    Yeah, the condensation is OK.

    The thermal trip will reset itself as soon as it cools off.

    Thanks for chiming in Ron.

    Ok, so you're saying that the radiator fans likely turned off from the breaker tripping as Dave mentioned, but then came back on when the breaker cooled?

    So does this mean something IS wrong with my A/C (non)cycling then?

    Yes the breakers reset them self. There was a recall that replaced the original 30 amp breaker with a 40 amp breaker. OEM fans draw more power as they age. I always recommend updating your cooling fans to one of the vendors low power fans.

    Yes (check for 40A upgrade Dave mentions).

    No...separate circuits. The AC/mode switch OR the Otterstat can send power to the fan relay to turn them on (through the breaker ). The AC/mode switch feeds the cycle switch separately. ie the breaker is not in the circuit.

    Usually one will cycle some...but, if the ambient temp, pressures, etc are just right, it can be like watching for a pot of water to boil ;-) The evaporator may "freeze up" otherwise...
    I agree with getting the fans to stay on while the AC is on

    Thanks for the quick replies guys, much appreciated! Hopefully nothing's wrong with the AC system itself, like a blockage, faulty pressure switch, etc. Everything was ok just this past April.

    About the fans and the current.... it's funny, I have actually had a brand new set of Houston fans sitting on my workbench for the past couple of months. Been waiting for our stinking hot miserable summer to end so I could install them without dying of a heat stroke. Looks like the time may finally be upon us! I'll check out the breaker too, to see if it's the 40 amp one.

    Now that you describe the ways the fans get power, yep, totally sounds familiar -- I remember studying the diagram when trying to figure out why my one cooling fan didn't work a few months ago. But if I don't repeatedly use the knowledge, it goes away these days.
