Lint trap only partially covered
Seems my dryer is taking a long time to dry clothes. I had appliance guys out and they cleaned out the vent hose/line which was plugged up. But still having the problem. Also, when I dry the dryer's vent screen/trap only has lint on one corner rather than the whole thing. Makes me think there could be a blockage inside the dryer itself. No error lights/codes.
I'd test it out with something that you know create lint (like some towels). If the filter is not accumulating lint, check the exhaust to see if you are getting an air flow out of it. Disconnect the main exhaust hose to see if you are getting a flow out of it. The repair guy may not have gotten the line clean or you may have dislodged additional lint blockage.
