An air flow restrictions resulting in longer drying times, hotter dryer surfaces and in extreme cases causing the thermal limiter to open on electric dryers.

Restrictions can occur any places in the air flow system, but the most common are:

1. Installing the laundry center in a small enclosed area; such as a closet without a louvered door, that reduces the intake air.

2. Fan problems caused by either a slow running motor, a broken or deformed blower wheel or a deformed fan housing.

3. A lint restriction in the lint screen area.

4. A restriction in the exhaust system in the house caused by the design of the vent, such as: the diameter of the vent pipe being too small, too long or too many angles, a collapsed or lint restricted vent pipe.
