my 3 year old haier a/c unit stopped working and instead of tossing it i

plug in the power cord i hear an audible beep, the power board (fan

of the controls work. it was moved last winter whilst in storage and
accidentally dropped. thoughts, comments?
thanks, cj

You might have cracked/bent and broken the circuit board. I would
think it only has copper traces (wire substitutes) on one or two
sides, not in the middle. See which traces are broken, even a small
crack with no visible light coming through is probably a break) and
solder jumper wires from one solder point to another (rather than
trying to solder to the trace. Although you can do that too, I think,
if you scrape the varnish off the copper, which sometimes is thin.)

Also see which parts are broken, a wire leed pulled out of a small
capacitor. That could be a bigger problem but you probably won't find
anything like that.

My roommate long ago had a an AM/FM/TV alarm clock. I've never seen
another one. His father got mad and threw it at him, he told me. The
circuit board was bent and cracked and sepearated, and I had to run 13
jumper wires, but after that it worked fine.
