Will not make ice, freezer temp is high, can not control the temp

Make sure the internal vent is not blocked with ice.

If it has auto defrost the temp shown will go really high but only for a short while. It sounds like the defrost timer may be faulty if it is defrosting products

if the freezer is operating ok,then the refrige side isnt out of gas,its the damper vent door between the freezer and refrige thats not opening to let cold air into fridge from freezer,sometimes they stick shut due to ice from condensation on this door,remove grille cover on damper door and check this,if iced up defrost it with a hair dryer,then change temp selector and make sure door then moves with temp change

in the fridge compartment check behind the control panel where the light bulbs are remove this cover and make sure the damper vent door opens and closes when adjusted with the fridge control sometimes they ice up from condensation and freeze in one position and this may let too much cold air in from the freezer for too long,otherwise it also could be a defective electronic control board in this same area

check the damper door located between the freezer and refrigerator compartments(this lets in the cold air from the freezer) and make sure it opens and closes with your temp adjustment in the refrigerator compartment,sometimes they ice-up and are frozen in one position then take a hair dryer and defrost the door

You can use a hairdryer on the frozen parts.
The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp ..

I had the same problem and I discovered it was the defrost element that was shorted out which keeps the ice from building up located behind the back freezer wall.

Is the freezer cold enough to make ice maker operate. 10 degrees or less.

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

This sounds like the Maytag bottom mount that has a High Voltage Control Board problem. Does this have the freezer/fridge temp. display/controls on the left hand fridge door? Whats the model number and on the manufacture tag does it something on it like Code:0304 maybe? Let me know I may have an answer I do work on these for a living.
