I will answer the questions I can until I get home tonight and check it out.
The battery is not a factor. I do not have a battery on my system. It's either plugged in or nothing. The breaker was a little warm. I had to replace the main breaker last year. Do these go bad normally? I have not checked the connections yet. The unit was cooling great- you could hang a side of beef in there. I had it running all last week when my daughter was " camping out" and had no problems. I can't remember when the condenser was cleaned last, but I will check it tonight.
