My refrigerator does not cool on both sides.
Answer Hello Raul. You will need to test for power from the main board to the compressor start realy on the unit. No power means to replace the main board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
I have RSG5FUBP , compressor model ( EQ4A5Q-L2X) stop working .
How I can test the compressor without the PC Board DA41-00524A?
Also I want to ask what is the cause of failure ?
To test the compressor windings you would do a resistance check of the pins on the compressor. If you go across the 2 that the relay would go on and read the ohms then go from each of those to the 3rd pin. The ohms reading from the common which is the 3rd pin to each of the other pins, when you add them up they should equal to about the same reading you got across the start and run pins.
