Dryer was working normally before move to new apartment. Before hooking up to wall husband wanted to make sure line was clear and had pulled out harden lint where he could reach in wall. Attached dryer hose (dryer is very close to wall in order to close the doors), made sure hose wasn't kinked despite being slightly misaligned. Dryer again takes forever to dry clothes, lint only attaches on bottom of lint screen but also sporadically on the opposite side. Enter maintenance to dry and clear line to roof. Re-attach dryer, same problem. Another maintenance call and this time he has a blower and drill with brush to make sure line is clear. We pulled dryer out afterward so that venting hose would be straight to make sure it wasn't the way the hose positioned after pushing dryer back, same problem. Did two checks, with the lint screen removed from the top--put paper on top while dryer hooked up to wall, paper blows up. Second check with dryer unhooked from wall, paper sucks inward. This dryer unfortunately is just shy of 3 years old. Maintenance is stating someone else in complex had same problem and is telling us the blower on our dryer isn't strong enough to push = our dryer is the problem. Husband did take back off to make sure no lint accumlated, nothing. Any idea's? Thank you!!
