I have a Kenmore model 59669932011 fridge with freezer compartment on bottom. Problem is bottom freezer compartment does not defrost and if left that way, it freezes up the bottom fins so much as to block coolest from reaching the top part making everything thaw out on top but freezes rock solid at the bottom part. Any help on where to start looking?

Hello,
You will need to get access to the defrost heater in the freezer section and check to see if it has burned up.. there is also a defrost bi-metal (thermostat) that would need to be checked too.. these to parts work together to turn on the heater to keep ice from building up.. if either fail you will have ice build up and it will not cool properly

ok keep me posted.. the ice should be removed all the way this will make it easy to get to the defrost heater ends.. a simple continuity test is all you need for the heater and if it is burnt you would likely see the burn marks anyways.. the defrost bi-metal should be tested for continuity while it is below 30 degrees .. it should show continuity below that temp.
Thanks

Checked defrost heating element, seems OK. Bi-metal defrost switch is not showing any conductivity even when I go down real cold with it. Looks like this may be the problem. Now to try and order one somewhere.
Again, thank you for all your help.

I was going to say, for a test on the bi-metal you can cut the wires to it if there isnt a connector and just wire it direct to see if the heater comes on once in defrost mode.. The bi-metal opens when it senses the heater has done enough therefore closing the electrical circuit and current to the heater.. this normally is done around 45 degrees.

Am I correct in thinking that if it doesn't close up that the defrost element will never come on or have power to it.
I am still looking for a replacement for it, very difficult with these even not so old Kenmore

correct, if the bi-metal is stuck open (no continuity)  there wont be power to the element during defrost cycle.
