Product review (5 stars): Awesome kit fixes known defect in Whirlpool french door refrigerators
Fixed my Whirlpool french door fridge that had ice building up in the bottom of the freezer compartment because the terrible drain system that came with the fridge was clogged and not allowing water to drain into the drain pan in the back.  Found a great Youtube video on how to make the repair, you have to empty out the freezer compartment and remove the plastic at the back so you can defrost the coil and the drain with a hairdryer, if you don't then this drain still won't work as the ice will prevent water from getting to it in the first place.  Whirlpool has long known this was a defect and initially extended the warranty on some of these fridges and now will only give you this kit if you call up and yell at them long enough, you are still responsible for paying a tech to do it.  I figured that it  was easier to pay eleven bucks and do it myself, the job took about an hour including emptying the freezer out.  If you don't want to use the hairdryer, Whirlpool has an awesome video that tells you to unplug the fridge for 24-48 hours so it can defrost, obviously where to put everything that was in the fridge for two days is not their problem.  Anyhow, this kit works wonders and is definitely not something you need to pay a tech to do!
