Although they will charge you a fee it is safer to have a trained technician.

Discharging a capacitor safely. Notice the heat shrinking tube on the aluminum button which is the only conductive path to the outside. They store excess electrical energy during power surges and discharge it during power lulls to provide the appliance with a constant even supply of electricity. Another way to discharge a capacitor would be to source an incandescent light bulb that can tolerate the voltage held in the capacitor.

Hook this up and once the bulb is no longer lit the capacitor is discharged. Use 600v rated wires dont just grab some signal wire that you may have lying around. If you are not comfortable discharging the capacitor you can contact a professional heating and cooling technician.

Most techs use a screwdriver but i show a way to make a capacitor discharge tool to satisfy the most nerdy or safety conscious tech. Thanks for asking about capacitors. The copper mesh around the resistor helps to securely hold it in place in the slot.

Capacitors are found in a number of electrical appliances and pieces of electronic equipment. Once the light is no longer on your capacitor is fully discharged and safe to handle. Again you always want to measure the voltage after its supposedly discharged just to be safe.
