Jumping in with both feet; but pretty dusty

This is my first post. I was hoping to come up with a higher level of journaling, hence the name Blahgavadgita with the 'blah' describing my blabbing, but not so much eloquent prose today since I spent the afternoon at my other house pressing the reset button in the furnace. I think there is something stuck up above in the exhaust flue because the heat sensor switch is cutting out, but I have to wait to clean it out until my hubby comes home and moves the cabinet that is in my way. I am able to poke at things and press buttons, but I can't swing an old hoosier-type cabinet away from the wall without ruining my back. I got the pipe off the furnace and that is why I am all dusty, but I'm sure that is nothing compared to what I'm going to get into when hubby helps me get way up there. If it gets sufficiently cleaned out but the heat still cuts out, then it means I have to get a new limit switch. You know I've had that furnace 19 years and it's taken me this long to figure out these basic things. I don't hate paying the furnace man so much anymore......he can get done in 15 minutes what would take me hours + running back and forth to my laptop for instructions and/or part numbers. Then usually I still have to get dh involved. Then he spends several hours, a few phone calls, and a couple of laptop visits. Yes, the furnace man channels answers from places that I cannot tap.
