Dryer not heating

After searching on here, I decided to just replace the 3-components listed on this site (not the heating element wire kit). I didn't test the heating element and would save that for last if the replacement parts didn't work. Off the bat the fuse was the problem - no resistence reading on my $6 multimeter like the new one. I didn't bother testing the other components. Since I wasn't sure why the fuse blew I decided to replace the Cycling and High Limit Thermostat at the same time to be safe. It took me longer to move the unit to access the back panel and take off the dozen or so screws then it did to replace the 3 components. The cost of the parts with shipping was less than the trip and diagnostic charge from an appliance repairman.
