Fedders a/c questions. The electronic control type.?

My wife tried to do me a favor 2 weeks ago, on my a/c unit. She took the front panel and the case off and hosed the unit thoroughly. The breaker on the cord Tripp's every time you try to plug it in. I myself removed the front panel, the case and the styrofoam blocks and cleaned using compressed air. I put the styrofoam blocks back together, plugged it in and it worked fine. Ran it for at a half hour, no unusual noises and put out cool air at 66 degrees. I then put the case back on,and the front panel. Once again I plugged it in and it worked fine, for another half hour. I called my neighbor over to help me install it in the window. I got everything secured, went to plug it in and I couldn't believe the breaker tripped again. It's on the same circuit as before, so that can't be the problem. I can't find anybody to work on the unit in this area.|||Fedders i think are not in business anymore. So people will not work on them also the parts were so outrageous you can go buy a new one for the same price. i will just go buy a new one|||Make sure the power is off. The most likely problem is you have water in the relays are usually located in a boxed off area very close to where the wire runs in. Blow that off and perhaps carefully use a blow dryer on it. If that doesn't work you better know how to use a multi-tester and go from there.
