Why is the lettuce freezing?
In one sentence
Either more cold air is reaching the fresh-food side than the cabinet ever asked for, or the control is being told that compartment is warmer than it truly is. — Viking Repair Denver Pros, (720) 903-2603
What it usually turns out to be
-
The damper is stuck open
Cold is made in one place and shared between two compartments. On cabinets that meter the share with an air damper, a flap that no longer closes leaves the way permanently open, and whatever sits nearest the vent takes the brunt of it. Salad leaves, milk and anything else mostly made of water give up first.
-
The sensor is reading high
A control cannot feel cold; it reads a temperature sensor and believes what it is told. A thermistor that has drifted upward reports a compartment warmer than the one you are standing in front of, so cooling keeps arriving in a space that was already cold enough. Frozen food on a display that looks perfectly reasonable is the classic shape of this one.
-
The board is acting on good information badly
Less often, the reading gets through correctly and the main control board still runs cooling past the point it should, or holds open what should have shut. This one is reached by elimination rather than by inspection: the sensor and the damper are proved sound first, and only then is the board named.
What that means for your kitchen
Start with the two checks that cost nothing. Read what the control is genuinely set to, because a knock while somebody unloads the shopping moves it more often than anyone admits, and then look at where the food that froze was actually sitting. If the setting is sensible and the drawer is nowhere near a vent, the fault is inside the cabinet and deserves a proper diagnosis rather than another week of shuffling shelves around.
Follow-up questions
Why does it only freeze the food at the back?
Because that is where the cold air arrives. Anything standing directly in front of a vent gets the coldest air in the compartment, and leaves and liquids surrender at the smallest excess. If moving the salad forward by a hand's width settles it, nothing has failed and nothing needs replacing.
Can I just turn the fridge up a notch?
You can, and it is worth a day of trying. What it will not do is cure a flap that has stopped closing or a sensor that has walked, because both of those overrule whatever you set.
