Thanks for everyones input.

The valve is actually a White Rodgers, and ironically the only place
in my area that has one in stock is the Trane parts warehouse about
1/2 hour where I live, and pretty reasonable at $65. So I might just
get it , along with an igniter as a backup, just to give me piece of
mind if the valve decides to crap out altogether. With the holiday
weekend coming, and cold temps on the way, the last thing I need to do
is scramble around finding parts.
