I am guessing this is a common problem, hopefully with an equally common solution.

One of my "exhaust diverter valves" (not sure what it is really called) will open but not close back up. I can close it by hand but the motor is binding up and it won't go automatically.

I am going to take a much closer looking tomorrow. I may just need to clean some gunk out or even get a new motor. Anyone with experience with this issue?

check for an air leak before you rip into it. Mine was a tiny hole in one of the air lines.

Air lines? Mine is an electric solenoid that opens and closes it ... isn't it?

I didn't look at it for more than a couple seconds. It being 9,000 degrees and all

ooops..mine was a silent choice.... not sure what yours is... sorry

On the one I have with electric lightning they are always stiff at the beginning of the year. I just manually move them in and out several times and they work after that. Sometimes they stick so hard they blow the breaker.

this is it ... or very close

Wd-40

Both of mine wouldn't move, WD 40 fixed one but the other is frozen, just going to order new actuators this week, that will solve it.
