Removed lower panel... Two nuts bottom left and right. Take the time to vacuum out lint deposits. Directly behind blower housing on top of exhaust are two sensors. Right one with two parallel contacts is Thermistor. Need to reach around housing a bit... Two nuts same size as panel nuts but much shorter and part comes off easily. Align new Thermistor and seat it in opening, attach with nuts, attach wires, replace lower panel. Total time... 8 minutes.
