Refrigerator food freezing even when on lowest setting
There is one of three reasons why your fridge section is freezing food.
You didnt mention whether you had a side by side or freezer on top or
bottom model, so the following checks may not apply to your unit.
One reason food might be freezing is your cold control has failed, and
will not turn the unit off when the physical temps are correct. When
this occurrs food normally freezes throughout fridge section, top,
bottom, middle, front and back.
BOTH controls, though you may only have one, should be at the middle
setting. Adjust your controls, place a plastic cup of water at the top,
the middle, and bottom shelf of your fridge. Check all three AFTER 24
hours. if all three are ice, you COULD have a bad cold control.
It is possible you might also have a door damper that is stuck open. A
door damper is a swinging or sliding door that opens / closes either
when temp control settings are adjusted, or on some fridges, when either
door is opened, the damper closes. Please note, door dampers are
USUALLY only present on side by side refrigerators. They can have a
motor, or thermostat open the door automatically,which can break, and
others will simply have a lever of some sort, which usually wont.
If after 24 hours, only the middle and bottom cups are ice, your
evaporator fan motor, in the freezer, is likely not operating. Not
knowing the BRAND you own, it could be the motor itself, a thermostat
located on the evaporator, your defrost heater, or a main computer
control board that controls the fan motor.
Sorry I cant be as specific as id like, but i had to cover all possible bases
