Dryer was taking twice as long to dry as it used to.

Took of the back cover, and removed the vent connecting the blower motor to the drum. It was completly full of lint, so cleaned it out completly, and tried the dryer again. The heater element was still cutting off early, and the clothes were not getting very warm, but better than before. Decided to change the thermal cut-off switches. Ordered the parts on Sun, they came in on Tuesday. Dryer was up and running Tuesday night. Just 2 screws per switch, took less than 1/2 hour. The dryer now runs like brand new, and my wife was ready to fork over $800 for a new one!
