Question about Samsung Refrigerators

1 Answer

My refrigerator (RB1855) runs excessively long. Down time 15 minutes and run time 20 minutes. Noise comes out from the compressor. Even raiseed the temp setting (-18 to 17 and 3 to 4) when it is running but the compressor still does not stop in quite minutes (till now). evaporator fan was replaced a couple of months ago and the fridge was running ok.

    RB1855SW. Now the fridge runs even longer (maybe 1 hr). Noisy sounds like from the stuff aside (on) the compressor bowl.

    Two months ago, almost the same thing happened on this fridge. Difference is, there was ice in the fridge and water drained into the fruits box and bottom of the fridge room when the ice was defrosted. Later, the fridge could not be cooled (shown 9C, but I measured with my thermo, it was almost room temperature. I replaced a F-room thermal fuse (wrap at the evaporator tube -- hope I'm correct, they are all located a the back of the fridge room)and later fridge fan motor (on the cover panel of the evaporator area). The machine then worked fine for one more month.

    This time, the temperature is ok for both rooms up till now (three or four days when we first noticed the problem). At the beginning of each running circle, the noise is on and off (about 5 seconds each), and then on for longer and longer. Some times, when moved the fridge, the noise stops. Compressor has been waorking all the time no matter noise or not.

    Dear Sea Breeze,
    Received your comments and email, thanks a lot.

    The parts I replaced one more month ago are:

    DA47-00095E(or D?) fridge thermo fuse and,
    DA31-00003N fridge fan motor.

    I guess there is an error on the Part List web site http://www.pcappliancerepair.com/model-d...
    for the part number of fridge thermo fuse. The part list shows the part number for the freezer thermo fuse and fridge thermo fuse are the same, but should they not be the same (DA47-00095D for the fridge one)?

    I did something since last night and I'd like to describe it here.

    Last night the machine kept running with excessive noise and temp shown were -18C and 3C as set.
    12:30am, unplugged;
    8:30am temp -5C and 9C (10C per myown thermo);
    8:30am plugged, no noise;
    Temp stayed -5C and 9C till 8:37am;
    8:38am, temp -6C & 9C;
    8:54am, temp -12C and 6C;
    9:15am, temp -15C and 3C, start noise (2 seconds on and 5 to 10sec off);
    9:32am, -18C and 3C (setting), noise 3s to 7s on and 2 to 5s off;
    9:33am, moved and opened the back machine cover. noise stoped 2 seconds after the cover open.
    9:34am, temp -19C and 3C;
    9:38am, temp -20C, short noise for 2 seconds, unplugged.

    Other observations: looks the noise is from either the O/L protector DA34-10003D, or PTC Relay.
    Compressor temp felt high. Finger touch could not stay on more than 2 seconds.

    Question 1: Sounds the compresser operating normally. Is the temp raise(negative) speed in the normal range?
    Q2: Does PTC relay make noise due to high compressor temp? Is the compressor temp too high due to long time operation?
    Q3: Where is the temp control (thermostat)? This is my first time to see the temp shown lower than setting (-18C).
    Thanks and best regards,
    Mike

    What you see on the tube is not ice. The fridge was just started after one day's shutdown and the freezer temperature was 10C.
    I took another shot just a few minute ago and the tube looks the same. The fridge is unplugged since last night and is not running now.
    There are two evaporators for this fridge -- freezer one and fridge one. Never opened the bottom one (freezer). There used to be frost problem two months ago on the fridge evaporator as I explained before. I replaced the thermo fuse and evaporator fan motor and seems the problem was resolved.

  • registeredau Jul 16, 2009

    I agree there may be a refrigerant issue.
    Not hear any noise of air in the recirculation. I'm supposed to be good at water hammer or air noise in pumping.
    One thing still do not get answer: compressor runs for quite a while after the temp settings were reached and restarts just after a short interval (30 minutes or so). I think door seal's good enough.
    Regards, Mike

    OK, Then we need to look at the model number suffix for example yours is listed as RB1855 and when you go to my sites http://appliancepartseast.blogspot.com/



    or SITE 1=> http://appliancepartseast.blogspot.com/

    click on Matag Service manuals, that will take you to the home page of Service Matters. Left top click on model numbers and only enter RB1 this will take you to a list of models simular to yours. Look for the suffix that is like your listed on that page. You should find the complete model numbers listed in places in photo below, Thanks, Sea Breeze

    Do you have an amperage meter? Or a AMP Probe?
    We need to check the amperage at the compressor while running and touch top of compressor to see if it feels too hot to touch. We also need to get readings and temps and times like you listed. My concern is there may be either a electronic problem coming from the thermostat control board or if mechanical thermostat. Also because the compressor seems to stop and start will cause temps to fluctuate like your explanation. Sea Breeze

    Do you have a digital camera so you can send me photos of your control panel inside the fresh food compartment. and a few of the refrigerator itself. I know that over time the model numbers fade especially if they are placed on the inside of refrigerator. Below are the 5 models similar to yours...Sea Breeze

    Mike, A noisy compressor is usually a sound of a worn out compressor. When a compressor is too hot to touch the cold freon is not cooling it sufficiently. The noise problem disturbs me because if I told you to put a boost capacitor on there it would maybe help a day or maybe 3 or 4 years. How old is your refrigerator? The problem also could be the start capacitor or the start relay. I asked a while back if you could get an amp probe. Can you find someone to check the amperage at the compressor. If the compressor continues to overheat it will damage the internal overload. Remember, start relay, start capacitor or worn out compressor is what I have come to. Let me know if you want the SUPCO Item # RCO410 3 n'1 start package. Or if you want to replace the compressor? Or do you want to confirm the compressor is faulty?

  • John Tripp
    John Tripp Jul 13, 2009

    Just thought about the control board has a relay to tell the compressor to start is defective it also will cause the compressor to over heat. But the noisy compressor is most likely a worn out and out of balance compressor motor inside the sealed hermetic case.

    Mike, Is that ice I see all the way back to the compressor? If you have a freon leak in the evaporator the the suction has pulled air into the sealed part of your system. That will clog the capillary tub with ice and cause the compressor to struggle making the noise. You should only have a little sweat on that big line for the time frame you say it's cycling. Now we need to look at the evaporator or check to see what it looks like after running for a while.

    Soon as you get a chance to see the evaporator coil take a photo of that also please. I think sometimes the saying a picture is worth a thousand words is true. Sea Breeze

    If the compressor is too hot to touch and the refrigerator and freezer are not keeping the temperaturs needed to protect the food we have a problem. the compressor is running hot all the time and working all the time for nothing. If the fans are working on yours and I believe you have three fans.The refrigerator was buil;t with the defrost heaters woven into the evaporator coils and cannot be replaced unless the coil and the heaters come out together. I don't understand whose idea that was but be willing to bet he or she no longer works for Samsung. The lines on the compressor during normal operation the big line with the accumulator reciever just before going back into comopressor should feel cold and the discharge line going out to the condensor should be very hot. The compressor should not be making the noise its making or taking so long to cool down. The air comming from under the refrigerator should be very warm and the refrigerator with the 2 evaporators coils should be very effective. You either have lost freon or the evoporators are frosting over. The compressor is struggling because it needs that cold return to it to help keep it cool. You need to find someone to check the refrigerant charge. There is a self piericing valve that can be put onto the suction line. With the freezer at its coldest temperature the suction line should measure about - 4 lbs. inches of mercury. You have a leak poor air circulation or a defective compressor. The compressor runs too much and too hot for something that I would not call less than severe wrong with the refrigerator. This is not going to be an easy fix. Try to find someone that knows refrigerators and won't charge you too much. I would like to fix it but you probally live in Vancouver BC I have all the tools to fix it here. But with what you have told me I know it needs work. Please let me know what you find out. This is not an electronic problem, yet the manual show you how to do diagnostics. I'm sorry but you are going to have someone with hands on service. Thanks, Sea Breeze

It keeps going through a start up process (clicking and the fan come on then off quickly) at first staying steady then getting longer in the start up process.


Hi David, thank you for your inquiry. I understand that your Frigidaire Refrigerator is cycling on and off more than you expected. Todays newer refrigerator's have to meet Dept of Energy (DOE) specifications for energy savings. Typically the fan and compressor runs to get the fresh food temp down to 34*, the compressor shuts off and the fan runs for thirty more minutes and shuts down. The fan will repeatedly cycle on and off to keep the temp down as close to 34*. Once the temp in the fresh food hits 40* for more than two minutes the compressor cycles back on again. This will cause the temps in the fresh food to dwell between 35-40 and in the freezer section between 8-15. Hope this helps! -JK

Bottom freezer stopped working, then started working. Would this be a problem with the thermostat or blower fan? During this period refrigerator half had no problems.


Hello Steve:

My name is Peter. I am a retired field service refrigeration technician.
You do not have a problem. It sounds like your refrigerator is running normally.
Your compressor and fans will run based on the cooling demands set by you on your temperature settings. Once the temperature has been reached your compressor or fans will stop running.
If your compressor is running all of the time then you have a cooling problem.
You refrigerator will also shut down about every 8-10 hours for about 15-20 minutes. This is when your refrigerator goes into the defrost mode. Your refrigerator shuts down and the heater around the cooling coil turns on to defrost the cooling coil. This is where the term; "Frost Free", comes from.

My GE Profile Refrigerator (model PDS20MBSBB) is making a clicking noise. The thermostat display turns off while this happens. When it comes back on the fridge gets really cold and then slowly gets


needs new control board wr55x10942. condensing fan not running or running slow. it get to hot then the compressor relay cut off compressor to protect it once cooled down enough it starts back running.

Refrigerator wont run. Clicking noise coming from main board preceded by a short humming noise every several seconds. Unplug for 30 minutes then plug back in and compressor starts up after several clicks...


Hello,
That condenser fan motor needs to be replaced. You and doing the right thing as far as using a seperate fan to keep compressor cool,buy replacing the fan the compressor will run cooler and click off by being too hot as you have heard/seen.

Find your model number and call your local appliance parts store and see if they have a CONDERSER FAN MOTOR in stock

Fridge sounds like my air compressor in the garage when it runs. Will run for about 25 minutes making this noise then stop for about 15 minutes. Suspect the compressor is going or low on coolant.


Hi,

It may be the compressor but I suspect that it is the fan making the noise...

Here is a tip that I wrote about refrigerators and the fan noise that they develop sometimes...

Refrigerator and freezer are not cold. Makes a clicking noise.


Check the starter relay which is next to the compressor behind the cardboard cover on the back. It may be burnt and can't start the compressor. It's on or near the compressor. If it's bad it will rattle when you shake it and may appear burnt.

Check the compressor.
Unplug for 15-20 min. plug it back in and listen for the compressor to start. You will have to be behind the ref to listen and make sure you hear the compressor start and not just a fan running. If you hear a clicking noise then the compressor relay is bad.

Fridge not cooling compressor works intermitently


If the compressor starts and runs for a few seconds it could be the relay. Or it could be the compressor itself has failed. When a compressor starts and runs for a short period it is possible that the relay contacts are arced together which would have both the start and run winding in the motor engaged at the same time for more than 3 seconds. This would result in the compressor tripping out on the thermal overload. It depends on what type of relay your compressor has. If it is a thermal relay, unplugging the refrigerator for about 15 minutes would allow the relay to cool off and reset.

Refrigerator not cooling


Did you lay this refrigerator down on its side or back when you were moving it? Is there a chance one of the tubing lines in the rear or under the refrigerator got damaged and allowed the refrigerant to leak out? If yes to either of the questions you will need a service technician to do a sealed system repair.
There is probably a fan under the refrigerator near the compressor that should be running any time the compressor is running. If it is not running when the compressor is running the system will not work well.
