Hello, I'm French and I need your advice about a problem on my refrigerator. The fresh food side begin to be freeze in the low of section.
The damper opening when I increase temperature on thermostat of freezer and so on thermostat of fresh food section, but I don't understand why when the compressor is stopped and I increase thermostat of freezer, the damper begin opening when normally, it should to be closed.
Answer Hello Lionel,
Think of the unit like this: When the unit is sitting idle, since cold air is heavier than warm air, the cold air migrates to the bottom of the unit. The air return at the bottom behind the shelves in the fresh food section goes directly into the freezer section as an open return port. If the unit sits too long without the fans running, the cold air will "backflow" back into the bottom of the fresh food section, freezing everything in the drawers. For this reason, the controls seem to be backwards when correcting this issue. To correct the issue, the fresh food section has to be set Colder and the freezer side has to be set warmer. This corrects the issue by calling for temperature more often and kicking the fans on more often, stirring the air in the unit and preventing the coldest air from settling to the bottom. As far as the damper actuating, every time the electronic control sees a control setting change, it will activate the damper and, even though it makes no sense, the programming will work the damper door.
