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:
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

It is important to determine the voltage and frequency of the power supply in the country where you want to use your air compressor. In Africa, most countries use 220-240V at 50Hz as the standard voltage and frequency.
If your compressor is designed for use in the United States, it may be rated for 110V at 60Hz, which means it is not compatible with the power supply in Africa without a voltage converter or transformer. Using a device that is not designed for the local power supply can damage the device and potentially cause safety hazards.
To determine if your tank air compressor is compatible with the power supply in Africa, you should check the specifications on the device or its manual to see if it can operate at 220-240V at 50Hz. If it is not rated for this voltage and frequency, you will need to use a voltage converter or transformer to adjust the voltage and frequency to match the requirements of the compressor.
You need a frequency converter - however, these are not cheap since they are intended for industrial applications - usually rated to drive motors. Depending on the device that you are driving, you might be able to adapt it for a DC input and convert the generator output to DC, or modify it to accept a 60 Hz input.

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.
Colinchee, this sounds like a rather complicated electrical engineering issue. Why not buy a coffee grinder in the UK design and rated for your power? It might even be cheaper and the guarantee will cover design flaws. Regards.
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.
You will need AC to AC converter that will accomodate US to UK mains. Look for power requirements of your amp on name plate and match with available converters online. Make sure power line frequencies match in/out requiremnts
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.
Hi,
Your idea is basically sound and should work as long as the UPS originally is designed to produce 240V 60Hz and has its own built in timebase. The reason is that the input as long as the voltage matches makes no difference (50 or 60 Hz). By design, the UPS converts the input voltage to DC to charge the internal battery. The battery then powers an electronic circuitry that produces the 240V 60Hz. The input is then isolated from the output in terms of frequency. This is a common design, however, there are some (not many) that uses for its local oscillation sampling from the source and therefore will replicate the input frequency to its output, but very rare; it's better that you know they exist.
Hope this be of some help/idea. Post back how things turn up or should you need further information.
Good luck and kind regards.
P.S.
The only problem with 50 and 60 Hz is heat buildup which is tolerable and still within safe parameters. The only time the 50/60 HZ makes a big difference is when motors are used, timers such as in the early designs of microwave ovens, washing machines, etc., pumps and other highly inductive consumers. Most electronic devices converts the AC input to DC and therefore the frequency has negligible effect. Of course others may see it differently.
