Hi, I have an RUUD Silhouette II, model UGPH-10EBRJR. I also have the serial number if that's needed. Anyway, the issue that I'm having is that there's no heat. The AC works, as does the neutral fan. However, when I turn on the heat, the furnace will run for around 2 minutes then turn off. After it turns off, my thermostat (Honeywell RTH230B) still displays a small flame, indicating that the heat is on. I've tried turning the switch on and off several times but, there's still no flame coming from the burners.When I check the board, the light that says "Flame" isn't lit up, but the two lights next to it (OK/PWR) are. I'm really not sure what to do next.. Any help would be greatly appreciated.

Remove all power from the furnace, it is likely the brain in the furnace is need of being reset, from the battery replacement, why did you change the battery, was there an indicator telling you to change it?

Many times just removing all the power to the furnace will do the trick with a reset, if not let me know and we will go from there, but it sounds like the main brain is confused or bad, more likely confused, so try the power removed first.

If the burners do not fully ignite, the sensor will shut the furnace down. The lack of sufficient burner flame is a gas valve or gas pressure problem within the valve.
Replacing the gas valve with the original one may get you going. I surely suggest a professional service company for safety reasons and a thorough inspection. A 20 year old furnace is past it's normal life span.

SOURCE: gas furnace, main burner ignites the other 2 don't. then shutdn.

Between the burners is a small rail in the pressed steel where the flame runs across to light the other burners and it sounds like there is dirt or debris in the step over rails causing the problem. You will need to use some compressed air on those rails to clear them out. Once the rails are clear the other two burners should ignite right away.

Make sure filters are clean . if they are stopped up the unit will over heat. Lets start there. Russ
