Before servicing, unplug the power cord to prevent an electric shock.

When replacing parts ,use only manufacturer's recommended components for safety.

Unplug the powercord and short the two prongs of the plug with ajumper wire .

Turn on the power switch .

Measure the resistance value with ohmmeter between the jumper AC plug and each exposed metal
