Door conduits must be inspected regularly for cracks and damage. If the door conduit fails, then the wires WILL FAIL, and your furnace will not run. Also, it could be a fire hazard having exposed wires.
Replacing this conduit is simple and does not take very much time.
As always, let us know if you have any questions!
