Could be your gas valve.
SOURCE: kenmore no flame
Is this the scenario? It lights for a few cycles or maybe not at all. The ignitor glows and goes out but no flame. Comes back on then does the same thing. If so it could be failing coils (those two black cylinders on top of the gas valve assembly). There's a kit that includes both and it's a fairly simple job.
SOURCE: gas comes on and ignites first time and after up
bad gas coils located on top of the gas valve.when the coils are on there way out they will do this,when they heat up they fail,when the dryer and the coils cool down they will fire.they let the gas in and the ignitor ignites the flame after 15 to 30 minutes they fail.let me know how you make out
SOURCE: I have a kenmore gas dryer the igniter glows flame
Hello, welcome to FixYa.
I'll start by saying your post indicates it is obviously a Kenmore gas dryer, however if you could post the complete model number I can speak directly about possible remedies instead of generalizing.
At the risk of doing so, you mentioned you do get heat intermittently, and the drum does turn correct ?
If this is a symptom where the unit at first begins to heat but the flame drops out in a matter of seconds or minutes I would be looking at the burner coils. This is what you'll be looking for...
Once you've gain access to the coils you'll need to remove the wire harness and check the continuity.
Here's the tricky part though...many times they will ohm out ok when cool (not operating) yet as soon as there is current passing through the coil it "opens". The wire inside the coils is so fine that often it only takes a small current to "open" the circuit.
Most times it will only be one coil that fails but it is good practice to replace them both, many places used to sell them in a kit so double check with your supplier. I've attached a link here, though it may be different than your model the principles to changing the coils are the same.
As far as what part you may need and how to get it. There are a couple of places I prefer, on-line at "searspartsdirect.com" or "repairclinic.com".
Kit contains both the two wire and three wire solenoids. One solenoid is the primary and one is the safety. Both have to operate for the gas valve to open. Usually, one of them burns out as I said but you should always replace them as a set.
**unplug the appliance and turn off the gas supply before attempting any service...safety first**
The most common for Kenmore is part number 3479 at "repairclinic" as this link should provide you.

Let me know how you make out or if you require further assistance and I'll do whatever I can. Thank you for your patience while I was away for a while. Good luck.
Regards,
Macmarkus :)
