Samsung RS2555SL Side by Side Refrigerator

Refrigerator or freezer does not come on... No cooling at all. I have power to the control panel with all the lights on the panel. I power cycled it to try and reset with no success. I unplugged the ice maker, but this killed all of the indicators on the control panel.

First, check to see if the light comes on or if there is any fan, motor, or other sound coming from the appliance? If so, the refrigerator isn't really completely stopped--go to the specific problem you are having. If not, try adjusting the thermostat to a colder setting. If that doesn't work, read on.

Second, check to see if there is power getting to the refrigerator. To do that, plug a lamp or other device into the same outlet the refrigerator is plugged into. If there's no power, check the fuses or circuit breakers. If the fuses or breakers aren't the problem, contact a qualified electrician to restore power to the outlet.

If there is power to the appliance but it still seems to be stopped, there may be a problem in one or more of these:

  • Wiring

  • Thermostat

  • Defrost timer

  • Compressor

  • Overload and/or relay
If you are unable to troubleshoot the problem from here, you may need to contact a qualified appliance repair technician.

    Hope that helps you get a general idea of what could be wrong. However, as you can see, there could be on of many things that could be wrong. Hence, in my honest opinion, it is best to get a repair guy to diagnose and resolve the issue.

It's not coolIf the refrigerator isn't cool, you need to answer some questions, then see if the compressor is running.

First, answer these questions:

  • Is the refrigerator completely dead? If so, see “It's stopped completely.”

  • Is the thermostat knob turned to the proper setting? If not, reset it.

Next, see if the compressor motor is running

The compressor is a football-sized case with no apparent moving parts. It's on the outside of the refrigerator at the back near the bottom. If it is humming or making a continuous noise and your refrigerator is still not cooling, there may be a more serious problem with one or more of several different components, we recommend contacting a qualified appliance repair technician for further help.

If the compressor is not running but you do have power to the refrigerator, there may be a problem with one or more of these:

  • The compressor

  • The Thermostat

  • The overload, relay, or capacitor

  • The defrost timer

  • The condenser fan motor

      1. You need to use thermometers. Test the freezer temp for a while. Then the refrigerator compartment for a while.

      2. Does the compressor run AND also the evaporator fan run (the later
      of which is located in the back wall of the freezer compartment)? They
      should be.

      3. Do you see any water down in your drip pan that should be either
      located under your refrigerator (accessible by removing the grill at
      the bottom front of the refrigerator, which just snap off and back on),
      or ontop the compressor at the back? If there is no water at all, based
      on your symptoms, you could have a case of frozen defrost water at the
      cup that allows this drainage to go through the cup and then tube, back
      of the refrigerator and down a tube into the drip pan. Check for ice in
      and around that cup which is located at the top rear of the
      refrigerator compartment. If that is clogged, chances are ice has
      formed, blocking where freezer air gets into the refrigerator
      compartment at the upper rear of the refrigerator compartment.

      If this is what has been going on, what I do is...first unplug the
      refrigerator...then take food out of the freezer and put it in the
      kitchen sink basins and blanket or towel over it to keep it froze. I
      also move out of the refrigerator compartment the food most likely to
      spoil quick... like the milk, and some other stuff, and to clear away
      stuff in the area of the defrost drain cup. Then I use a hair dryer to
      thaw for a bit back at that cup. Then when I can tell that the cup is
      thawed...then I pry off the flexible rubber or plastic cup and then use
      a piece of tubing I carry with me, and put the tubing (you can buy this
      at home centers, hardware stores and auto stores) and jamb it in the
      defrost drain tube hole and blow and see if you are able to blow out
      any gook (if your tube is a little ill-fitting you may have to wad a
      rag or toweling aroudn your inserted tube to get a better seal when you
      blow). When you know you are able to blow through the line and see
      evidence of it in the drip pan below, then you can replace the drain
      cup. You may also be able to do this job from reverse by simply
      removing the drain tube from below, where it sets in (just above,
      actually) the drip pan below, and then blow *up* the drain tube. After
      doing this, knowing the tube and cup are clear...Then place the
      hairdryer in the freezer compartment...shutting the door on the cord,
      and let it run inside to defrost the refrigerator. Then the thawing ice
      from the evaporator coils and maybe around the fan will thaw and run
      out into the cup and down the tube into the drip pan. Look to see,
      after you have been defrosting for say 15 minutes, to see if you are
      getting lots of water to now thaw and drain into the drip pan below. If
      you see such evidence, then you will know that this was what your
      trouble was all about.

    Is the refrigerator still trying to cool as in is the motor still humming? Since many things go wrong, you are going to have to check to see what is still working so that we can narrow it down. This is the first thing that you need to check. Turn it on the coldest setting and see if the motor/pump is still running. Please let me know what you find

      most likely the fan either stopped cooling the compressor motor or the relay stopped working but you will have to check all of the parts to know for sure, so please let me know what you find.

    Samsung double door refrigerator/freezer is not holding the tempature in the refrigerator. When you attempt to reset the temperature and press "power cool" nothing... temp remains around 56 The freezer...

    I just had (have?) this same problem. I called out the repair man and in the end he suggested that I buy a new fridge because of all the problems reported with my model (RS2555SL) on the internet. Anyway, after a while I heard what sounded like a fan trying to spin on the fridge side. I unplugged the unit, removed the inside back panel on the fridge side. The entire coils and the fan had iced over. I removed all the ice, plugged the unit back in and it is now working. I will still replace this unit because I probably only corrected the symptom but the problem remains.

    Control panel not working Samsung refrigerator model rs2533sw. Not cooling.

    I have a samsung refrigertor rs2555sl and my control panel stopped working after I turned the power off to the house (to install a light fixture elsewhere). There was one green light blinking on the refrigerator temp display.

    Hold down the "power freeze" and "power cool" buttons at the same time for at least 8 seconds. This is a self diagnostic program. A number should appear on the refrigerator temp display (1-9) will hold for 30 seconds and then the panel should function again.

    In my case the number that appeared was "3" which can indicate a multitude of things including a short circuit or power outage (which was it was for me).

    Hope this helps!
