I have an attic mounted Carrier Air Conditioner that is fairly new. Most of the year it works fine, but it consistently blows a 5A fuse when I first turn it on after it has been off for an extended period of time (e.g., turning it on for the first time in the spring, or turning it on after a week of cool weather).
I did not find any evidence of water accumulation in the unit, nor could I see any obvious failed capacitors.
Is it possible that the thermostat is wired incorrectly?
The blown fuse is shown below (I replaced it prior to taking this photo).5A
