Dryer blows limit fuses, have replaced bef...

The vast majority of dryers that blow high limit fuses have the same problem: Lack of airflow. If anywhere in the venting system for your dryer is restricted your dryer will heat up too hot. The excessive lint in the filter, a clogged dryer vent hose, the vent within the house, even within the dryer itself all are places where a restriction could occur. Check all of these for being restricted. Also make sure if you have a flexible hose between the dryer itself and your dryer vent on your home, make sure it is not crushed when the dryer is in place. This will cause your limiting fuse to blow very quickly.

When you remove the hose from the back of the dryer you can check that the dryer itself has decent airflow by starting the dryer on the fluff/no heat setting. This will give you an idea whether it is restricted inside the dryer or not. If you even have a hint that it is not putting out the air it should, have it cleaned (or if you are mechanically inclined do it yourself just make sure the dryer is unplugged).

Then have the dryer vent system cleaned. Replace your high limit fuse and you should be back in business.
