My gas dryer is not heating

there is no smell of gas so what does that mean

if you changed the gas coils,try tapping the gas valve,sometimes this will get the dryer running and then you know the valve is bad but still change out the valve or it will happen again

Electronic ignition or traditional pilot light situation?

You may have dirt in the burner. If there is a thermocouple, it may be defective. If there is electronic ignition and it is lighting yet the flame goes out, there is a sensor that needs to see heat to keep the gas valve open. It may be dirty or out of adjustment.

Check your owners manual.

Let me know what you discover.

It is not getting gas. Either there is no gas getting to the valve or the two solenoids ontop of the valve are faulty and need to be replaced. The fact that the ignitor glows means the thermo fuse is ok.
