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.
Used a flat head screwdriver to pop out the old switch, removed the contacts and placed on the new switch, popped the switch back in. Done in about 2 minutes.
Thawed out freezer, I recommend laying a couple old towels in freezer to soak up melted ice. Replaced old thermostat with new part. Removed 2 screws, removed back plate, unplugged 2 connectors and cut 2 wires. Crimped in new thermostat and repositioned to original part location. Reconnected plugs as I reinstalled back plate. Installed 2 screws and connected power. Works like new! Trouble shooting and part installation video is very helpful, great site!
The repair was not the issue. When I received it there was no protection packing, no invoice and if you call the number, no one is there to help. The rack was plastic with no protection in box and it was damaged. Tried to resolve this matter with no response. Will never go through part select again.
Ordered the Capacitor and the Thermostat Control. Parts were received in a matter of a few days, easy to install, but did not fix the problem. Had to call a repairman to fix the problem (compressor relay - this part not available to order for this model number with Parts Select). Will continue to use Parts Select in the future for other parts, but not happy that the actual part I needed was not available - had to use other methods.
Remove lower cardboard refrigerator panel. Carefully pull existing cracked fan blade off of the motor shaft and replace with new fan blade. Reinstall cardboard panel.
Figuring out how to remove the cracked door rack was the most complication I had. Once I figured out how to push it up it was easy to remove and then replace it with the new part by just placing it over the nobs and pushing down. No tools needed, just hands.
