Why does my thermal fuse keep blowing?
It blows once a month or about every 8-10 loads of laundry. If it's not an airflow issue what could it be?
Amanda Schulz there is more to airflow than a vent and exhaust. Always double check the blower wheel/motor to ensure you have proper air for the airflow. Also check the cycling thermostat which can cause the dryer to overheat. We would need your exact make and model for more detailed instructions.
What is the model number of the dryer?
Don't know Samsung but a lot of dryers have a high limit thermostat that should operate to turn off the heater element at a preset maximum high temperature and then turn it on again when the temperature drops to a preset lower temperature again.
The thermal fuse is a safety backup which is designed to prevent a fire from occurring by disconnecting the power, if the thermostats fail. There usually are other temperature sensors as well to detect lower temperatures for different cycle options, delicates etc but there should also be a high limit one."
