Francisco H. for Model Number GSG20IBMCFWW; N0 ZA212175; 220-240V; 50HZ

I am looking for the main control board for the model above. I live in Singapore and the refrigerator works on 220-240 volts. The NO I included after the Model Number is stated on the back if the refrigerator, next to the model number. The picture of the location of the electronic components of this site is a bit different from the picture of my board. However, the location of the connectors appear to be the same. I wonder if the control board you recommend on your website will work. Many thanks, Francisco.
