Sorry, but you are only half right. The sensor was designed to keep the cooling coils from overheating, that's right. If the cooling coils overheat and the red light comes on with the sensor your refrigerator shuts down, it does not cool, and if you bypass it then you are risking the liability occuring that it was design to avoid for Norcold. In other words, if your refrigerator overheats and catches fire you are on your own. If the sensor trips your food will spoil unless you can get to a repair shop and have another sensor installed. That is a fact! Now, my coils blew after they installed the sensor. The red light came on like it was suppose to come on. Did the coils blow before the red light came on or after it came on? Who knows? I fixed it, I put in new coils, my food doesn't spoil.
