As I was turning off the stove, I heard a loud beeping and received the code: bad line. The stove top continues to function normally after disconnecting the main cables from the control unit. Is the stove control board is malfunctioning?
You should inspect your home wiring and unit to ensure that no wires are broken or damaged. The ohm value on your oven sensor should be 1085 ohms. After checking everything and all looks good. But you still have the same problem, then the control board is most likely faulty. We can repair faulty control boards.
