Why does my window A/C unit keep turning off?

-We have this huge window A/C unit. It is literally about 1 1/2 month old. We got it out of the package, brand new from Lowe's. It's a 25,000 BTU so it doesn't run on the "normal" outlets in the house. The outlet the A/C does run on has its very own circuit in the house. Today I noticed that it keeps shutting off, and I have to press the "Reset" button on the A/C plug (part of the A/C not the wall outlet). What could be causing this to happen and how do I fix it?It's probably a problem with the A/C itself. It would be hard to tell what the problem is without actually looking at it. Try calling the place where you bought it from, they might actually still be able to give you an exchange. They did that for me (even when it was over the 30 day mark) before with a similar situation.If it's still under warranty, take it back to the store and exchange it for a new one. Even the best brands have an occasional lemon; that's why they come with warranties.
Is it on "energy saver" mode? If so, it will shut off when the room reaches a certain temperature.
