How to Troubleshoot & Replace Whirlpool AP6009234 / WP4344725 Thermostat

Being that our under counter bar refrigerator was so expensive we called in a repair person to fix it. The refrigerator lit up when opened but didn't get cold. The repair man said he thought it was the thermostat but once he fixed that he couldn't be sure that was the only problem so once he fixed that for $300 there may be additional expenses. I went to this site and was able to easily find the part and ordered it. I then found a youtube video on how to replace the thermostat. It took a couple of hours but it worked. And now the refrigerator works. My total investment was 175. That's included the repair man's fee. I also bought a replacement ice guide for my kitchen refrigerator because the original ice guide got do gf over the years. This site has a video on how to replace it. It was simple.
