Caution, capacitors store and hold energy. Use an insulated screwdriver to bridge between the two sets of posts to bleed off this stored energy. Hold onto the insulated part of the screw driver when you do this. It only takes a second to bleed off the energy, the capacitor is then safe to remove from the unit.
