Dryer Thermal Fuse Keeps Blowing
The dryer has 2 thermistors, one near the heater element. One failure mode, if you have bad seals (they do wear out with age) on the blower or filter cover, such that colder air is sucked into the system, giving that thermistor a lower reading than actual, the control system will keep adding heat to bring up the temp. But, actual temp get hotter and blows the thermal fuse. Replace or repair blower and dryer filter cover seals.
