Thank you for your help Rick !!!

Up until recently I never would have guessed the thermal fuse could cause this problem but it can. There's 120 VAC going to the gas valve and it energizes two of the three coils and the igniter. When the heat from the igniter opens the flame switch the current flows to the other coil and gas flows through the valve. You say it ignites for about 10 seconds then shuts off. It sounds like it's losing the voltage to the valve. To see if it's in the gas valve assembly or if the problem is else where set your meter to measure VAC and insert the leads into the back of the connector for the two wires going to the valve. Then start the machine on time dry about 40 minutes and select high heat. Start the dryer and watch the meter. It will show 120 VAC. When the flame turns off and the meter doesn't change, the problem is with the coils or the valve itself. If the meter indicates 0 VAC when it turns off you need to look elsewhere like a thermostat or control. If it does read 0 take the two wires off the thermal fuse and temporarily short them together. Wrap a piece of black tape around them if necessary so it doesn't touch anything and try it again. If it works replace the thermal fuse. DO NOT LEAVE THE THERMAL FUSE BYPASSED TO DRY CLOTHES.
