Understanding the Problem
Some heat cycling is normal — dryers turn the heating element on and off to maintain temperature. But if the dryer cycles too frequently, takes long pauses between heating, or clothes aren't drying because heat is off too much, the cycling thermostat, high-limit thermostat, or heating element may be failing. A restricted vent can also cause excessive cycling.

Helpful Repair Tip
If the dryer heats briefly then stays cool for long periods, the high-limit thermostat may be tripping due to poor airflow. Clean the exhaust vent thoroughly. If cycling is erratic even with good airflow, the cycling thermostat is likely failing and needs replacement.
