We had huge problems with the double-door LG Intellocool (or whatever the model is called).
First, within 2 months of purchase cooling was lost and the outer surface of the unit in fact started to warm up; hot to touch. It was supposed to be a leakage of the coolant gas, as per the LG technician. We demanded a replacement, since it was hardly 2months old, but the seller was only willing to go as far as refilling. After much effort he ultimately replaced the refrigerator.
Just a month after warranty expired, some component failed in this replaced (i.e. new) unit...same symptoms...no cooling and hot exterior. We had no extended warranty and set back by around Rs.2000 for part replacement.
So, personally, I don't suggest LG, though I know they sell like hotcakes and maybe it was just my luck.
