WRF990SLAM00 this is the "do not EVER buy another Whirlpool Corp appliance for as long as you live" example. Whirlpool, Maytag, KitchenAid, JennAir, Amana, Gladiator GarageWorks, Inglis, Estate, Brastemp, Bauknecht, Ignis, Indesit, and Consul

19.5 months from purchase - compressor fails. Whirlpool "that's unfortunate"
3 months later - main power supply board fails. Whirlpool "too bad for you"
4 months later - crisper/deli/meat drawer control fails. Whirlpool "that's why we warranty things for 18 months."

So we gave up and bought a Samsung and could not be happier.

The Whirlpool, know known as the Failurator, is relegated to the garage where it has managed to keep cold things cold and (not yet anyway) caught on fire and burned the house down.

But since the first repair one thing as been consistent: The Freezer, even when set to it's lowest temperature (1 degree) can not completely freeze water. At best water gets "icy" and crunchy but never solid.

On the old top freezer units that are still running 10,20 30 and 40 years later, there is a simple vent system that circulates cold air between freezer and refrigerator (meaning that the temperature differential is a mechanical process) but I see no such air channeling on the Failurator.

How do I debug the freezer not being cold enough?
