The clean lint screen light keeps blinking on the dryer. It will not come on. What can be the problem? I have cleaned the lint screen and the lint hose and also unpluged the dryer. I am still having the same problem.
Answer Hello Kenneth,
The first suspect is the exhaust duct. I know you said you had checked it, but if it is flexible, this may be the only issue. Check the exhaust for crimps or clogs as this is the most probable cause and the most denied by customers. Remember the duct should be as short and straight as possible while being a full 4 inches for proper air flow. Flexible ducting is insufficient as it has the ridges through the full length which slows the air flow. Plastic pvc piping is insufficient as the interior diameter is only 3 1/2 inches. The only ducting recommended by any of the manufacturers is the 4 inch aluminum dryer duct. For a 90° angle, they make the elbows in the aluminum and you should always duct tape the sections together as screws will catch lint and clog the new duct.
As far as getting the unit going, there is a good chance that the thermal fuse has failed. Keep in mind that the thermal fuse is just that...Thermal. This means that it is opened by temperature. Nothing else can cause its' failure. This means that the exhaust has to be holding too much heat in the unit and must be corrected to prevent a repeat of the same failure. I would provide a part number, but the model number you posted doesn't come up as valid. If you want us to look it up for you, we can do this if you call in or if you re-post.
Be aware also that if the thermal fuse tests good, the issue could also be a failed control board.
