110.76824690 Kenmore Gas Dryer won"t stay hot

[mad4jim]

I have checked thermal fuse and hi limit fuse for continuity.  Both seem to be fine. Dryer starts and starts getting warm , then starts turning cold.  I have cleaned and checked blower behind dryer and outside and getting strong air.  There is also a small rattling noise just before it attempts to ignite.

If it heats a little bit but dies. Then replace the gas valve solenoids. They get hot and quit when they get a little age on em.
