Outlets that Lost Power

Electrical Question: What happened tom make my outlets stop working?

The following electrical questions have similar problems where power was lost to outlets. The typical cause for lost power to outlets and and methods of repair are described below.

Why did the outlet stop working?

I usually try to fix stuff before I call a pro, but this electrical outlet has got me stumped.

  • Someone plugged a hairdryer and a space heater into a standard duplex bathroom outlet at the same time, and the outlet stopped working.
  • The breaker didn’t trip.
  • Both the standard outlet and another GFI outlet next to it are not working.
  • These broken outlets share a breaker with 3 lights and a vent, which are still functional.
  • The bathroom also has a functioning GFI outlet, so we’re making due.
  • The broken GFI has 3 sets of wires going to it.
  • One wire pair reads 1.2 volts 60 Hz when the breaker is closed, but 2.4 volts 60 Hz when the breaker is open.
  • The other GFI wire pairs and the wire pair in the standard outlet have a minimal voltage on them.
  • I can’t see much of the wiring, some of it is visible in the attic, but much is concealed in the walls.

Any ideas what happened?
Thanks

This electrical wiring question came from: Elliot, a Homeowner from Winter Springs, Florida.

What could the problem be with out Outlets?

  • All outlets in room not working but 1/2 of one, breaker not blown in box.
  • My wife turned on lights in morning and turned right back off, left room and returned a few minutes later and turned back on only one lamp was on and it popped and went out.
  • Outlets are fixed where top is controlled by wall switch and bottom is hot all the time.
  • We have checked all outlets and no wires are loose or look burned. What are your suggestions?

How to Troubleshoot Electric Outlet Problems

Problems that May Prevent Electrical Outlets to Stop Working and Where to Look.

  • The most common reason why residential home outlets stop working is due to a break down that occurs within the electrical circuit of the outlet.
  • Most typically it is found that a wire connection that is made in or onto one of the outlets that is a part of the circuit has deteriorated to the point of burning apart from the connection.
  • Some of the connections that are burnt apart were incorrect wiring additions to the existing circuit, or the push-in connections to the back of a receptacle outlet overheat and finally let go.
  • Outlet circuits may be affected when high consuming devices are used such as space heaters and vacuum cleaners which demand high amounts of power which is passed through many of the devices between the outlet and the electric panel.
  • It may also be discovered that the GFI outlet has been affected and may require replacement.
  • In some cases an electrician will discover problems with the outlet circuit in the electrical panel where either the neutral wire or the power wire to the circuit breaker has burnt wire due to a loose or overloaded condition of the circuit.

Repairing Burnt Electrical Wire on an Outlet Circuit

  • Before working with electrical wiring for any reason the circuit must be identified, turned off and tagged with a note indicating that work is being performed.
  • Burnt electrical wire must be trimmed away so a fresh connection may be made with clean wire.
  • If the affected wires become too short then additional wire of the same size and type of insulation may be spliced using UL approved wire connectors.
  • If an outlet device or switch was affected  and has burnt terminal connections then it should be replaced with a new device with the same electrical specifications.

  1. Dave Rongey says:

    Hi Patty,
    The circuit should be turned off and repaired as soon as possible. The electrical wiring inside the outlet boxes and lighting devices that are on the same circuit will need to be inspected for a loose or burnt electrical wire connection, or faulty wire splice. Once identified the appropriate repairs will be required to restore the power to the room. This is best performed by a licensed electrical contractor.
    I hope this helps,
    Dave

    I plugged a vacuum cleaner into an outlet and it worked fine but then it quit. Now the lights in that room do not work but in the other side of the room the outlets work fine. I checked the breakers and changed the outlet.
