My dryer's igniter would glow red, the flame will burn for about 30 seconds and then turn off. I changed the igniter assembly first. Didn't resolve the problem. I then changed both gas coils. It didn't solve the problem, until I put the door and panel back on. The dryer worked perfectly for 3 months, but now it broke down again. The igniter does not glow at all, and the gas does not sound like it is activated at all. What part may I need to replace?
ANSWER Chris, If the glow bar doesn't glow, it wont activate and release the gas at the valve. So your first check should be at the igniter itself [AP3109449} check and make sure the igniter isn't cracked or broken, and you can read a resistance reading if tested with a meter. Then check the flame sensor 338906 mounted on the side of the burner cone, it should have a "closed" circuit at room temperature. If all checks OK, you'll need to check all the thermostats for a "closed" circuit at room temperature. If a thermostat circuit is "open" at room temperature, then there is no power to the gas valve and ignition system.
