Dryer not drying clothes

Clothes Don’t Dry Properly. The Machine Stays In Sensing Instead Of Going To Wet. Then It Comes Up With E1 Code After 20 Minutes. We Have Replaced The High Limit Thermostat And The Thermal Cut-off. Still Have The Same Problem. Can Anyone Help Us? Sometimes It Takes Three Tries Before Clothes Will Dry.

Start the dryer and go outside to the dryer vent, you should feel a strong flow of air, if not either the dryer vent behind the dryer is clogged or kinked, or the house vent is cloged
