Do you have a model number located on a sticker near the ceiling of the refrigerator/freezer section?
So if the frost comes back it means that you have a freon leak or a defrost issue. Commonly on this model the evaporator behind the back panel will build up frost on one portion but not the other because it's low on freon and if that's the case your evaporator has a leak and would need to be replaced.
Now if you removed the back panel and the evaporator was packed with frost rom top to bottom, it means that the unit isn't defrosting on it's own.
As a last scenario, if the frost doesn't come back, it means that the door was just left cracked open which is why it built up frost/ice.
OK so you will need to leave it shut off with the doors open. It sounds like you must not have left the doors open if the frost is still there. If you don't leave the doors open the unit just acts like a cooler.
