have you ohmed out the wiring, and checked it to make sure there is no mouse chewing or other damage?
It sounds like it is intermittent, but consistent enough that it sets the fault. It may be something as simple as spread contacts in the connector or something. I wonder if you should replace the wire ends to the connector, splice in new ones starting a few inches back?
it should just be a variable resistance in the range selector switch, which if it is new I would assume is OK.
