We had the same problem with the upper and freezer lights going bad. We purchased an extended warranty from Whirlpool. The serviceman could not repair the unit because the light module in the freezer (connected to upper lights) went bad and is covered with insulation. He called Whirlpool for help and they told him that it is not repairable and we need a new fridge. Our refrigerator is a top of the line Whirlpool with a MSRP of more than $3300. Whirlpool offered me an allowance of about $2,100 toward a replacement with no guarantee that the problem will not come back. That means a thousand bucks for their product that failed after about 13 months. Very frustrating. I think the consumer products Commissions and Consumer Reports need to look into the issue.
