I've got an LG Ductless 12000 BTU unit that does the most annoying thing..
It is wired into a semi-standard (one of the prongs is sideways) 15A or 20A (can't recall) GFCI outlet inside - and if the power goes out, or I bump the cord "the wrong way" and it manages to lose power.
Then I can't get it to turn back on.
It has always been a bit finicky. When it was first installed and this happened, it would sometimes take 3 minutes (as it should), sometimes an hour. It was never consistent.
Now it takes hours, or sometimes even days. Last time my power went out it stayed off for three days. I've tried everything. Cleaning it, coaxing it, check all the connections. But nothing works. Then, just randomly, it comes back on. I asked all my neighbors if they had done anything with their electricity immediately when it happened, and no, they hadn't.
Since I installed it, the electrical in the building has been upgraded. So if anything, it should be more reliable now.
Any ideas how I can ensure that it restarts immediately?
Could it be a ground issue? If so, or otherwise, how can I troubleshoot it?
