Product review (5 stars): Saved $1190
I admit my refrigerator is nearly 15 years old and when it stopped working, I went to buy another (over $1200).  Described my problem to someone on a online site and based upon my description, they said ALL YOU NEED IS THIS PART!  I took a chance for around $10, my refrigerator is now working great again!  More specific, my refrigerator was freezing up, i.e. the coil was clogged with ice and wasn't sending cold air to the freezer or cold storage part of my refrigerator.  This thermostat clips to a coil and sends a signal that heats the coil long enough to defrost the build-up of frost and ice, allowing the fan to blow air through the coil and into the freezer and cold storage areas to keep everything at proper temperature.  For $10, I gambled and it worked!  Thanks to online support and quick shipping, I am back to normal.  SPECIAL NOTE:  Part numbers change over time so the number on original part in my refrigerator had to be cross-referenced to the present part number.  When looking online, different websites had both and/or either part number.  I did my research and this was the BEST price by far.  PRIME MEMBER so shipping was free.  Sites that had the part cheaper, were more expensive once you added shipping costs into the total price.
