110.74812200 80 Series Gas Dryer Not heating

I had the same problem a year ago and replaced the coils.

I started throwing parts at it:
1. Non resettable thermal fuse(didn't change anything)
2. new coils(didn't change).

Now I am stuck.. i keep reading about to look for a glow but my dryer in order to see the glow it would be impossible since the entire from panel comes off and the drum attaches to it.

Any ideas?
