What's up guys?! This is my first post and hopefully someone will be able to help me out with my burned up portable AC unit.
The story: I just built an office in my shop and my dad did the electrical wiring. It's an old building and two traditional wall outlets ended up accidentally getting 220v instead of 115v. He was wiring up a ceiling fan when the temporary box fan we had in the room burned up. No melting or anything but there was a slight smell and the fan stopped running. It was old so we chaulked it up to just being an old fan that had finally died. About an hour later, I plugged up my portable AC unit to one of the effected outlets and I heard a pop. The unit has a reset button on the cord that I pressed and when I pressed the power button the LCD screen lit up for a second before it completely went out.
It was then that I realized the outlet was the problem child since two things had burned out on this outlet. I checked it with a volt meter and sure enough 220v. So, I began to tear down the portable AC unit in hopes of finding a blown fuse and an easy repair. I think plugging the unit in popped the fuse. I think pressing the reset button on the cord burned something on the circuit board that I'm unfamiliar with. Here are the pics of the circuit board and the obvious blown fuse, but what is this other thing to the left of it that looks fried? Do you think she will ever live again?
