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.

Re: SBS Refrigerator mains frequency 50/60Hz
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

Sell it as a second hand tv,get,what $ u get.Sorry,if ur tv is not a Region Free tv Systems.It,will run only on NTSC signal frequencies,will not run on PAL signal frequencies.Ausi as u know,run on PAL and 240V 50Hz.Will work with a step-up tranformer,but if only,if ur tv is a Region free tv Systems.
Check the unit for a sticker stating it's electrical approval numbers. There should be the voltage and cycles required. There could well be a switch of some description near this sticker Saying 120-240 with an arrow showing which way to put the switch to change the voltage. This usually involves removing a plate of some description to stop someone changing it by mistake. Don't forget the cycles as well. The UK uses 50hz or 50 cycles whilst the USA uses 60 cycles. Using the wrong one could burn the power supply out and even cause a fire. Many smaller electrical items are self seeking when it comes to power supplies but large components such as TVs and HiFi units are usually set.
If the sticker says 240 volts 50 hz then thats for the UK
If it has 120 volts 60 hz as well then it's possible to use in the US. Luckily it has a dual power supply built in. The chances of this is rather rare so you could have a boat anchor instead of a HiFi
Whatever you do DON'T just chabge the plug and try it out. There'll be smoke for sure.
If you are unsure get it checked by an electrician.
One way out would be to buy a transformer which changes the 120 volts to 240 volts but you will still have the cycles to worry about. So unless the cycles are changeable you can't use the hifi in the US.
Sorry for the bad news If it's not too large it's possible to recover some money by selling in on Ebay in The UK or Australia or any other country using 240/50hz
it would be simpler and cheaper to get a new dryer
most of the world uses a single phase 240v 50hz system, your dryer is designed to run on a 2phase 120v 90degree system.
the common statement that high voltage items like dryers use 220-240v is not strictly true, instead they run off both 120v phases of the 2phase system.
A transformer to produce a 2phase 90degree 120v 20A secondary from a 240v single phase source is expensive and very large.
It would be cheaper by far, to sell the dryer, and replace it with the equivalent model built for 240v single phase, than to buy the transformer and ship the dryer.
Extensive analysis revealed this unit to be for 120V 60Hz regions. If you use it in a region where the mains supply is 220/240V 50Hz then it won't work. In addition, the PSU will overheat, with possible damage to other modules.
One possible solution is a 120V 60Hz inverter, else Samsung may be able to provide the correct PSU for 220/240V.
THIS document has a lot of info about the wiring for the unit you have. starting at page 6
I am, however confused about the voltage requirements as reference to 12/240VAC with a note to check the "rating" plate
If your unit is marked as 240VAC then it should be a simple task for an electrician to wire up the power. The instructions/details are in the manual (link provided) to connect it up as a standard 3 wire system used in the UK
The issue you have is that the motor may not like running on 50hz and may run HOT. It will also run slower on the lower frequency.
The specs on the website are as follows:-
Electrical Requirements 30 Ampere, 120/240 Volts, 60 Hertz (1/second). AC-ONLY. USE COPPER WIRE ONLY. A FOUR-WIRE OR THREE-WIRE, SINGLE PHASE ELECTRICAL SUPPLY REQUIRED. A TIME-DELAY FUSE OR CIRCUIT BREAKER AND SEPARATE CIRCUIT IS RECOMMENDED
It may be worth getting all details off the rating plate and posting back here...
My suggestion is that you consult a qualified electrician before attempting to connect the unit to the power
first of all what area are you living in in Philippines 220v as there is voltage rating differences in Dubai
Dominican Republic 120v
64 other voltages. 50Hz
the board will be set for country of origin, this could mean the power board can be getting more than the ratings need, there will be voltage regulating chips on the power board, main voltage can handed depending on the chip installed up to 600 volts but the other parts cannot handle low voltage or high voltage, this could mean a spike in voltage may not blow but it may weaken the voltage out. i.e capacitors- voltage regulators or even diodes. these have to be checked.
This trimmer is only made to be used with 110V, we do not have this model in 240V. There is no way to stop the noise. If you would like to purchase a unit made for 240V please call 1-800-558-9441 and speak with one of the Andis customer service reps.
