Samsung RS21DCNS side by side fridge freezer
« on: January 26, 2012, 08:04:30 AM »
Hello everyone,

I wonder if anyone is able to help me with a problem that I am having with the above-mentioned appliance?

I am not getting voltage to the condenser fan motor from the main board, however, the compressor runs.  I checked the 3 wires from the main board to the fan motor for continuity and they were all fine. Then I took out the main board and fitted it to a same model fridge and the condenser fan motor on that fridge ran - it seems that the board is fine.   It appears that something is holding out the main board from sending voltage to the condenser fan motor, but I do not know what it could be.

Any suggestions?

In fact I have two of these with the exact same problem!

Best regards

I'm new here, just a silly question. Did you already check if the fan itself working?

Hope that help,

Hello,

Yes I checked the fan on a working model and it runs fine.  The problem is that I am not getting supply voltage from the main board to the condenser fan motor wiring harness.

I found more information about the c-fan for you.

C-Fan have the delay function, just to make sure you know about this.

Above 66℉  Condenser-Fan is ON as soon as the compressor is on.
61℉ ~ 65℉  Condenser-Fan is ON with 5 minutes delay from the compressor on.
Below 60℉  Condenser-Fan is OFF regardless of the compressor operation.


As I understand in the working condition, if you check the S/BLU  line with GRY line you should read 10Volts or 8.3Volts.

Hope that help,

Hi Ting,

Thanks for the information.  I know for sure that the temperature in my workshop is below 60 (around 45 at this time of year).  That may be the problem.  The same model that I tested the main board on is in my house which is above 66.  It may be, my dear friend, that you have solved my problem! In which case, thank you very much and may God bless you with ten sons!
