Wirlpool dryer

Dryer is not completly drying clothes. It look like the heating element does not stay on long enough in the cycle to dry, seems to cut out too early. What do I replace, heat sensor or something else:confused:

The first thing I would do is to take the dryer apart from the front and from the back and clean it. Especially the air duct on the back (#1 on the bulkhead break down diagram) and the blower wheel (#10 on the same break down diagram). Lubricate all drum support rollers (#44 on the same break down diagram).

Assemble the dryer back, disconnect the vent hose from the dryer and run one or two loads. Reconnect the vent hose and run the dryer again.
If without the hose it works better then the vent inside walls is clogged and needs cleaning.

Post your findings, please.
