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,
