A capacitor can be exceptionally hazardous. It can hold a lethal fee consistently even when not connected to a source of power. Never ever touch the terminals of a capacitor up until you have actually discharged it.
As a result of its capacity to save power, it threatens also when disconnected from a source of power. In order to manage it safely, it has to first be released.
While it can be released by simply shorting the terminals with each other, this is dangerous to you and can create electrical arc damage to tools and to the capacitor.
To securely release a capacitor made use of on a refrigerator's motor, you will certainly require a 20,000 ohm cord injury resistor rated for 2 watts or even more, 2 screwdrivers and two jumper cords with alligator clips on each end of each cord. Very first clamp one clip to one cord of the resistor. Hook up a clip from the other cord to the other cord on the resistor. Take the clip on the other end of either wire and attach it to a screwdriver. Take the staying totally free clip and clip it to one more screwdriver. While holding the shielded manages of the screwdrivers, touch one screwdriver to each terminal on the capacitor. After a few secs the capacitor should be released. Do not hold the capacitor throughout this procedure because it can become hot as it dissipates the capacitor's power.
After adhering to the actions over, for an included margin of safety and security, hold a screwdriver by the insulated manage. Touch the cutter of the screwdriver concurrently to both terminals of the capacitor making certain it has actually been released.
