SOURCE: Ruud achiever 90 plus gas furnace

I have 2 Ruud Achiever 90 Plus UGRK's. Units were install in 2004. One unit flames' out after ignition just prior to the fan kicking in. Confirmed gas value is functional by switching valves. Check wire connections. Could it be the remote sensor or another 24 volt sensor at the IFC that locks out the gas valve?

Your furnace probably has electronic ignition. Remove the panel that you have access to the burners, valve, electronic module. There should be a main power switch installed on the furnace. Turn it off. Set your t-stat on high. Turn on the power switch. After the unit purges (about 30 seconds) you should see an orange glow at the burner orifice. If not, Turn off the power & remove the heater and inspect it for cracks. (Or use an ohm meter) If open, replace it. Very common problem. If the igniter is of the sparking variety, you need to change the circuit board. Most of the furnaces, there is d diagnostic code chart and an LED on the board. Follow the chart.

SOURCE: How do I clean the flame sensor rod for a Ruud

disconnect the power. the flame rod is located at the end of the last burner. Gently remove it from its cradle and use a pencil eraser or a piece of scotch brite pad. If it doesnt allow the gas valve to stay opened after that, you should replace it

Sounds like a flame rod issue or the flame is not getting to it in time. The flame rod is located either far right or far left in the burner box and has only one wire going to it. It should be in line with the flame on a burner. The computer allows only a second or two for the all burners to lite and to get to the flame rod. Check the flame travel from burner to burner. You may have to clean the burners, the flame tray to each burner and the flame rod. Also check any electrical connection at the flame rod, circuit board and the grounds to the furnace cabinet.

My Ruud silhouette 2 furnace, fan will not come on. If I go and remove bottom cover and replace, the heater will work, until later, when I have to go remove the cover and replace it again.

You need to clean the flame sensor. Follow the orange wire on the left side of burner, remove with a long 1/4" nut driver (magnetic for reinstalling) the take some Emory cloth or fine sand paper, and reinstall. Should work now!

Problem could be the thermostat setting in "fan on" mode. Thermostat could be shorted between Y,R and G. Fan relay points soldered together or main board shorted.

Need furnace model number. It sounds like you're looking for a standing pilot. Your furnace might not have one. Very likely to have a spark ignition type system or hot surface igniter.

Ruud Silhouette II Fails to Ignite

sounds like you have bad flame sensor or the sensor is in a bad postition. To get eliminate the lockout turn the power off to the unit and back on again. Look at the circuit board light and see what the troubleshooting code is.
