There are a couple things that will go bad to prevent the gas dryer from heating. Alot of times it turns out to be the coils on the gas valve. Check the ignitor, make sure it is glowing orange, If there is not orange glow when you start the dryer then look to replace the ignitor. There should be a plastic plug on the front of your dryer down toward the bottom. Remove the plug, start the dryer, look for the glow inside.
I hope this information gets you started. If you have anymore questions please ask. You can still ask me questions even after you press the accept button.

Your radiant sensor may have failed. This will keep the ignitor from glowing. It sounds like it is already telling the dryer that the burner is on so the ignitor will not glow.
This is the next step I would take. There are other thermostats that will prevent the ignitor from lighting but these are the most common failures.
The radiant sensor is number 48 in the diagram below. I would not worry about having an extra ignitor for your dryer. It is more than likely that you will need to replace this sooner or later. Let me know if you have anymore questions. Please feel free to ask.

Well, next in the chain of command are your thermostats. They cut off the heating system when the dryer is at the proper temperature.
Let's try this. Number 43 on the diagram below is a high limit thermostat. This will shut the heating system off at certain temps. Take the two wires that are going to this thermostat and connect them together. Now start the dryer again, just don't let the ends of the wires touch anything when you plug it back in.
Try this and let me know how you make out. This is the degree of difficulty I was explaining to another customer. Thanks for hanging in there.
We will get to the bottom of this.
Thanks for your patience,
Try the same thing with number 42, it is a thermostat with four wires. Only jump out the two bigger wires. The two small wires cannot be jumped.
Are you talking about the white fuse?
Yeah, it will be ok in the meantime. I would double check the venting of the dryer. This fuse usually goes when there is a venting issue.
Check the vents first before running the dryer for any long period of time. If the vents are ok, then it should be ok to run for a few days.
