Try this, if you can.
Move the refrigerator out into the room and remove the cover ( metal or cardboard, usually) that covers the compressor.
On some models, you may actually have to look up inside the bottom from underneath it.
The compressor is usually round, sort of like a ball, and usually black in color, is usually smaller that a soccer ball.
It may have two electrical switches attached to it, and they should be together, not separate.
One is called a "Klix-on" in the trade.
This is the electrical switch that is supposed to start the compressor. (not the capacitor, that is yet another part).
After you find the "klix-on", plug-in and turn on the "fridge", tap the "klix-on" with a small hammer, and see if the compressor then starts.
If it does, you have found the problem.
I have purchased these for $ 38 locally.
God bless your efforts.
