Default Samsung Fridge Not cooling

Hi,

I have a Samsung French Door Fridge, with bottom Freezer.

Recently it has been acting up, It would cool hit the temps, then it was almost like the thermometer wouldn't start reading the tempature again. I would notice the fridge was warm, Unplug, then plug back in and hit the button to see the Temp and it was up to 52, even though just before I unplugged it, it read 34.

Then the Fridge would cool again, and I would repeat the same cycle.

I placed a call into Samsung (the fridge sadly is out of warranty, just, for non compressor/evaporator issues) and they sent a guy out. He tried replacing the fan, saying that it was not cooling the compressor. But apparently this fridge needs a specific fan whereas most fans are interchangable, and that did not seem to help. He then decided it was probably the motherboard that was causing the issue. So we got a new one ordered and that was just replaced today, but the fridge will not cool. He said that the fan will turn on for 4 seconds then turn off then turn on for 4 seconds and turn off. So the thinks because the fan he put in was not specific to this fridge that might be the problem. So now we are having the fan replaced to see if it fixes it, if it doesn't he says the wires from the motherboard must be toast, and we will have to get a new fridge.

Does this seem right? or does anyone have any other thoughts? My initial thoughts was that it had something to do with the thermometer, is there a way to test the thermometer?

Any help would be greatly appreciated.

Chris

Hi,

1) Try a different company/servicer!

2) Can't check the temps by unplugging and plugging it in....won't show correctly.

3) No model# posted but yours -sounds- eletronic controled = no "real" temp thermostat.

Hi Jeff,

Thanks for the reply for #1, This is a samsung authorized servicer who samsung sent out for us. Going to find another servicer will just add on to the 400$ that has been spent already, Is there something that the servicer is doing wrong that would make you say this? We have been without a fridge/freezer for a week waiting for another servicer to come out, would suck for that.

#2 What makes you say the temps wont show correctly, When the issue was occurring I put my instant read thermometer in there and it was reading the same temperature as the readout said on the display.

#3 the model number is RF267ABRS/XAA Yes it is a digital display. What do you mean no real temp thermo? How does it tell the current temp then?

Tried and probably are normally not what appliance techs do....test/diagnose is better and the odd time we may take an "educated guess".

Can't unplug to check temps or settings. Acual temp and set temp are different things.

There is not a temp/cold control like older refrigerators....has thermistors that change resistance to tell the board what is or is not happening inside, they turn on or off nothing....the board does that.

Condensor fan motor appears to be readily available...


Condenser fan motor Manufacturer Number DA31-00020H

Thanks Jeff,

I double checked with Samsun Support and they said that pressing the Fridge/Freezer Temp set button once, it will blink and then show the current temp inside the fridge. (Support said there is a sensor inside the fridge to read the current temp) I also thought that I read this in the user manual, but maybe this is incorrect.

In your opinion does it seem like it is the condenser fan that is causing the problem?

Thanks,

Chris

*If* the condensor fan motor was not running at the time of the service call....that definetly would have been a good place to start...the condensor fan motor helps to remove the heat from the hot condensor tubing and from the compressor. The compressor can over heat and shut off on it's built in safety device.

Pressing the button(s) is one thing, removing power is another.

Jeff,

I think you are misunderstanding me with the current temp. I wasn't unplugging to get a read out. What am trying to convey is that it seems like the Internal temp was not being read correctly. So I would wake up in the morning, press the button to see the internal temp and it would read -2 for the freezer and 34 for the Fridge. My instant read thermometer was reading the fridge as 52 degrees. If I then unplugged the fridge, waited a few seconds, then plugged it back in, then press the button to read the internal temperature, It was reading 52 for the fridge and 21 for the freezer. A few minutes later the fridge would start cooling again until it hit the desired temps (-2 and 34) and then the cycle would start over again.

This is why I am questioning if it really is the fan, I don't think tech who we have out her, or the Samsung techs are understanding this point. Why would the fan make the temp readout incorrect? I could understand the motherboard, but that has been replaced.

Chris

I understand what you are saying....but it still doesn't tell us anything. Needs to be checked when this is occuring rather than after unplugging it.....could have been in a defrost cycle and unplugging it stopped that, etc.

Hopefully the new tech/company can catch it at the spot where you are concerned and check it out from there

Wozer - If possible, can you let me know what ended up being the culprit? I have a different model fridge than you do, but the symptoms are identical as what you described so am interested in what the problem was.

Yuchai,

They tried replacing the Motherboard as well as the Fan, neither worked, we ended up having an extended warranty with Lowes and used that to get a new fridge.

Sorry I cant help any more than that.

Chris
