Product review (1 stars): Defective initial design and poor Corporate assumption of responsibility!
Whirlpool did it again - making our world a little harder. The part apparently  fixes the problem but why did they not test the design to start with. I spent a whole morning disassembling the freezer compartment to get thawed out with a hair dryer. After discovering the real issue at the rear of the fridge I cut a V in the rubber plug to open up the slit to allow water to pass. That fixed it until the repair part was received.

What's next WP?
