How do you fix a bad capacitor?

Use an insulated screwdriver to short-circuit the terminals of the bad capacitor. This discharges any stored electrical energy and reduces the risk of electric shock. Remove Access Panel or Casing: If necessary, remove the access panel or casing covering the capacitor.

Can you put capacitors in parallel?

The biggest risk to putting them in parallel is that the bad cap may leak and corrode the circuit, but because most of the current will go through the new cap the old cap should deteriorate slowly. In the first picture the new capacitors are laying on their side, hot melt glued to the front of the board.
