Before you decide on buying or ordering, do your due diligence and double check the correct model as well as make a visual inspection in order to be sure the right thermistor is the one being purchased. If you are unsure about the correct way of installing the thermistor by yourself then it is probably best to contact a professional to do the replacement of the part.
