We have two window A/C units, the 6,000 btu in our bedroom and the 12,000 btu here in the shop. Being in the high 80's this week, maybe 100 later today
I've been running this one most of the day to keep the laser air cool and allow me to work with the vinyl. The bedroom one we set to come on at 8pm and run all night.

Both of them are LG electronic/remote and both have the same problem.

After running a couple of hours the temperature setting changes itself to 72 (default). Last night I had the bedroom one set at 68 and had to change it back from 72 3-4 times during the night. The shop one I had to change twice in the afternoon.

I contacted LG by e-mail and their reply was "make sure you have the mode set to cooling." (Thanks a lot).

Any ideas, or should we just live with it? After all we normally only get a few weeks of this weather.
