When you had it disconnected from the vent did you run a load.

Unplug the unit and disconnect it from the vent system.
Now try a run.
If it now dries OK odds are the vent system needs checking/cleaning.
Be sure to check that the louvers on the outside of the house open correctly.

If you do not want any lint in the house.
Take a pair of pantyhose.
Put one leg into the other and then attach this to the dryer’s vent.
Leave enough room so the pantyhose can balloon out like a windsock.

Both the above will let you check the temperature and the air flow.

Note: The above is not recommended for gas dryers due to carbon monoxide concerns.

If is is not drying with the unit off the vent.
Check the lint filter. Sometimes they can get coated with fabric softener residue greatly reducing the air flow. Also check the holes at the back of the drum.

Check that the vents at the back of the unit are clear.

Check/clean the blower wheel.

It’s also fairly common for that style of dryer with the in door lint trap to have a large amount of lint, dirt, etc build up in the area that receives the lint screen and block air flow, causing the symptoms that you described. You may be able to remove the lint trap and stick a thin vacuum attachment down in there to suck all that junk out.
