Suburban Furnace Troubles.
Suburban SF30-F furnace. First time I used it, everything worked A-OK. After that, it has been hit or miss. Sometimes it works first time, and every time after. Next time, I have to toggle the thermos...

I am pretty sure I found the cause of the furnace problems. I got what I needed to pull the burner out of the heat exchanger. A new gasket and a new electrode. I made a wrench to remove the gas line from the solenoid. The gas orifice appeared to be about 80% plugged with foreign matter. I cleaned it out, and getting ready to vacuum out the area of the burner of bug carcasses and residue. The electrode was greenish with built up stuff on it. Then I will make some mods to the wires for ease of assembly. Then put it all back together and give it a test run.
