The freezer is maintaining its temperature of -22 degrees but the fridge compartment is not cooling. The fan is working when the door closes and the light goes out.

After having read lots of forums I know it is one of the sensors next to the fan in the freezer compartment but which one? There is a yellow, green and white section and then another white section which is separate to the first three.

Could someone please help...
