Question about Dryers
The burner ignites during the initial start. Then, after cycling off, it fails to re-ignite. The igniter doesn't stay on long enough for the gas valve to open (~6 seconds) and the burner fails to ignite. I have replaced the Thermal Sensor but it did not resolve the problem.
The following link explains a little theory about glow bar style igniters:
I know the link is for replacing an igniter on a gas range, but the types of igniters used and the theory of operation is still the same. First, you will need to determine if your igniter is still good. The link provides you with the tolerances you need. If the igniter is still good, I would recommend replacing the gas valve solenoids (coils). There are two of them on the burner assembly near the igniter. One is a two terminal, the other is a three terminal. One coil is the gas main, the other is the pilot position. Typically, a weak or bad igniter will not allow the burner to ignite at all. If the coils are bad, however, they may allow initial ignition, but once the burner assembly gets hot, they may shut off. I've seen this happen before. Test your igniter just to be sure, but I'm leaning towards the coils being faulty. It is strongly recommended that you replace BOTH coils at the same time if one or the other is defective. They are generally sold as a set. If you post back with your COMPLETE model number I can assist you in trying to locate replacement parts if you like. I hope this information helps you. Let me know if you require additional assistance.
