Condensing unit was icing over.
I've seen the inside cooling coils ice up - is that what you're saying Steve? From what I understand this occcurs because of imporper refrigerant charge and/or insufficient air flow (which then gets worse as ice builds up).
I don't believe I've ever heard of an ice-up on the outside condensor unit, but then I'm no expert in this. I have a friend who is an AC service guy, and I'll ask him about it when I see him again.
