Hello all, I would appreciate some help diagnosing a circuit problem
I lost power to several rooms after turning on the kitchen light the
other day. When I checked the circuit breaker panel, no breakers were
in the tripped position. The bathroom and kitchen lights do not work,
however the wall sockets do. Sockets in the bedrooms and living room
are not working either. All appliances and heating is working.
I tried resetting the breakers nothing has seemed to help. Any advice?
The circuit is daisy-chained from one fixture to the next. the loose
connection is at either the last device on the chain that works (A) or the
first one that doesn't work (B).
W, X, & A are working, B, Y, & Z do not.
It's easiest to check "B." If the problem cannot be found at "B," then the
trick is to find "A" This can be done by flipping off the circuit breaker to
discover all the other outlets/lights on the same circuit. One of them is
I can think of a couple more things to check, but that requires opening up
the electrical panel box. It sounds like you're not comfortable with that,
or else you'd have done it already.
On the off chance you (or a friend) are OK with opening the panel box, make
sure the breakers are all delivering power. And then check to see if the
neutrals and grounds are tight.
You need a voltmeter to verify that power is getting through all the
You need a map of where your circuit breakers go (too late to say that
should have been done long ago). Trip them one at a time and write
down what lights go on and off. The one you are having problems with
may not do anything. Or it will at least be in the vicinity of those
that do not work.
BTDT. Open up the switch boxes on that circuit, starting with the one
you flipped when it crapped out. Bet you have a bad switch, or a loose
or shorted connection, or maybe a nick in the wire jacket arcing to the
grounded metal box. If switch isn't dogged down tight in box, it may
have drifted close enough to one side for an overstripped wire to short
to the box. May as well have a new switch in hand when you open it up,
in case you don't see any obvious problems- they are only a couple of
bucks.(Oh, yeah, turn the breaker to the OFF position, first.)
