I did this modification myself also based on the help here - thank you! It's a good idea to get it done or do it yourself because the problem has to do with that very small thermostat power wire being powered directly from the 15 Amp DC power line to the air conditioner control module. I can only assume that the dedicated thermostat power line coming from the AC controller is more current limited and tiny wire gauge friendly. I'm surprised their installation people didn't catch something like this at the design stage. It's not a major issue but like someone said, it could be a problem if the thermostat or it's wiring were compromised.

If you can wire a light socket you can do this fix yourself in about 15 minutes or less. Just remember to pull the DC fuse to the air conditioner so you don't risk blowing it while the DC power wire is exposed.
