DRYER HI LIMIT THERMOSTAT SHUTS OFF==NOT A VENT PROBLEM

[aaroneis]

With thanks from the begining,

I have a maytag gas dryer and the flame keeps cutting off after 15 seconds after the first ignition, and then less than that on successive times (I'm sure it didn't cool down yet, so it takes less time to cut out).

The exhaust ventilation is fine.

One googler had an idea that if the flame wasn't starting out down the venturi far enough, then the flame would contact the hi limit stat and trigger it prematurely.

The other thing is that I don't have a blue flame, it's bright yellow, and it seems to be shooting out pretty strongly.

Is there a way to adjust the flame so it comes out blue, not yellow? Is there a way to make the flame start out past the hi limit stat? and what to do about the premature cutoff of the hi limi stat? If I buy a new one for twenty bucks, and the problem isn't the stat, but is the flame, I'm gonna be upset.

thanks again!

Are you sure? That's the usual culprit.

That doesn't sound right. Probably it's not adequate to satisfy the flame sensor, which would account for the shutoff.

Perhaps there's an obstruction in the jet?

First, thanks for the reply.

I removed the hi limit stat, and connected the wires directly (the ones that were connected to the stat). The dryer works fine (of course, too hot). So I guess the stat was the problem.

Unless when I put the new one in, the problem returns. I'll update when I get the new stat, unless someone has some better ideas!
