no heat unit ran well otherwise

Dryer ran but no heat. 1st thing I assumed was a bad glow plug. Mistake, after 2 hrs taking apart the front of the dryer(Drum,Belt,Whole front) and tested the voltage to glow plug was 0. I went to parts select and determined that the thermal fuse was bad. Replaced it along with the t-stat and over-limit switch. Worked great! Next time I will go to this web site BEFORE I assume anything. whole repair was less then $60.00 Very fast shipping and 2 weeks later the dryer is still working. Advice to everyone, replace all 3 items to play it safe not just the thermal fuse!
