I have a ruud furnace that wont stay running. The unit goes through
the start up cycle. The electronic igniter will start sparking, and
the flame will ignite. It will run good for about *5-7 seconds, then
it *it will go out like the unit cut the gas off. I think it is a
flame sensor, but I am not sure what it is called.

This furnase has a circuit board with 3 leds. two are green and one is
yellow. It says Flame. This light flashes, but the other two stay
solid green. I cant find a manual to see how to read these. Any help
or pointers would be appreciated.

I know the file name says "Rgph" but when you examine the file, it is
the 40 page installation manual for GPH models as well. *Might match
your furnace, or be close enough to be helpful.

Thanks!!! I was searching for this installation manual and couldn't
find it.
