Inspect the vents to determine what is preventing the free flow of air. The other day I wrote about how our refrigerator was warm (50 degrees) yet our freezer was cold (0 degrees). Cool air never reaches the center items and they cannot be properly chilled. They suffer from daily wear-and-tear just like other home appliances. 3) Heat will continue to flow from the warmer object to the colder object until their temperatures are equal. More warm air = more cooling required = higher fridge juice consumption = lighter wallet. This could disrupt the air flow and cause temperature issues.

It seems to cool and freeze ok.....but we've noticed smaller ice cubes....and a diminshed water flow from the dispenser. This is because the Freon line is sucking air in to compress it. Straighten the water source line to restore adequate water flow and pressure. Check the pressure gauge by … This video provides step-by-step repair instructions for replacing the air damper control assembly on a Whirlpool refrigerator. Due to this the circulating fan is unable to draw air over the frosted coils. However, refrigerators are not indestructible. Not every refrigerator installation will have one.
