I cleaned mine out, and PRESTO! No problems now. I am a complete noob when it comes to HVAC...got real lucky I guess.
You mean your furnace caught a "cold" and had drainage problems? -WOW!
I never noticed a gurgle but that doesn't mean it's not the problem. I had the thing off when I disassembled and cleaned up all the parts near the blower but never checked that for a clog. I had a carrier that shut down years ago due to a clogged hose. It was like salt in a cooking show--just a little pinch will do it.
I hope that's it for me too but I'm not sure. This furnace is not an Einstein. It has no smarts at all. It's funny, I have another carrier weathermaker (I don't think they make that one anymore) running the front half of this house just like my old one and this is one smart machine when compared to my simpleton york.
I'll be looking at it tomorrow or some days thereafter. Man is it cold here!!!! And now the snow is coming again.....I'll let you know.
