LG Fridge Model LFD21860 Lights Remain On
« on: July 08, 2012, 06:44:45 PM »
The fridge "door open lights" don't always shut off. This causes the top portion of the fridge to get really warm - actually hot, hot enough to melt the plastic assembly that holds the incandescent light bulbs. Initially I suspected that one of the door switches was faulty causing an intermittent contact, but after removing both switches and checking the contacts & continuity, I found they were both OK. Based on this, I'm assuming that it must be a comparator in some chip that's failing and since there's only one place that I see where this could reside is the PCB - does this diagnosis seem correct or am I missing something simple?

One of the relays is probably stuck on the control board.
I looked up your model number and it uses control board part # 6871JB1423N
Hope you find our site helpful.

Thanks AJ & applicancedoc05, I appreciate your quick inputs. I finally got the fridge problem resolved, but not in a direct manner.  Here's what happened, hopefully it can help someone else in Canada:
 
   I called the number only to be told that my model didn't fall into any recall category
   Since the fridge was out of warranty, I decided to replace the PCB - it appears that in Canada, "functional" LG parts aren't available over the counter
   I called the LG Canada service number and was told that I couldn't buy this part since I wasn't a licensed tech - this finally got me pretty steamed up. I've designed, built, and repaired many things from automobiles to computers, but here, I wasn't allowed to change a circuit board
   I told the person on the help desk that I didn't appreciate their lack of fail-safe board design that almost caused a "fridge fire", and although they didn't acknowledge the problem in words, this did catch their attention and to make a long story short, they sent an LG tech to fix my problem at their cost. It appears that they will fix this issue on a case-by-case basis & if contacted personally. There's a repair kit to handle this, it consists of a new (and improved) PCB and a new interior fridge light assembly & this light assembly also contains a thermostat that will shut off the lights should that area get hot
