In any case yes the coils are the next thing if you checked airflow and the operating thermostat didn’t correct the problem. I am going to try to find a wiring diagram to see about other possibilities.

Yes the timer will not turn unless there is heat.
Did you check airflow as Gene suggested? The very first time with the new thermosostat it ran the flame for a minute or so and now it just is back to the original problem.

I didn’t have far to look there was one on the parts breakdown. You got the high-limit switch, which is unlikely, an intermitting problem generally if they are bad you will not get heat at all. If you are not getting any heat at all now check the high-limit. Bad high-limits are normally caused by poor airflow. If it checks ok I am back to the coils. Check out this page Gas Dryer Not Heating

I'll update on Thursday whether or not the flame is still coming on.

I won’t have time to respond anymore today so.
A weak hi-limit can cause this.
Weak coils can cause this but like I said typically they won’t cycle until they cool down.
If the dryer is connected to LP and set for natural gas the flame will be too big and would cause it to quickly overheat and cut off. I am not sure if this is even a possibility but its just a thought .
Poor airflow can cause it to quickly over heat as we have already said.
These are the only things that I know of that will cause your problem. If I think of anything else I will let you know. Post what you find.

So now it seems the flame comes on for a few minutes and then goes out, but never tries to get going again.

Alright, thanks for the help so far. I'm going to try to work with the coils Saturday.

I think it turned out to be the coils. I just got finished putting a load of clothes in and it came out nice and warm! Thanks applianceman for helping out! I'll definitely be returning here for more future projects. I've actually got a dishwasher that doesn't work which I may work on sometime in the near future.

Hi, I get the same symptoms. I've tried most of the suggestions I've seen online, i.e. replaced solenoid coils, flame sensor, cycling thermostat, and hi-limit thermostat. I've also cleaned the exhaust, removed the exhaust tubing, cleaned out the air flow. So, at this point, I am out of ideas.
Here are the symptoms:
1. I would start the dryer using timed dry (30 mins) and regular heat.
2. The ignitor will glow
3. In a few seconds, it would click, and the flame will go on
4. In about 5 seconds, the flame would go off
5. In about 20 seconds, the ignitor would glow again, and flame would go on in few seconds
6. Then flame would go off again in about 5 seconds.
7. I think it cycles ---flame would go on and off --- until it finishes
Any help is appreciated.
Thanks
