Thanks again guys for all the help. Let me be clear though one more time... I don't actually have an ice build up problem. Nothing is freezing. I was in error about what a frozen air conditioner problem was all about as per my previous post.

That said... is it possible that a loose connection on the 120v wire inside the control box ofthe A/C could have caused some issues with the compressor starting and/or control board logic issues, even though the fans never seemed to have any issues? When I took the control box out tonight the 120v supply wires just fell out of the wire nuts. I think the wire nuts were stripped... they weren't holding anything. I decided it was worth putting it back together with good nuts and seeing. I spent over 2 hours cycling the air conditioner turning the thermostat up and down, and the thing never missed a beat. I would turn it up to shut the compressor off... let it run for 1 minute, then turn the thermostat down. It always took 2min 20seconds for the compressor to kick back on after turning the thermostat down.... which is how the manual describes it's operation. I also let it run for an hour straight at the lowest thermostat setting... no cycling, no ice buildup, and then cycled it a few times. It worked perfectly.

It seems that a loose wire would have caused something different than what I was experiencing... but maybe not? Maybe that was it? It seems now that either the loose wires were the issue, or there is an intermittent problem with the board that will come back to haunt me probably at the worst possible time...

I think at this point I'm going to chance it though and hope for the best since a new air conditioner isn't really in the budget right now... a new one is probably the way to go if this one needs repair, but the best case scenario is to use this one as long as possible...

thanks in advance...
