Rudd Model= UGAA-10EC, Serial #=TN3D104 M2779 3228
Electronic Ignition Furnace (Spark)
Problem: Originally, the pilot light worked but the main burners would not
light. I cleaned the Flame Sensor tip with some light sand paper. Now, the
main burners will light but they quickly shut off after about 10-30 secs.
If I hold a long-stick candle lighter to the Flame sensor when the main
burner lights I can get the sensor hot enought to keep the furnace going for
a several minutes.
OK, so bad sensor and/or weak flame? Does the sensor need to be glowing red
hot? The flame looks ok to me, but a Tech I called who is out of state said
the gas company is putting something in the gas that is clogging up the
furnaces. My problem just started last night. I'm thinking about removing
the small gas line from the controller to the pilot-light point and clean it
out from end to end. Next step replace the sensor (Automatic Pilot E1 Type
3098-136). I was also wondering if this has a gas filter I could change?
The GAS controller has several numbers on it 7921 E11, also has Model
36c84, type 220, 24v 60hz, max pr 1/2 psi, filter cap 2cfh air.
Thanks for your time.
Cheers,
Jim

Seriously... please call a qualified HVAC tech to come out, correctly
diagnose and repair your furnace.
Messing around with a gas appliance is NOT for an individual that ISN'T
properly trained to do so.
(and don't try to tell me that you are qualified... I can tell by your post
that you ARE NOT)

Your welcome. Anytime.
Replace everything, one at a time, starting with the thermostat first.
When it works, you've figured it out.
