Product review (4 stars): New P-trap corrected the problem and was a very easy install!
This part was for my Kenmore fridge and it corrected the problem. My warranty was recently up on my fridge (always happens that way doesn't it?). I probably could have got the part for free from whirlpool but I bought the part anyway. The problem was that there was a huge layer of ice that would form on the bottom of the freezer within just a few days. The heater (that's right freezers have heaters) did its job and melted the excess ice but the problem was that the defective valve (rubber grommet) was plugged up and did not drain correctly. Very poor design. There are literally thousands of people that have this fridge or some whirlpool equivalent fridge that had this problem. Don't waste your time buying the equivalent re-designed grommet. Look on youtube to find out how to install this. It was a very easy install. I did not remove any food from the fridge. Once you unplug just keep the doors shut. I  was able to install in about 30 minutes.
