Trouble shooting manual for Model# RGUJ-05EA-ER RHEEM GAS FURNACE
I need a Trouble shooting manual for Model# RGUJ-05EA-ER RHEEM electric ignition GAS FURNACE.
Igniter turns red hot but the Gas Valve just shakes and makes a clicking sound and then the ignitor will go out.
Furnace does not fire up and fan does not kick in.
Gas valve is Honeywell Part# VR8205A 2008 reg 3.5 ADJ 3-5 Range 24V 60HZ total current .5 A uses class 2 transformer.
I also do not see any type of control board with a digital read out flashing any error code. Please Help.

check to see if the hot surface igniter is coming on or if direct spark see if it is sparking to light if this is working then you are not getting gas from your gas valve. The board should be giving you code by blinking light. If you will count the blinks there should be a chart on the door to tell you what it means. HOPE THIS HELPS
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.
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.
Try cleaning the flame sensor. It is located right besides the last burner. Looks like a thick piece of wire. Take steel wool and gently remove the carbon that has built up. Should only take 4 or 5 strokes. Let me know how it goes after that. ken
