How to Troubleshoot & Replace Whirlpool AP6006464 / WP2200859 Cold Control

I used the model number to find the thermostat cold control switch on Appliance Parts Pro's web site and ordered the part. I had to remove a bracket that was on the new control unit because it was not correct. The switch was correct but the bracket and the sensor were different compared to the original control switch. The cover housing that held the switch was retained by one screw that I removed with a 1/4 nut driver. The cover was hinged at the other end allowing me to remove the old switch while the wiring and a control board stayed in place. I installed the switch after removing the bracket just as the original switch was. I attached the original knob that was removed from the old switch. I plugged the refrigerator in after the screw was put back in the cover and tightened lightly. The refrigerator came on immediately and is cooling like it should. 

I replaced the Thermostat and Defrost Timer. It was a fairly easy repair other than removing the old Defrost Timer. The way the manufacturer, in this case, Amana, mounts that unit with "clips" is just poor design and engineering. It is virtually impossible to get the timer out without damaging the mounts. I had to do some creative rework to mount the new timer. After 2 days, the fridge appears to be working properly with these new parts. The new parts were shipped Very Fast...APP is an excellent company! 

My freezer was working but the fridge was warm. I called a local repair guy., i gave him all the info on the fridge and the problem and he wanted $250 minimum without even coming to look at it. so i posted question on the site. got an answer back to the most likely part which was the cold control/ thermostat. . i read the other reviews on similiar repairs, i ordered the $85 part, installed it, All working again I had no idea what i was doing and it took all of 12 minutes. The hardest part was digging through my tool box to find a 1/4 inch nut driver 

Installed a new thermostat (cold control). 

Yes 

Ordered and installed new thermostat-this was the solution, now works fine 

Thermostats replaced 

Changed evaporator fan. Appliance Parts Pros.com had a You Tube like video that showed exactly what to do, step-by-step. Now my beer is a frosty 35 degrees. If that's not success I don't know what is.
