I have a power humidifier attached to my furnace which isn't working. I believe there is some part missing in it. I could not locate the model #. The only thing it says is MUELLER CLIMATROL, DIVISION OF WORTHINGTON CORPORATION. Can someone tell me where I can go and get it checked or if I can get a diagram of parts. I have already been to couple of places and those guys have no clue.I am stationed in Michigan. PLEEEASE HELP.
