Lennox Furnace - potential condensation issue??? Maybe?
Folks:
Easiest to watch my 1 min. Youtube I took of the furnace (see bottom of thread). Bottom line is I think I've had some condensation flow back into my furnace--but maybe it was so long ago I shouldn't worry about it?
I run a Lennox EL296UH090XV60C 96% AFUE 2 stage 90,000 Btuh furnace. No water issues; no error codes, etc. However, I've found evidence of water in the past coming in or around the exhaust section.
I opened the condensation trap clean out side and water flowed just fine. My video shows some water stains but they look to be super old. Just not sure what would cause that lower stain on the right side of the furnace. Maybe just a back plug at that end?
Once again, it's in heat mode and runs every day and I see NO water anywhere. These stains are for past water, obviously. Furnace, right now, runs happy with no issues.

It is common for the condensate drain line to clog. You mentioned cleaning the trap but did you also check the rest of the line to make sure it's clear?

So I was able to check the pvc pipes outside of the furnace, I don't understand the interior parts. Meaning I can see the drain line that goes to the left side and I can pull that off and check it, but not sure about the long, black thin box-like part. It has the plugged part on the right side that dripped rust color. Not sure how to inspect or clean any of that out.
