Question about Maytag 21.0 Cu. Ft. Top-Mount Refrigerator - Black
Assuming that your refrigerator is a frost free, the problem is the defrost circuit has failed. It consists of the defrost timer, heater and thermostat. The timer turns power off from the compressor and turns on the heater which melts frost on the evaporator coil. If any of the three parts fail then ice will build up.

SOURCE: Ice building up in freezer
Due to the frosting up, The glass defrost heater broke. Any good tech knows this happens. The defrost heater must be replaced. If this is a GE side by side. The new replacement heater has dual elements. The standard heater that was put in them, was not large enough to defrost the coils fully. Replace heater and you should be fixed up. I would also replace the thermostat while you are in the freezer section they are only like 15 bucks and this way you will have a new defrost circuit.

Your evaporator coils frost up in normal use
and every eight hours or so the entire unit shuts down and the defrost heater
comes on to melt the frost. This cycle last about 20 minutes. The melted frost
drips into a drain pan and through a drain tube to the drain tray under the
freezer/refrigerator where it's evaporated by the condenser fan.
Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer.

There's a drain hole in the freezer side behind the bottom drawer in the back wall that must be clogh ; put hot water into it untill melted the ice and keep pouring water to clean the drain (don't worry , the water goes to an evaporative tray) .Keep the drain clean by putting every 3/4 months half a cup of clorox or bleach.
