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?

It sounds like you've got a faulty unit. Is it still under warranty? If so take it back and get a replacement. –  ChrisF Sep 10 '11 at 21:48
    
not under warranty any longer.. but it does come back on, just after an indiscriminate amount of time... must be troubleshoot able, no? –  alex gray Sep 10 '11 at 22:32
    
Have you checked the outlet itself? A GFCI receptacle tester will let you know if it's wired properly and if the GFCI is working and let you eliminate one variable. –  Niall C. Sep 11 '11 at 0:39
    
well, i studied up on gfci, and it tests AOK. i believe it is a lutron, and TESTing it turns OFF the green light, resetting it RE-enables the light. AKA the green light is ON. this supposedly indicates everything is AOK. –  alex gray Sep 11 '11 at 1:08
    
Does it not come on at all, or does it come on but just not get cold (e.g. the compressor never kicks over)? –  Tim Post Oct 13 '11 at 13:22
