My friends dryer wont heat and dry the clothes unless she pulls the lint trap out. Do i just need to clean out her lint trap and hose and wall and dryer etc? I fix a lot of things, and this one seems to me that it would be that EVERYTHING probably needs to be vaccumed and brushed out. Since it does heat when the lint trap on top is pulled out, i thought clog seemed to be reasonable. I dont want her to have more lint going throughout the dryer since she drys with the trap pulled out and cause a fire.
