Question about Dryers
The dryer go throught cycle but no heat. if it is the pilot light why would it go off and where is it located of the machine
Your dryer does not have a pilot. The dryer has an igniter on the burner assembly. When you push the start button, the igniter begins to glow. Once it reaches a certain current potential, the gas valve is opened, gas flows and you have ignition. This is a a built in safety feature of the burner assembly that prevents free flow of gas without ignition. Without it, you could have a build up of gas inside the dryer cabinet followed by the loud "phoooom!' of an explosion when it finally DOES ignite. More commonly the igniter either fails to where it does not glow, or becomes weak and will not produce the required current to open the gas valve. The following link explains a little theory about glow bar type igniters and what their current potential should be:
I know the link is for a gas range, but the igniters in some of these appliances are identical and the theory is the same.
Another cause of an ignition failure are bad gas valve coils. There are two of them on your burner assembly. It is recommended that if one fails, you replace BOTH of them at the same time. If you go to searspartsdirect.com and type in the model number you provided, there's an excellent exploded view diagram of your burner assembly and parts. The igniter is listed as item number 4 (part #279311) and the safety valve coils are items number 13 (part #694540) and item 14 (694539).
If you can view inside your dryer under the drum, you should see an orange glow as the igniter comes on. If you do not see the glow, or if the igniter glows and there's no ignition after 90 seconds, I would recommend replacing the igniter. If the dryer ignites, then shuts off after a short period of time and will not reignite, you may have a bad coil (you may hear a rattling sound too).
I hope you find this information helpful. Let me know if you require additional assistance.
