Understanding the Problem
The high-limit thermostat is a safety device that cuts power to the heating element if the dryer reaches a dangerously high temperature. Unlike the thermal fuse, many high-limit thermostats reset automatically. If yours keeps tripping, the dryer is repeatedly reaching unsafe temperatures. The root cause is usually restricted airflow, a failed cycling thermostat, or a grounded heating element.

Helpful Repair Tip
The high-limit thermostat tripping is a symptom, not the root problem. Clean the exhaust vent and lint trap thoroughly. Then check the cycling thermostat — it's supposed to regulate temperature and prevent the high-limit from ever needing to trip. A failed cycling thermostat causes the heating element to run too long, triggering the high-limit safety.
