Up until a month or so ago, all of my house's electrical receptacles worked
fine. Now, one electrical receptacle in each of my house's two bedrooms does not
work. All other receptacles in the house work and have readings of about 120
The two receptacles that do not work have "in common" a red wire.
The red wire to white wire (or neutral) voltage readings are all about 44 volts.
The black wire to red wire voltage readings are about 66 volts.
The two bedrooms and living room all have ceiling fans and ceiling light
fixtures. These three rooms also have a 3-switch control near their entrance.
One switch controls power to the receptacles. Another controls the fan. And the
third controls the overhead light.
My area has seen more rain than usual. On the other hand, humidity is very low
here; any moisture dries quickly.
Why would the red wire suddenly fall to 44 volts (instead of the usual 120
volts) in the two rooms?
All suggestions welcome. I will be troubleshooting further today.
