Mike, Thank you for your quick reply since we are melting...:) Actually we did check the fan and all the inside workings of the air conditioner and the water (condensation)from all the humid weather we have, was overflowing the pan, hence hitting the wire and tripping the breaker. We thought after cleaning out all of the gook that had accumulated, all was fixed. It worked fine all evening,but tripped again this morning. We are going to replace the breaker today since it seemed loose, alot looser than all the others, plus the fact we are trying to dry out all the insides of the unit with just running the fan for the time being. So, it seems you were right on the money with your answer, all you had said was correct. We have been having brown outs here in Fort Worth & Dallas, it seems it is the electricity's company way of avoiding a total blackout. They had been shutting down the electricity in different parts of the city for about 15 minutes at a time, without warning I might add! It has caused major problems with refrigerator condensors and such, I will not even go into the computer problems it has caused for many businesses and home users. But of course, they have a deaf ear to the little man's problems and continue on their course of action, justifying it with it being for the greater good of all concerned. Yeah right! I will let you know if changing the breaker completes the process of the air staying on all the time and not tripping anymore. Thank you both who had answered, it did help alot and just knowing this forum is here for answers is a great relief....this house is old, so, I will probably be here for awhile...LOL. Dakota
