IGNITER LIGHTS, nO GAS IS EMITTED. iE. THERE IS NO FLAME

Are you sure the igniter is good? Just because it glows, does not mean it is good. Depending upon the igniter type, it must read a certain current potential to open the gas safety valve in order for gas to flow. The following link explains:

I know the link is for a gas range, but the theory of operation and igniter types are the same. The gas will NOT flow as long as the current potential is not reached. This is a designed safety feature that prevents free flowing gas from entering the dryer cabinet without ignition. With no safety features in place, gas would accumulate and could cause an explosion.

In addition, the number one cause for poor drying is clogged ventilation. A dryer needs proper air flow in order to work efficiently. Cleaning the lint trap is not enough the ensure the dryer is free of lint and debris. Periodic inspection of the vent line (from the dryer to where it exits your home) and dryer interior is recommended. This also causes a potential fire hazard if lint builds up inside the dryer cabinet (especially around a burner assembly).

Bad gas valve solenoids are still a possiblity, but I would recommend checking the igniter first. If the igniter is proven to be good and you wish to replace the solenoids, there are two of them on the burner assembly. One is the MAIN, and the other is the PILOT POSITION. It is highly recommended that you replace BOTH as a set to prevent premature failures.

I hope you find this information helpful. Let me know if you require additional assistance.
