Perplexing problem

It sounds like there may be gas comming out of the jet before the ignighter is working. That would account for the fire going into the tumbler. Sounds like it needs to be taken care of fast. Go around back while it is running and keep an eye on the ignighter and the fire for 10 minutes or so and that should give you a good idea of whats going on. Just be carful gas can be very nasty stuff. Good luck

My dryer has a spark ignitor not a glow plug does that make a difference in what you suggest?

I have an older SQ 30# dryer that is scorching clothes. I have changed the thermister (thermostat), the high temperature cut off, the computer, the gas valve and cleaned the gas fire log...it is still burning clothes. The next step my distributor recomended is to slowly close the gas cock to see if that reduces the flame. It appears the flame is too long and occasionally leaping into the tumbler causing the scorching the temperature is fine. Any ideas?
Thanks, Dave

No not really, I would still eye ball it while it is starting. Check the gap on the starter. Maybe the spark is not making the jump sometimes. Also check all electric connections.

If they are older dryers they probely don't have built in gas regulators (in the gas valves) you need to buy some add on regulators that are set to the WC( water inches columes) of gas that the dryers require. Look in your manuel for the max WCs your dryers require and buy the regulators to match. They are ajustable and you can buy a gas presure tester to adjust to specs.The tester is a long tube that you fill with water and attach to your gas valve, If you don't fill comfortable doing this get a plumber or call your gas company for help.

Thanks for all of your ideas, just a quick update. I cut back on the gas regulator to between 3 and 3 1/2 lbs and still sorched some towels. Changed the thermister AGAIN and it seemed to fix the problem. At least I haven't been able to toast any marshmellows over the clothes lately. The thing that annoys me about this process is that the entire time the SQ computer (changed 3 times) continued to tell me the temperature inside the dryer was fine even after cutting back on the gas flow at the regulator and watching to see that no flames were coming close to the tumbler. So I guess the moral of this story is don't believe the computer readout on your SQ dryer computers.
Again, thanks for your help

I once had a similarly intractable problem with dryers scorching the loads. The problem turned out to be lack of weather stripping in the lint compartment door. Cool room air entered and kept the thermister below the shutoff temp.
