bottom not cold and freezer back iced up
I automatically assumed it was the defrost timer contcts or motor due to 2 previous experiences. After seeing troubleshooting guide in check out page of partselect.com site I tested the 2 other components and found defective defrost thermostat. Thanks to this guide I saved a lot of time and cost.

Freezer was not defrosting
In the freezer section I disassembled the paneling and remeoved the old bi-metal by cutting the wires (make sure your cut has enough slack to do splicing). Then, stripped 1/4 inch of wire insulation from the wire and used a wire splice to connect the new bi-metal and after that I crimp the wire slice. After all of that, I reassembled the paneling plug in the refrigerator and presto!! (Unplugging the regfrigerator should be the first step). The paneling is easy to remove, all the tools that are required is 1/4" nut driver.

Freezer Frosting
My problem was that the freezer was frosting up.
I have a no frost system so I decided to investigate.
I removed the panels inside the freezer compartment.
This took me about 5 minutes. After the ice had melted, I noticed that the clicks-on (bi-metal stat)
has the top push out at about a 45% angle.
After ordering a replacement, I pushed the top of the bi-metal down to where it's supposed to be.
Put the freezer back together and plugged it in. I needed the freezer while the part is being shipped.
The part arrived in about 3 days, which was very fast and a surprise to me.
The freezer was still working fine so I put the part in the drawer until I needed it.
That was in April 09 and it is still working. I have the part in case I need it.
I am very happy with the service I received from PartSelect and will recommend them to everyone.

Freezer icing up
Freezer was running for extremely long periods I noticed and not doing a great job of cooling the fridge.I assumed it was in need of a defrosting so I took the panel off to take a look.
The whole radiator was covered with ice.I could see the defrost thermostat was half way popped out of its casing at a 45 degree angle.
I just had to cut the 2 wires to the defrost thermostat and wire nut the new one in.Very easy fix as the part just clips on radiator.

Freezer was cooling but refridgerator was not
The evaporator coil was fully coated with ice. When all the ice melted the 2 leads on the old defrost thermostat (which was defective -- the gel was protruding over the top of the thermostat) were cut and the old thermostat removed. The leads from the new thermostat (bought from PartSelect) were re-attached to the wires that were previously cut and the defrost thermostat snapped back onto the evaporator coil.
