Plug Wires Red
my dryer has 3 wires(yellow, white, blue) but my plug has 4 wires(red,white,green,black)which go where?
i need to know what wire goes where
A little background here. Your dryer is a 220 volt appliance and until recently they had only 3 wires to it, to match the receptacle. Now they seperated the neutral (white) and the ground (green or bare copper) but the two still attach to the same busbar at your electrical power panel. So heres the color schematic you need. Your dryer hot wires are yellow and blue and attach to the red and black wires which are 110 volt hot wires from the panel (together they add up to 220) , the white wires go together as these are your neutral wires which return power to the panel thus completing your circuit, the green or bare copper wire can be attached to the white wires or attached to the metal electrical box if you have one as the equipment box. Your receptacle box may be plastic which then you have no choice but to attach it to the white wires. If you have a electrical meter, it would show 110 volts across either the red/yellow or blue/black wires to either the white or green wires, with 220 volts measuring across the red/yellow and blue/black connections. There is no appliance that runs on 220 volts but rather 2 110 volt circuits,which in a dryer one 110 v circuit runs the timer and lights while the other runs the heating element itself. Be sure to turn off the breaker before attempting and make sure your connections are good and tight or youll have problems. Good luck
