Understanding the Problem
When a dryer overheats because of restricted airflow, it creates a dangerous cycle: lint blocks the vent, heat can't escape, the dryer gets hotter, and the thermal safety devices trip to prevent fire. If the safety devices are bypassed or fail, a fire can result. This overheating is specifically caused by exhaust system problems rather than failed heating components.

Helpful Repair Tip
This is a maintenance issue that requires cleaning rather than part replacement in most cases. Clean the lint trap, the inside of the dryer cabinet, and the entire exhaust vent system. If the thermal fuse or high-limit thermostat has already blown from overheating, those parts will need replacement after the airflow issue is resolved.
