Frost free Refrigerators go into defrost cycle every 6-12 hours depending on model.
If frost become visible, on of the defrost system (Defrost timer,Defrost heater, Defrost thermostat) components has failed. The most common failure is the defrost time. If you can locate the time, try to advance it (rotating) into defrost and if you see water coming into the drain-pan within a couple of minutes, than the Heater and thermostat are OK and you need to replace the timer (relatively easy job). If no defrost occur , you better call a tech and avoid replacing unnecessary parts. Caution - Some defrost timer are incorporated into the Ice Maker mechanism are hard to test and must replace the entrie Ice Maker

You have a sealed system problem. There is either a small leak or a restriction somewhere in the tubing. This isn't something you could've caused so don't worry about that. Unfortunately this isn't something you can fix yourself either. You require a certified refrigeration technician to fix this problem.

I went to the Amana web page and looked up model #. They have the parts lists w/ prices and exploded parts drawings available. This will enable me to repair our unit.

Almost certainly, you have a leak within the freezer compartment.
The cooling system will use a divertor valve to concentrate coolant to the fridge or freezer compartment - whichever is necessary to maintain selected temperatures.
If a seal within either compartment is compromised and leaks then the coolant will be excessively diverted to that area in an attempt to lower it's temperature - the other section will suffer since more coolant is diverted to the weaker area; the weaker area that is being excessively cooled will also have more moist air circulating, hence moisture will contribute to a build up of ice - exacerbating the problem.
Ensure that both fridge and freezer doors are closing properly, if they appear to be secure then also check that the seals are airtight - there should be no ice accumulating around them.
You might need to re-align the doors, or less likely, replace the door seals.
Please reply if you require further clarification or help.

The frost should be uniform on the coils. Uneven frost pattern is a sign of low freon. Most systems are sealed but a qualified tech can recharge the system after finding the leak and cap it off.

I have this problem as well, only nobody is leaving anything open. The defroster is defective of these things and the duct between the fridge and freezer gets frozen over and the cold air can't get in the fridge, so the freezer keeps working until it's blue in the face.
