Just got into a rental house and one outlet didn't work, so I used my handy dandy circuit tester and none of the lights came on (supposedly that means "open hot." )
(The circuit tester does work, it shows normal on other outlets.)
Now what? I am a renter, so all I really care about is safety, fire, etc...I do not want to spend $ just to make this outlet work, if it is nonfunctional but not a fire hazard, I'm happy to leave it alone. If it is a potential hazard I can bug the owners to have it looked at by an electrician. (I want to know whether it is worth doing that, not interested in the vague thought of "just to be safe, have it looked at" -- before calling someone in, I want to know, what are the possible reasons for this test outcome? )
I did turn off the main power and took it apart, looks like it's hooked up right to me, black and white wires going to the right places, and a copper (ground) going to the side screw.
