My Kenmore Elite electric dryer (MOD: 110.62084101) keeps blowing the thermal fuse. I have cleaned the ducts (the airflow is great) and replaced both the fuse and the thermostat, but the fuse seems to last only about 30 days. The heater coil is NOT grounded and the thermostat is NOT faulty. I tested the thermostat by checking the continuity with the multimeter while holding an open flame from a lighter on the thermostat; it opens the circuit when it’s heated and closes the circuit when it cools off, like it’s supposed to. I have already replaced two sets of fuses and thermostats and both times the thermostat was working, so I’m pretty sure that the temperature near the fuse is not equal to the temperature near the thermostat; I don’t know why. I’m running out of ideas. I’m considering hammering the heater housing duct where the thermostat is attached, so the the thermostat is deeper into the heater housing duct, which will hopefully allow it to get hot enough and open the circuit before the fuse blows. Any suggestions? Thanks.

Ivan for Model Number Kenmore Elite electric dryer (MOD: 110.62084101)

ANSWER Ivan, We'll need to start in a nother direction. First, check the blower wheel, make sure it's not loose on the shaft, cracked, brokrn or the vanes aren't clogged. Check and make sure the tumbler seals and the blower seal fit tight against the drum, and blower housing. You may have to use an amp probe meter and check the amperage draw on the heater circuit (20 amps +/- 10%) and should have a resistance of 8.5 to 11.5 ohms. You also want to check to see if there's an amp draw, when the dryer is not running, that would indicate a faulty heat circuit in the motor switch or heater relay. Aws a last resort, you may want to check the wiring and repalce the thermistor 8577274 there is a possibility there.
