Well if it's faulty, it's faulty. It's the same like if your kettle does not boil water, you cannot turn it up to burn off limescale.
Only thing you can do is measure resistance, it should be very low like 1ohm or less, basically almost short circuit, if it's open circuit it's faulty and need to be replaced.
