Hi, i've been having problems with my Daikin inverter also. Its been shutting down randomly and I have to switch it off at the power board to get it back on again. Also, its not cooling the room very well at all, though it seems to work a bit better at night.

Anyway, I found the error code on my remote. It was F3 - Outdoor abnormal discharge temperature. Can anyone tell me what's involved with this and how to fix it?
