Most refrigerators have a switch somewhere. look for a little white triangle either at the top or bottom. there may be a push button style somewhere along the upper hinge cover.

Warranty time, call maytag, most fridge come with 1 year warranty.

you checked your cooling system.

controller of cooling may be get damaged.

I have bad news for you. EAch of your shelves is part of the evaporator coil. This is the coil where the liquid refrigerant expands into a vapor. If only one shelf has frost, and the other shelves no longer do, then you have a low side sealed system leak of your refrigerant. You could have it repaired, but that is a major service call, and to have it repaired properly to EPA regulations, it is quite expensive.
sorry
