From a cold start, my gas dryer will ignite. It will cycle 3 or 4 times. In other words, the ignitor heats up and the flame will start, burn for awhile, turn off and stay off for awhile, then the ignitor will glow again, starting the flame. After the 3rd or 4th cycle the ignitor glows, but the flame does not come on. If I turn off the dryer and let it cool for about 20 minutes the flame will come on again and go through another 3 or 4 cycles before it fails. Air flow seens very good. It seems like one of the sensors is faulty, but which one? Thanks
Answer Hello Cris. Sounds like you have a coil 279834 on the safety valve failing. This kit includes both coils. You see, when the coil heats up, the resistance increases and prevents the opening of the gas valve. If it were a thermostat, the ignitor wouldn't glow. I hope this solves your problem and have a great day!
What should I be seeing for exhaust and heat tube temperatures.? The wifey seems to believe that our's runs too hot. And now the thermal fuse has opened? I have procrastinated as far as I can . ha ha
Answer Hi Chris. You should regulate normally between 125-145/150°. It sounds like the venting system is clogged or kinked. You will need to check the vent and clean it out. Be sure and clean the vent pipe and the dryer air duct assembly. If the air flow is not good, the unit will retain moist air causing the clothes not to dry. Try running the unit with the vent unhooked from the back of the dryer and see if the dryer works properly. Clean the vent hood / door flap outside also. The thermal fuse is part # 3390719. The flame senser is part # 338906, they will get sticky with plugged venting and cause the issue you explained. Thank you.
