We have a whirlpool side beside fridge model number ED5JHGXR000, it is freezing up on the fridge side. We have to take a hair dryer about every six months and thaw vent system out. We can tell when it istarting to freeze up when the veg/meat drawer starts freezing up first. If any one can tell me how to fix the problem it would be great, about to give up and get new fridge and this one is only 4 years old.

You should have a digital set point for freezer and refrigerator temps-warmer/colder or 1-10. Where are they set now? Try lowering the number for the refrigerator.
