I've got a service appointment on the 31st. If you don't find out what it is before then, I'll let you know.

It could be that cycling the fan from max to auto cycles the compressor, but really don't have any idea at this point. Too many computers. Does yours have the automagic climate control (set to temperature)? That's what I'm working with.
