I am changing a four prong to a three prong, but the green and white wires from the cord were both attached to the center connection on the dryer. There is a green screw on the dryer with a white wire going into the dryer, where to, I can't see. Was this dryer previously converted to a four prong? Not sure what to do about the ground. I was told by the previous owner the dryer is 4 or 5 years old.


It sounds like it was previously converted. Age isn't much of an indicator; at 5 years old it should have come with a 4 prong but could have been converted to a 3, then back to a 4.

In any case, the new center wire on the 3 wire cord will go to the center terminal, with a jumper from there to the frame of the dryer - the green screw on the frame would be the best place to put the other end of the jumper. Leave the existing white wire where it is; it will be used to operate the controls and needs to be there.
