I’m trying to change the cord on a second-hand dryer that came with a 3 prong cord to a 4 prong to match the outlet I have.
I have a decent sense of what I need to do to match up the hot-neutral-hot wires but my issue is what to do with the ground wire.
For whatever reason the current 3 prong configuration had the green ground screw already in place but with the head on the interior of the dryer (see image). So I cannot simply unscrew and then screw on to attach the ground wire as-is.
Is it imperative that the ground wire on the 4 prong cord be fastened through that screw or is there some easy way around this? I also am unsure if I can even remove the entire back panel because there are a few other inverted screws with heads on the interior of the machine.
EDIT: I also now noticed that internally the current backwards ground screw is connected to a green wire, shown poking out in the pic
Here’s my current configuration! I wasn’t able to find an up-to-code green ground screw that could thread itself but I got a similar sized sheet metal screw that seems to work.
Follow up questions:
Is there any safety issue with not technically using a green ground screw?
Is the ground wire making enough contact, as much as can be seen from the picture? I was told that essentially as long as it’s touching the chassis that’s enough. The angle is super awkward with the plate that holds the wires in.
