No heat- 2000 Goodman 100k Furnace with blown fuse. Inspection of system found broken limit switch. Further inspection found cracks in heat exchanger. Blower motor has vibration and is leaking oil. Inducer motor has high amps, flame sensor needs replaced and ignitor shows signs of wear and is recommended to replace. Flue pipe has asbestos tape on the joints.
