If you are going to be buying or ordering do your best and make sure of the correct model as well as make a visual comparison in order to be sure the correct thermistor is the one being purchased. If you are unsure about the installation of the new thermistor on your own then it is probably best to find a professional in your area to do the replacement of the part.
