We have a commercial inglis gas dryer..under door is a model number JO-71200 when i search for it says no match.dryer quit about a week ago we replaced a few rollers then we noticed clothes weren't drying...so we cleaned the lint from every partstill didn't dry clothes rightso i came on here and found out we didn't clean the drum were the lint travels up toit was full.i replaced back and pluged it in an now the glow light comes on flame stays lit for about 10 seconds or so then goes out.i kept checking and seen no flame coming on after just the glow light i have tried everything i believe it might be thermostate on blower i looked at it but no way of really telling if its bad...can you tell me what you think it might be? Thanks Gary

Well I'm not familiar with gas delivery systems on dryers, but I can tell you how they work on home heating boilers and I'm sure they are very similar. There are two type, standing pilot (which you have) and spark ignition. Spark ignition uses two electrodes with an electric spark to ignite the gas. Now your situation your dryer may have what is called a thermocouple which is like a little metal cylinder connected to a wire. When the flame is lit it heats that thermocouple which produces a voltage. That voltage keeps your gas valve open to keep the pilot light lit. If your pilot light is lit then the thermocouple is not bad. You need to check your circuit and see where the break is. Its true it could be a thermostat. To check a thermostat you need to take it off the dryer and you can either use a lighter or put it in boiling water till you hear is pop or open up. If you hear it pop twice then it is good (you'll hear it pop once when it heats up and once when it cools down). There is a circuit that keeps that gas valve open, and after 10 seconds something is opening that gas valve circuit, you need to see what all is connected to it, then you will solve your problem.
