Hey guys Samsung RB2155BB compressor still runs after fridge is satisfied, then shuts down and doesn't restart. Pull out plug and plug back in cycle starts again. Please assist thanks.

Put it on a powerstrip and toggle the switch a few times a day.

You need to explain this a little better. Are you saying that you are trying to restart it right after it shuts off? It has a safety to prevent this.

I know the fridge has been satisfied everything is good however compressor doesn't shut off until it overheats I guess I remember it being very hot to the touch

I think I understand. Here are the manuals you need: https://dl.dropbox.com/u/8010163/Samsung%20Refrigerators.zip
The file "Samsung_refrig_SAM0075.pdf" may be the closest one to your model. I suspect that you either have a bad thermistor which will require you to test it with a good digital volt/ohm meter and the chart in the back of the book and a thermometer, digital would be best. Also, you need to run through the programming and testing portions. I have been doing refrigeration work for over 35 years and this one is way more complicated than a commercial unit. You could have a stuck relay, too. To test the different thermistors, look on page 80 and at the top left (before rotating page) you will see a white plug where you would measure between GND (2) and the different sensors at 3,4, 5, 7, and 8. You have to know the correct temp and use the chart to find the correct resistance (Ω - ohms). That seems to be the easiest way rather than going to each thermistor to test them. Make sure to check the condenser coils under the unit and see if they are dirty, too. Wash them out if they are.

Now I reset the mainboard fridge runs and cycles for about eight hours or so then quits I have to unplug then replug to start cycle
