My Whirlpool Duet dryer gets very hot and blows the thermo fuse. The fault code was F3E2. I have replaced the thermo fuse, the exhaust thermistor and cleaned the vent. The thermo cut off and the high limit thermostat has conductivity. After I replaced the fuse and the exhaust thermistor, it dried one load then the thermo fuse blew again. I also checked the heating coil and it is not touching the housing and nothing is warped. What is causing my dryer to over heat and not work. 
What is the complete model number of the dryer?
