Replacing the thermal fuse on your dryer is a fairly simple and inexpensive appliance repair.  The fuse  is a few dollars at the local appliance parts house and you can pick one up and have it changed in under thirty minutes.

In order to change the thermal fuse you will need go gain access to the rear panel.  Pull your dryer forward and with a ¼ inch nut driver remove the screws around the outside edge of the dryer’s back panel. Once the panel is off you will see the heating element assembly on the right and blower housing on the left. The thermal fuse is located between the two on the lower left. The thermal fuse will normally have two blue wires that connect to the spade terminals built into it.  There is one ¼ inch screw that holds the thermal fuse to the back of the dryer and when removed the fuse will slide out of the housing.

Install the new fuse back into position on the rear of the dryer and hook the wires back up. After reinstalling the back panel take extra precaution not to kink the dryer vent. If you do the fuse may trip again.

When the lower thermal fuse goes bad this is an indication that you have an air flow restriction or grounded heating element.  One of the two more than likely caused the fuse to go bad.  You will need to properly identify the original problem or the fuse will trip again and the appliance parts house may not take the fuse back.
