The last 30 years we've lived in this house, we've had a problem with 1 of the bedroom's electrical receptacles.
On the same wall, there are 2 receptacles about 10 feet apart on opposite sides of the wall. The top plug on each don't work, and the bottom plug do work. The switch in the room has never worked, and we assumed it was because it's connected to those 2 (top) plugs. Since the room adjacent to this one has the exact same setup, but actually do work.
I decide to tackle the problem finally and bought a Receptacle Tester. The reading had no lights turn on. Which indicated Open Hot on the tester. According to the manual this means that the hot contact is not connected.
Does anyone have an much more in-depth explanation about what Open Hot means?
Is this something I could easily fix myself? Is it possible that the switch itself is actually bad?
Offtopic question, There is button on my receptacle tester in the middle, and when i pressed the button while connected to the open hot outlet it gave a faint glow.
What does that button actually do or represent? And what does the faint glow indicate?
