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!!!

My Freezer Was Frosting Up, My Ice Maker Was Not Working ,And My Fridge Was Warm.
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.

the refrig was in storage for about a year, the freezer door warped
removed freezer door and installed the new one. This was a pretty easy thing to do, although putting the old handle on the new door was a challenge. No knowing that there is a plastic piece holding the top of the handle i broke the that piece and had to order another one. Mean while the freezer was making alot of frost inside, so that had to be cleaned after the new part came.

Freezer fine, fridge too hot!
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!!!

The original support was broken, tried epoxy and it only held for a few months before breaking again
All I had to do was remove the original support that was on the inside wall of the refrigerator, which I had to use pliers since there were broken pieces, and then I just snapped the new one into the three holes provided for this support. The crisper drawer works fine now. It literally only took about 1 minute.

first fresh food too hot, then freezer too hot
Based on the website I decided it was most probably the defrost timer, and that was correct. I ordered it, watched the video, and two days later the part was at my door. Took the nut driver, removed 4 screws, then removed the old defrost timer, installed the new one, re-installed the whole plastic assembly with the four screws, and done!!! Couldn't have been easier.

Frost in freezer, fridge not cold
From most posts I've read, the defrost timer was the culprit so I blindly ordered one. Easy install but did not fix the problem so I broke out the ohm meter. The only other 2 items it could be all tested good with my meter so I bypassed the defrost thermostat (per forum help...actually quite easy)and it defrosted fine, which told me I needed a new defrost thermostat. Installed fairly easy and problem gone.

Fridge quit working.
A little research told me the hum plus no cooling was either the compressor or the relay. I ordered the new relay and put it in but it didn't fix the problem. I ended up having to buy a new fridge, but it was worth the $30 gamble to see if I could fix it on the cheap and it saved me the money a service call would've cost. Pretty easy installation, just in a tight space on my model.
