10D471K VARISTOR PDF

For example if there is a power surge, the varistor, normally having a very high resistance, responds to the voltage spike by absorbing its energy with a very low resistance. Disconnect the electronic equipment from the wall outlet. Open the case with the screwdrivers and locate the varistor. It is usually a brightly colored disk the size of a coin.

For example if there is a power surge, the varistor, normally having a very high resistance, responds to the voltage spike by absorbing its energy with a very low resistance.

Disconnect the electronic equipment from the wall outlet. Open the case with the screwdrivers and locate the varistor. It is usually a brightly colored disk the size of a coin.

The varistor will likely be wired to a fuse holder. If the varistor is visibly burned through or broken, replace it immediately. Heat the lead with the soldering iron until the solder melts, and remove the solder with the desoldering tool.

Carefully pry the lead loose from the connection with the long-nosed pliers. With the varistor removed from the circuit, you can now measure its resistance. Turn the multimeter on and set it to read resistance times ohms.

Touch one meter probe to the free varistor lead and the other probe to the connected lead. Read the resistance on the meter. If it reads nearly infinite resistance, the varistor is still good.

If it reads very low resistance, the varistor is blown. If the varistor is blown, disconnect the remaining lead and solder a new varistor of the same rating in its place.
