Looking for advice on servicing my heater. It's flaming out of the combustion chamber right under the rollout switch. When I took over the unit was full of tree debris, I took the covers off and extensively cleaned it out. I also replaced the thermostat housing on the header as it was leaking. The unit is a bit dirty from cleaning neglect but inside it looks unused beside the flame out - The combustion chamber has zero soot - I've shined a light up and down it and looks very clean (shiny burners and very clean firebox). After cleaning out all the debris it still flames out. It seems the next step is the removal of the gas hardline and pulling out the burner tray to inspect everything. I'm not sure I can do this without also unhooking the exchange plumbing and moving the entire unit. Wondering if anyone has suggestions of things to try before I disassemble further? (or have someone else do this for me).
This video isn't the greatest example - it usually lights normally then starts flaming out a min or two in. This video was taken on the 3rd attempt.
