In the theme of critters declaring war on the Old Vic (see previous raccoon wars posts here and here), I now know the Gree Mini-split AC error code for (insert best Samuel L. Jackson voice here), “I’m tired of these #&@^&* snakes in this #&@^&* air-conditioner.”
Yes, for some reason a snake assaulted one of our AC units. He lost. Hopefully he didn’t get a chance to summon reinforcements.
Unit detected the error condition (fan malfunction) and shut down with an error-code. At least the fix was simple!
