Had to drag the full freezer out from the wall to expose the name plate, got the Model # and S/N and found the key on the partselect website in minutes. It was cheap so I got two. Other than FEDEX not knowing my address correctly, when I finally got the key it worked fine. Not a problem anymore.
Thanks

HAD TO REMOVE ALL SCREWS ON REAR BACK COVER OF FREEZER INSIDE, UNPLUGGED REFRIDGERATOR, UNCLIPED THERMOSTAT, UNPLUGED THERMOSTAT. REPLACED THERMOSTAT WITH NEW ONE IN THE SAME LOCATION, AND LET DEFROST FULLEY. REASSEMBLED, PLUGED IN, AND TESTED. ALL WAS GOOD. BUT I DID ALSO REPLACE TIMER AT FIRST PART OF THE REPAIR SO I SUGGEST YOU REPLACE BOTH AT THE SAME TIME.

Removed the back panel in freezer compartment with the nut-driver. Then I cut off old thermostat connections, and spliced in new thermostat connections (repairman had already replaced defrost timer, and said not to trust connectors included on wires-they failed often). Then I snapped thermostat itself onto cooler coil. So far so good, fridge is running at 35-40 degrees a week later. Thanks Parts-Select!!!

Cooling coils would ice up and fridge would warm up

I removed the shelves in the freezer, took out the five 1/4" screws and lifted off the cover. It was a simple matter of using a blow drier to remove all the ice, then unplugging the two wires and unclipping the thermostat from the upper cooling tube. Then clipped the new one on and reconnecting the two wires.

Works great!!!

I first replaced the defrost timer about a week prior and it did not correct the problem. I then ordered the thermostat from partselect and within 15 minutes had the part installed. My refridgerator has been running correctly for a couple weeks.

defrost thermostat was open most of the time and didn't let the defrost element heat up.

I ORDER ANOTHER ONE THANKS

Controller showed signs of the plastic housing had melted.

I paid attention to how the old part came off. You need a small (very small) flat bladed screwdriver to release the two wires that plug into the controller. I checked that it was a bit difficult but it would had been easier if I could have found a screwdriver sooner.

Fridge was getting warm while the freezer was cold and running constantly.

After testing and eliminating the temperature control and the timer as the problem, I turned to the thermostat. I had to wait for the ice buildup to thaw and then could remove the rear freezer panel (this was the 3rd time: first, to discover the ice buildup causing the problem, second when it came back after a complete thaw and test the thermostat, and this time to put the Partselect thermostat back in). My thermostat was visibly damaged from water melting into ice and expanding the casing and eventually breaking one of the connections. I connected the thermostat connection wires (not recommended) to get by while ordering the part, which shipped faster than local repair places could get it from their warehouses, and at a fraction of the cost. I'm really impressed with partselect's fast service and all the knowledgable customers who have explained how they installed them. I now have an intimate knowledge of how my fridge works and saved hundreds in repair, or twice that in replacement. Thanks!

Freezer part worked well, but refrigerator part did not cool down bellow 60F. These is a top freezer model. When I looked there was lots of frost on back panel of freezer.

First of all thanks to all who posted their stories, because those stories helped me to narrow down what could have gone wrong with my fridge. I did not know how frost-free refrigerators worked at all, reading your stories and doing some on_line research I understood the theory behind the work. My freezer was working constantly, but fridge was warm, cold air would not reach to fridge because freezer was completely frosted.
I had ordered defrost heater, defrost timer and thermostat. I was sure one of these parts was the problem.
First I used flat screwdriver to turn the timer manually untill frdge stopped running(timer is on the left bottom corner behind the black decoratve plastic under the door) . Waited about 20-30 min, checked ,freezer was still frosted. I disconnected the fridge from the wall socket and took shelves out from freezer compartment. This is where hair-dryer came in handy or you could wait till ice would melt on its own, which could take long time.Then loosend 2 screws on left wall that were holding icemaker unit half-way , unplugged the icemaker and took it out. Then took the light-bulb and cover off. Next I unscrewed and took the posts out that were holding shelves in place. Then I took remaining screws from back wall out and gently pulled back cover up then forward a little until I could see electrical connectors behind the cover and unpluged them. Back wall cover was ready to come out. I discovered thick wall of ice covering entire cooling unit. Used handy hair dryer again. When the ice melted, I saw the thermostat was busted open ( Iguess water or moisture got into the unit, then froze and ice pop-openned the cover damaging one of the connecting wires). I diconnected wires and changed the thermostat , which was very easy, just one clip holding it in place . Then plugged the fridge and checked if heating unit was working by touching it. Negative. Closed the door and let fridge run for 15 min, turn timer with screwdriver until fridge stopped working, cheked heater again- wallah it was warm and then it got really HOT! and melted all of the new frost build-up(a sign that thermostat was working). Closed the door waited another 15-20 min, fridge came-on on its own. Unplugged the fridge, pulled it forward from the wall and used sponge to drain the water from holding tray- about one half gallon of it. This is a good time to use a vacuum clener to undust the back and under the fridge. Then put everything back, in reverse order, ofcourse. Cleaned fridge and freezer compartments with warm soap and winneger solution (really good- this was a present to my wife who took our two little daughters to grandmmas and out of my way), put everything back and turned the fridge on recommended settings. Its been 5 days allready and it works great ( I used thermometr to check temperature inside the fridge and freezer). I'm thinking of returning defrost heater and timer back.Thanks PartSelect.Com, I saved lots of money. Hope this story will be helpfull to someone.Thanks for your time!

Took about an hour previously to deice freezer, timer was running,drain was open, jumped defrost thermostat out and heater was O.K. Defrost thermostat was just a plug and play item, the time involved was in taking the freezer apart to get to it.

Freezer was building up ice. Running constantly.

Parts Select is an excellent source for help and parts identification. I highly recomend them.
My first option was to replace the defrost timer.
After still getting ice and frost buildup in freezer I decided to replace the defrost thermostat.
Remove all shelves. Losen icemaker if applicable. Remove light cover and bulb. Remove all screws securing rear vertical cover. Carefully move back panel, disconnect icemaker and bulb assembly. carefully remove styrofoam cover at upper left and remove defrost thermostat. I tested the thermostat and found it was defective. It would not close circuit after being placed in a working freezer. Reverse procedure to replace thermostat.
This solved the problem
