Question about Samsung RS2630SH Side by Side Refrigerator

SBS Refrigerator mains frequency 50/60Hz

I have just bought a Samsung side by side refrigerator from a country running 240V 50Hz supply (Bahrain), the unit was immediately shipped and installed in a country running 220v 60Hz (Saudi Arabia). The problem is that since new the refrigerator side has continued to freeze up after about a week. The freezer appears to work fine. I have called the Samsung 'technicians' out three times and they have replaced the thermostat, checked the rest of the unit and assured me that all is well. When I pressed them for a solution to the problem on their third visit, they opted for the compressor being the cause of the problem. It is a 50Hz and not 60Hz compressor. Is this the cause of the problem? And if so by replacing the compressor with a 60Hz one will this fix the problem. I have replaced the heater with a local 220V one, as the original one did not seem to heat when connected to 220v, but then the internal rear of the fridge covering the cooling unit (heat exchanger?) unit just seemed to get hot and the fridge still froze over. I have ordered a new Printed Circuit Card at the lower rear in the hope that this might fix the problem but am still waiting for the card?.. I have trawled the net for some definitive information, as surely in this global village frequency problems must not be unique to me. Any help appreciated.

The problem was the main Printed Circuit Board was defective.

After waiting 8 weeks for a replacement from Samsung, it was repalced along with a new original heater all is well!

The best the local Samsung 'trained' technicians offered was 50% reduction on the price of a 60Hz Compressor!

Thanks for your help and advice

This problem seems to be a common one and in my findings it was a faulty thirmister giving the wrong info back to the main board saying the fridge is not cold enough try that first it is the cheaper option good luck

Samsung filter will not rotate and lock. I have tried 2 type filters and recently bought an OEM filter and it wont work either. I am about ready to give up.

Not sure this article and its suggestions will help, but basically it says to shut off the water supply to the refrigerator and then operate the water dispense lever to relieve pressure that could be preventing the filter from installing.

I have a ge sbs model pcp23shmffbs. the condenser fan motor is running slow, but turning freely. the fan motor is rated at 11.3 volts dc and supply to fan motor is only 6.7 volts. is the condenser fan...

If the motor is running, but running slowly, you will need to replace the motor. If there was a problem with the PCB, (control board) the motor would not run at all and you would see other problems with the refrigerator.
Here is a link to the motor.

99% chance that the surge blew the power supply board. If it is a French door, bottom freezer model with ice and water through the left hand top door, it may have taken out the motherboard too. Samsung uses at least two boards, one main motherboard and a power supply board that powers the main.

The fan should be a standard 12v DC computer style fan , test that you are getting voltage to the fan connector . You should also be able to get the fan to run by connecting it to a suitable supply . Once you have eliminated the possibility of fan failure then it gets more involved.

Water Dispencer switch is very slow to close off.

The problem may be in the electric valve in back of the refrigerator that supplies the water to the door dispenser. A small particle maybe lodged on the seat of the valve causing the slow closing and dripping. Replacing the water valve assembly may solve your problem. I would also recommend installing an in line water filter before the entrance to the valve.

Fridge frequency

AC voltage (alternating current) rapidly changes from +ve to -ve and back again. The frequency with which it changes each second is measured in Hertz (Hz for short).

The speed of an AC motor (which is what you have in the fridge's compressor) is dictated by the AC frequency.

What this means is that if you connect a motor designed for a 60Hz supply to a 50Hz supply (which is what you'll be doing) it will only run at 80% of its intended speed.

Whereas running it faster than intended might cause damage to the motor, running it slower is highly unlikely to.

The only real effect that you will see is that the fridge will take longer to initially get cold and the compressor may run for longer periods to maintain the temperature. There is a slim chance that the fridge may also struggle to achieve the coldest setting.

Changing the compressor is not a simple job and needs to be done by an expert as it involves re-gassing the system.

Personally, I would just use it as it is and see how you get on.

Hope this helps,
