Heater problem solved by Mr. Handy himself

After we moved in and Mr. D fired up the heater to make sure it worked... we knew we weren't going to need the heater for a while but he wanted to make sure that when we did it wouldn't need any fixing. Well as he fired it up he heard a thunk like something was lodged in the fan. He turned it off noting that he would need to take a look at that sometime soon. Fast forward 2 months and we need to get the heat turned on. It was down to a cool 67 in the house and we needed to kick it up a few degrees. Remembering that he needed to take apart the heater to see what the problem was he headed up to the attic. I fetched him the tools that he called out to me that he needed from the garage and he was at work. A few moments go by as I hear him upstairs then I hear a chuckle. He calls to me that he has found the problem. As you will see below...

Problem solved.
