Product review (5 stars): Good price, easy to install
When we returned from vacation, we discovered our Kenmore (Whirlpool) refrigerator had stopped working.  After a little troubleshooting, I deduced this thermostat was at fault.  Being a Kenmore, I looked at the Sears website for a part. It was $80, which seemed high, so I searched the part number on Amazon, finding the exact same part (same number, same manufacturer) for $20.

It took less than 30 minutes to install, and it has been working now for more than six months.  Thanks, Amazon!
