Thanks for the info. Ill check out the sensor. As far as the resistor, if it is broken it should stop current flow because I did get the fan to come on for a short period by bypassing the resistor which is what led me to believe that is the problem. I will order new resistors then try that and see if that helps. If not then its on to the sensors.
