support them with parts.

I have the same model fridge and its basically no longer cooling. I wanted to try to replace the starter relay but I can't seem to find the matching parts. Here's what my starting device looks like:

Here's what my compressor looks like:

Is this the same situation you encountered?

Also, I did the "shake test" and I didn't hear anything rattling around in there, so maybe my compressor is bad.

Use a DMM and check the parts first before replacing them. If it ain't broke, don't fix it.

OK, for you and anyone else that sees this: AC stands for Alternating Current. It's called that because if you could look at it on an oscilloscope you would see that one half of the sine wave is positive and one half is negative. On 60 cycle current (USA) the electricity flows between 120 volts negative and 120 volts positive 60 times per second. When connecting AC volts to a load it makes no difference which wire goes to each side of the load because one wire going to the load is half positive and half negative and the other wire going to the load is also half positive and half negative.

If my explanation was too complicated, it doesn't matter which wire goes where on AC loads. The start device or relay is a load.
