Problem: Dryer ignites and works well for about 20 minutes or followed by the igniter cycling on and off with no flame.

Work done: Took dryer and venting completely apart, cleaned, inspected and lubricated where needed. Replaced gas valve coils (part #279834), flame sensor (part #338906) and tried running the dryer with the exhaust duct disconnected, but problem persists.


Question: Read somewhere that the coil resistances should be measured after running the dryer for 15-20 minutes. So below are the resistance measurements for the new coils main, secondary (1/2) and secondary (1/3).

Before running: 1318, 1426, 592
After running ~20 Minutes: 1573, 1666, 677

So the coils would appear to be out of spec slightly before being energized and certainly after being energized for ~20 minutes. But would this cause the problem or is this typical behavior and within an acceptable range due to self-heating?

Although the coils are new, I’m questioning because I also read that a number of people have encountered defective coils (not from any source in particular), new out of the package.

Incidentally, I still have the old coils andthe main coil is open.

Your expert advice is appreciated!

Try another set of coils.

Thanksfor the reply. That was my thought, but how do I know another new set of coilswill not have the same issue? The previous new set came in a sealed FSP package(not from APP mind you ). I guess I just have to take a chance, but it's sofrustrating because if you can't rule out the new parts as the problem, it suremakes troubleshooting challenging!

I'll order the part and report back with results.

Thanks again.

Coils can be hard to troubleshoot to start with.

A lot of times they do not check open like your old one did. They end up failing after they get warmed up and cycle a few times.

From what you have told me if this was something I run into I would go out to my truck, get another set of coils and try it.

Not that easy for you, but if you order them from APP they have a great return policy if they don't do the trick.
