Tip: Most self-defrosting household refrigerators that loose part or all of their cooling in the freezer or fridge are having problems with the self-defrost system. Three components to check: defrost timer; defrost heater elements (esp. on side x side units); and evaporator fan. All cold air is normally produced in the freezer, then circulated via evaporator fan to the refrigerator section. About every 12 hrs. a defrost timer turns off the compressor, and turns on the defrost elements to melt the frost from the evaporator coils. This normally takes about 20 minutes to complete, then the timer turns off the heaters, and restores normal cooling operations. If the cycle does not complete properly, the coils will "ice up", restricting proper air circulation through the freezer and refrigerator sections. Worse yet is if timer sticks in defrost mode (rare), it will turn the freezer into an oven. If the defrost system seems to be working normally, then you should check the condensing coils for excess dirt, and vacuum &/or bush the dirt and lint out to restore proper head disipation. It's recommended that you vacuum out a condensor that's located on the bottom of the unit once a year. You should also check the condensor fan (if present) for proper operation. If the condensor fan fails, heat can not be properly released from the condensor, and will cause the refrigerator to 'run all the time' yet not cool efficiently. There are many things to check on modern frost-free refrigerators, before turning to the actual sealed refrigeration system and compressor unit.

Most refrigerators have resistance heaters around the door seals to keep down condensate and "sweating "during the summer. Check your model to see if there is a manual moisture control switch inside.You would then be able to turn them off in winter.If there is no switch, then the fridge automatically sets the heaters and you're good to go.
hope this helped
