I have 4 outlets in one of my bedrooms. One of the outlets is working with no problem at all both the top and bottom plug work. The other three outlets in the bedroom, the top outlet works but there is no power going to the bottom outlet. This has occurred on all 3 separate outlets. What could be the cause of this, should I be concerned. I tried resetting the breaker just in case, but that did not work. Thanks in advance
In addition to Daniel's comment above about any wall switches in the room with unknown function, I suggest adding one of these 6-dollar outlet tester tools to your DIY bag. Just plug it in and it will diagnose/report many common issues with wall outlet wiring (just in case.)
Note, if you plug one of these into an outlet that is 'switched' by a wall switch somewhere, then the lights will show the 'open hot' condition which is all three lights out. (I know, it's not intuitave: "no-lights means what?")
So you plug it in and leave it in one of the bottom outlets, then go around flipping only one switch at a time until it shows "off-on-on" which signals "correct."
Remember (while it is unlikely) it could be that the lower plugs are wired in 3-way so, continue flipping switches one at a time, just to make sure the plug doesn't go on then off again.
