Noisy when after running awhile, and overheating.

Cause 1

Heating Element

The heating element warms the air before the air enters the dryer drum. If the element is partially shorted out, it may produce heat continuously, even if the dryer has reached the proper temperature. When this happens, the dryer gets too hot. To determine if the heating element is at fault, use a multimeter to test each terminal for continuity to the case. If the heating element has continuity to the case, it is shorted out. If the heating element is shorted out, replace it.

Cause 2

Heating Element Assembly

The heating element warms air as it passes over the element. If the element is partially shorted out, it may produce heat continuously, even if the dryer has reached the proper temperature. When this happens, the dryer gets too hot. To determine if the heating element is at fault, first use a multimeter to test the heating element for continuity. If the heating element does not have continuity, replace it. Next, test for continuity from each terminal to the case. If the heating element has continuity to the case, it is shorted out. If the heating element is shorted out, replace it.

Cause 3

Air Flow Problem

If the vent is clogged or partially clogged, it will restrict the airflow through the dryer, substantially increasing the drying time. To ensure proper dryer performance, you should clean your dryer’s venting system at least once per year.
