The dryer was running but not heating at all. I always first unplug the dryer from the wall outlet and then ohm test the thermal fuse, which I did and it was good. Then I disconnected the flame sensor and ohm test that, its located on the side of the burner tube, and that ohm test bad, no continuity going through it.

I replaced the flame sensor and it started heating and worked great!

Here’s the flame sensor for this model:
