It's wrecked. The fridge part will not get cold. The only way to fix it would be to put a new evaperator in it, but that would cost way more than that thing is worth. Next time use a hair dryer. Sorry that happened.

If you can seal the hole, than more power to ya. They do make a repair kit for those, it consists of a crayon looking thing. You will have no refrigerant "gas" left, it has all leaked out. If you want to try the kit you can. But you will need to be epa certified to buy the refrigerant, you need a vacuum pump, gauges or a refrigerant scale, line taps, and a new filter dryer, not to mention the compressor may be contaminated now and may need replacing also. Basically for the average homeowner, this is not possible for you to do. But trust me on this one, there is no refrigerant "gas"left in the system which means it will not cool even alittle bit.
