Sencing light on the dryer (by 3 users)

The thermal fuse is the most common problem that can cause this. If you remove your bottom panel (2 1/4 inch screws) and then your lint duct (the area where your lint screen sits) you will see a white peice of plastic with 2 blue wires going to it behind the lint duct. That is your thermal fuse. A continuity meter can quickly be used to check to see if it is bad. If it is bad, replace it and re-install your lint duct then run you dryer on air dry (if you run it with heat, you could burn your replacment fuse out). Then go to the vent on the outside of your house. You should be able to feel a good deal of air pressure on your hand. If not, check the hose behind your dryer for kinks or being crushed (not uncommon even on "professional" instalations. If that is ok, you will need a cleaning for the house part of your vent.
