I can help if you check and correct the model #.

Your compressor pinout should be as follows, common, top, start pin bottom right and run pin, bottom left.
Either that, or the triangle arrangement is upside down with common on the bottom. Ohmeter check should show common to start about 4 ohms, common to run, about 3 ohms. Start winding usually higher resistance.
If you hold the ptc device with the tab on top and input spade terminals facing you, resistance from the left input terminal should show short to the left output compressor terminal and 5 ohms to the right output terminal.
Generally, I do not recomend using a ptc device that was not listed as a replacement as you can burn out the compressor if you wire it wrong. One fridg power wire goes to the left ptc input terminal, the other to the klixon overload, run capacitor between the left and right side ptc input terminals. good luck.

Ok to make this more simple the OLP seems to be working fine, but the PTC needs to be replaced. I am just trying to find a PTC with the above Klixon part number which is less expensive than the LG labeled one. I am sure that others have installed a PTC with the same Klixon part number into a brand other than LG but labeled with a part number supplied by the manufacturer of the refrigerator.


It is just so weird that nobody seems to have made a cross reference of different refrigerator manufacturers (LG,GE Whirlpool etc.) part numbers using the actual part makers (Klixon) part numbers. The Klixon part is a 8EA3B3 (replaced by 8EA21C3) which has specific properties that do not change just because it is in a GE, LG or what ever manufacturer.

Anyway here is a link to the 4TM & 8EA Klixon products with some but not all of the technical data.

Also here is a cross reference of the Klixon 8EA part numbers for reference.
