The All = Knobs,timer,wiring,motor,vents and is clean.
It takes 3-4 times to dry 1 load?
Yes the heating elelemint gets hot. Is there a thermostat switch to keep it on longer?:)

The operating (cycling) thermostat (Item 8 in Section 3) controls the temperature.
Note: It has a built in heater which when turned on lowers the units temperature, causes it to cycle more often.

Undo the dryer from the exhaust
Run a load
If the load dries correctly then you have a vent problem.
Clean/check the vent system. Make sure the outside louvers open fully.

If you do not want lint in the house.
Take a pair of pantyhose, put one leg into the other and attach this to the dryer exhaust.
Leave enough room behind the dryer so it can blow out like a windsock.
Run a load.

Both the above will allow you to check the air flow and temp.
Also the above is NOT recommended for a gas dryer due to possible carbon monoxide problems
