Electrical Test: Voltage

• When testing for the presence of proper voltage, you're looking for either 120 volts AC or 240 volts AC, depending on the type of appliance.
• When testing for voltages at electric dryer heating elements and electric range or stove elements, you're looking for 240 volts AC.
• When testing for control voltages to solenoids, timers, etc., on washers and other 120 volts AC appliances (i.e., they do not require a 240 volt AC plug) then you're looking for 120 volts AC.
• Anything less means you have a problem somewhere in the circuit, usually an open switch or thermostat or one with poor continuity. Sometimes it could be a bad wire connection--look for burnt or discolored wires.
