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.

ice machine was now working correctly
watched the video (VERY helpful) and then removed the old icemaker and replaced it with the new one. Difficult only because of the small working space in the side by side freezer plus you can't see what you're doing when you tighten the screws. Working like a charm now.

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.

Refrigerator was not cooling and the motor was running constantly
Having tried PartSelect.com before, I was very comfortable with the process. Input my symptoms and the feed back I received was that one of the 2 things (Defrost Timer or Defrost Thermostat)might need replacement. Since the cost was not much and over night shipping would cost more than the product, I decided to order both the parts. Changing parts was a breeze. The instructions posted by others on your web site were very easy to follow. You guys save me a bundle every time I have any thing going worng with any of my appliances.

I ept finding clumps of ice in try as though water was spilling over ice maker tray.
I loosened the 2 1/4 inch nuts with a nut driver, disconnected the wire harness, and removed the old unit. to replace, I simply connected the harness and bolted the unit back in. The job took about 10 to 15 minutes and the new unit works better than the old one ever did.

Ice Maker stopped working
Removed 2 screws that hold ice maker in place. Unplugged and took out of freezer. Used the screws I took out to put new ice maker in. Plugged in the power and in 2 days I had a full ice bin and haven't had any worries since. Should have replaced the broken one along time ago but thought that the process was harder than this. Very easy and suggest this to anyone having ice maker issues. Less than $100 and never have to buy ice for the house again.

Temperature in both freezer and fridge sections to warm!
Dear Part-select,
I had a fridge that was not working food was melting in the freezer, Beer was warm. You get the picture anyway using your site I found the parts needed to to fix the issue in fact I ordered two parts one fixed the issue 50% and the other like 30% of the time! both parts with overnight shipping were cheaper than 1 part if purchased at our local appliance part outlet:) not to mention the cost of a repair person. Thanks again! . Keep up the good work

Ice Maker not producing / Clicking / Off-cycle
We love our ice here. I seem to replace the ice makers one to two times a year. Generally the ice cycle gets off for some reason and it starts making loud popping/clicking noises (gear grinding). Its easy to replace. Simply loosen two screws holding the unit to inside of freezer and disconnecting the wiring harness. Unit slide up and out. Replacement is super easy (5 mins or less). Bam! Ice!

Ice maker stopped producing Ice.
After determining the ice maker was getting water but not harvesting the ice, I ordered a replacement Ice Maker. Installation was easy. One electrical connection and two screws. Following the video to make sure I did not miss any steps I had ice in just a few hours. Just in time for a July heat wave!
