Dryer flame issue

I am having similar issues. Sometimes, I get flame, but later it flames out and dryer runs cool (for hours). Sometimes, it won't make fire on start up. Ignitor will glow for about 6 seconds, and then stop glowing and not ignite the gas. I saw in an earlier post that there should be continuity between all coil contacts, both the two and the three pin coils. I have no continuity between any of them. Someone also mentioned testing them against a specification. What is that spec?

My measurements: 3-pin coil (I am calling pin 1 the one closest to the dryer front), 1.4 Kohms: 1 to 2, 570 ohms: 1 to 3, 2.0 Kohms 2 to 3.
2-pin coil: 1.3 Kohms.

Thanks

Thanks Mitch.

I order a pair of solendoid coils, considering them to be the most likely source of trouble. If anyone knows the proper resistance between leads on the two and three pin solenoids, that would be helpful.

 

The resistance won't mater coils open up after they heat up and will not relight until shut off for a while. Your readings look about right don't have spects here.

 

I struggled through a couple of dryer loads this weekend. The dryer lights properly at the beginning of the load. At some point, the thermostat cuts off the flame, which I think is normal. Thereafter, it fails to relight, though it continues to make attempts. The ignitor will glow for about six seconds, fail to light, and go dark. I measured continuity (low resistance) on the ignitor, which seems normal. I once replaced an ignitor on a gas stove, and learned that even though they glow, they can be bad.

Once the dryer flames out, I stop the drum turning, and let it cool for a few minutes. The dryer will light when started and run well until the flame is extinguished the first time. I should have a new pair of coils to try by Wednesday. I got them new for $7 on ebay (including shipping). They appear to be easy to replace, so it should be a quick and cheap solution to try. I will let you know if it works.

 

Installed the new gas valve solenoid coils, which was about a ten minute job, and all is well again. I got the coils new on ebay for about $8, including the shipping.

And, I got my venting all cleaned out, which is really needed.
