I had the box off last year and I cleaned all of the debris out of the box and put new seals on. Based on all of the stuff that came out of the box, I thought for sure that was the reason the heat didn't work. I even blew between the fins with compressed air. Maybe I didn't get it all.

Andy, I thought the intake went to the bottom to fill the core up and push air out of the top?
