Product review (4 stars): IF YOUR CHILL DRAWER AND FREEZER LIGHT AREN'T WORKING READ THIS!!!!
Just received my new LG refrigerator with custom chill drawer and the drawer wasn't getting power and the freezer light wasn't working.  Read many bad reviews with these same issues and decided to take matters into my own hands.  I opened all of the wiring compartments on top and re-seated them with no results.  Then looked on page 19 of manual which is the assembling of the custom chill drawer and discovered that there is a wiring harness in the chill drawer itself.  I took out the inner drawer and discovered that when the installers had put the inside drawer back in it had dislodged the wiring harness inside.  I re-seated the harness and now all is working perfectly just be careful when putting the inside part back.  I imagine that when people say that it worked fine and stopped working after a short while that this is the same issue.  Hope this helps anyone having this issue and saves you money and aggravation!
