Shop AC Broken Already???

We spent two days up north and came home to mid 80s with ALL THE HUMIDITY. After power washing all the mud and bugs off of the truck, I put it away in the shop. Having the big door open for a minute or so plus the heat of the truck itself was enough to make it slightly uncomfortable in there.

Soooo…a good excuse to use the AC for the first time! Turned it on, fan starting running everything looked good. But the heat gun told another story. After a couple minutes running the ducting had not cooled down one bit. I climbed up on the inception shed right next to the ducting and verified there was no cold air coming out.

I headed out back and noted the outdoor unit was not running. I verified I had 240v at the AC disconnect so I started to suspect the refrigerant had leaked out since the unit had power and it seemed unlikely any components would have broken from sitting a few weeks since working last. I have an AC gauge set for automotive AC but nothing for home systems so I decided to check the only other thing I could think of before making a call:

Simple as that. The trigger wire on the thermostat for the outdoor unit was apparently not secured properly and had popped out. I was pleased it wasn’t an issue with my wiring and it was such a minor fix I won’t bother to say anything about it.
