Product review (5 stars): great replacement part!
so far so good. this is what Whirlpool should be installing on the refrigerators, and hopefully they are now. Water begins to puddle outside the bottom freezer door. as most people reading this will have been dealing with. The old part clogs up which does not allow the defrost water to drain to the pan under the frige where it would evaporate.

 Replacing this part was relatively easy, but figuring out how to access the fins in the back of the freezer that were clogged with ice was not! in order to melt the ice and alleviate the issue, then put it all back together.

I would suggest letting the ice melt by itself by leaving the frige unplugged for a day or 2 if you have the time to do this, like if your leaving for the weekend and don't have a ton of food in it. Otherwise you will need to have to speed up the melt time
