Question about Maytag Refrigerators
Sounds to me like a intermittent defrost timer not advancing.
It is located behind the plastic cover over the controls.
Remove the switch knobs, then remove the cover. The defrost timer access is on the right hand side. You can turn it with a flat blade screwdriver. Turn SLOWLY clockwise until the compressor kicks OFF. That is when the defrost heater is energized.
After a few minutes you may be able to hear a sizzling sound from the freezer. That would be defrost water hitting the defrost heater.
If it does the defrost at this point, replace the timer. about $30.00

Possible of 3 reasons.
1) Defrost bimetal is open and not allowing power to heater element in evaporator coil in freezer.
2) Defrost timer is not going into defrost, motor stopped moving.
3) Evaprator fan motor is not rotating. Possible motor.
First check for frost in the back panel of the freezer section.
if there is frost and the fan is operating, would suggest manually putting unit into defrost, depending on particular model. may be a switch you can move with a standard screw driver to get the fans and compressor to shut off. If you find this either. Top of fridge in refrigerator section below temperature selection controls. Or remove toe plate, the pretty decor under the door. and it will be in there.
If this is an electronic style, look under that toe kick and there is a technician's sheet that will explain how to get into defrost.
Allow 10 minutes for heater to heat, listen for water sizzling on heater element. if this does work. you will need the defrost timer.
Hope this helps.

too defrost just open the doors for a day with the unit unplugged. as far as why it is frosting up check door seals make sure they are all good and seal it up well and that should take care of it.
