Multiple Outlets Not Working? A Master Electrician Explains Why

James is a Master Electrician with over 30 years of experience. We do not use AI for the content of our articles.

There are four reasons why multiple outlets can lose power:

1. The circuit breaker is tripped or off.
2. A GFCI or AFCI outlet is tripped.
3. A loose or open connection in the circuit.
4. A power issue at or upstream from the electrical panel.

I’m going to take you through a step-by-step process to efficiently and quickly identify the problem, and then fix it correctly and safely. These are the exact same steps I take whenever one of my customers has more than one outlet with no power.

Now, before I start poking around in outlet boxes or pulling out my multimeter, I ask the homeowner some very critical questions:

• Exactly which outlets are dead?
  • This tells me whether it affects a large area of the house or is restricted to just part of a room. Also, this often will indicate whether it is a single circuit that is affected or multiple circuits.
  • The location of the dead outlets is key to determining where to look first. For instance, if they are bedroom outlets, I suspect an AFCI breaker first (see section 1 below). Rather, if they are kitchen outlets, I suspect a tripped GFCI outlet (see section 2 below).
  • If it’s a house-wide issue, then the primary focus will be at the panel, meter, or with the utility company (see section 4 below).
• When did they stop working?
  • The answer to this tells me what might have triggered the event. If it was right after a thunderstorm, a nearby lightning strike could cause a voltage spike that can trip a GFCI or AFCI. Or hearing the customer say “It stopped working right after I plugged in my space heater” points to a possible overload on the breaker.
• Is it an intermittent problem?
  • If the outlets work sometimes, and then quit, and then revive again sporadically, that is a strong indicator that there is a loose connection in the circuit (see section 3 below).
• Is it only receptacles, or are lights or fans affected, as well?
  • Knowing which types of loads are affected will also aid me in my assessment of the situation. There could be a loose connection in a switch box. In an older house (where power is run to the lights and switch loops are utilized), the connection problem could be at the light fixture box.

The answers to these quick questions are vital, giving me a starting point from which to attack the real problem with precision and speed.

Depending on the answers to each question above, the order of my next steps may vary a bit. But the most successful, tried-and-true method is laid out for you below.

Approach it in this order:

1. Circuit Breaker Is Tripped Or Off

Once I’ve asked the preliminary questions, I usually will go straight to the electrical panel. This is the quickest and easiest thing to inspect quickly and rule out.

If all breakers are correctly set in the on position, that generally means there is no short-circuit or overload issue.

Locate the breaker that serves the dead outlets and cycle it off and then back on. That will make sure the breaker is reset internally.

With all breakers in seemingly good order, proceed to step 2. Only come back to test the breaker more thoroughly if steps 2 and 3 do not solve the issue. Breakers can fail internally, but it is relatively rare.

If I find a tripped breaker, that gives me an immediate direction in which to begin the investigation. Chances are great that the tripped breaker coincides with the dead outlets.

But don’t take that for granted! Making assumptions is the killer of sound, efficient troubleshooting. Make sure the breaker that is tripped indeed serves the non-working outlets before you go any further.

I will typically ask the homeowner, and they can usually confirm whether it is or isn’t the related breaker. If they’re not certain, I’ll have to verify on my own.

For convenience, put a little piece of tape next to the breaker. This way, you don’t forget which one it was or have to hunt it down each time while testing.

Turn on the tripped breaker by switching it all the way off and then on.

• If it holds, go check the outlets and see if power is restored. If you still have no power at the outlets, move on to the next section. The tripped breaker could be a coincidence, but that’s unlikely. Regardless, we’ll put it on the back burner for now.
• If it’s a standard breaker, and it immediately trips and won’t stay set at all, you have a short-circuit somewhere. Read my article Circuit Breaker Keeps Tripping? for a step-by-step diagnosis walkthrough.
• If the breaker trips and is a GFCI or AFCI, then it still could be a short, but it also may be a ground-neutral connection on the circuit. This will be explained in the next section.

Now that we’ve checked for the obvious signs of a breaker issue, let’s move on to the most likely culprit for multiple outlets not working.

2. Tripped GFCI Or AFCI (Most Common Cause)

Even though both GFCIs and AFCIs monitor and protect against different types of faults, when troubleshooting, they are generally approached using the same methods. So I’ll treat them together, pointing out the minor differences along the way.

Note: GFCIs and AFCIs can take one of two forms – either an outlet or a breaker. GFCI outlets are much more commonly used than breakers, whereas AFCI breakers are far more common than AFCI outlets.

GFCI/AFCI combo breakers (called dual-function) also exist. They provide protection for both types of faults in one device. These are being used more and more as code requirements expand.

Nuisance Tripping

The first thing to take note of is that both GFCIs and AFCIs will sometimes trip, even though nothing is inherently wrong with the circuit. This is called nuisance tripping – because it’s not indicating a safety hazard.

Nuisance tripping occurs when the GFCI or AFCI device senses something outside of its designed parameters that it mistakes for a hazard.

When GFCIs were first being enforced in garages the 1990s, we would get many calls from homeowners complaining that their outlets would trip every time they used their power tools (usually a saw or air compressor).

It turns out, the normal inrush current of the saw or compressor motor would imbalance the circuit just enough so that the GFCI would sense it and assume there was a problem – and therefore trip.

Fortunately, the manufacturers have been able to improve the design and tolerances of the GFCIs and it is no longer a problem in most homes.

The same issue happened with the initial implementation of AFCIs in the early 2000s, only this was more often caused by the internal electronics of appliances.

The AFCIs were oversensitive, and therefore would nuisance trip when certain brands or types of appliances were used on the circuit.

Again, after several years of homeowner and contractor frustration, the manufacturers fixed the tolerances, and nuisance tripping has been greatly reduced.

But it has not been totally eradicated. Especially with AFCIs, every now and then, I will still run across a case of nuisance tripping on a troubleshooting job.

The best way to test for nuisance tripping is trial-and-error.

Try the offending appliance on another AFCI circuit to see if it stills trips. If it trips, the appliance is the culprit. If not, you know the breaker is a suspect for being oversensitive.

If it is a hardwired appliance, you may need to temporarily swap the breakers in the panel to perform this test. Just make sure the breakers you trade are identical in size and type.

But we need to make sure that a real issue doesn’t get misinterpreted as a nuisance trip.

Real Issue Tripping

As mentioned earlier, the location of the dead outlets will help us find the root problem.

Kitchen

If the non-working outlets are in the kitchen, a GFCI outlet is the primary suspect. Sometimes it will be located behind an appliance (even the fridge). Other places it may be is the dining room, breakfast nook, or pantry.

Note: Every modern house will have at least two kitchen circuits, each protected by a GFCI. So you may need to locate two or more in order to find the tripped one.

Garage

If the dead outlets are in the garage, then it is also likely a tripped GFCI outlet. It will usually be located near the electrical panel. Look behind shelving, freezers, stacked boxes, etc.

Bathroom

Likewise, if the affected outlets are in the bathroom(s), then it is likely a tripped GFCI outlet in the bathroom geographically closest to the electrical panel. This is oftentimes the powder bath near the garage, for instance.

Outdoor

If these are outdoor outlets that don’t work, the most likely culprit is a GFCI outlet in the garage, typically near the electrical panel.

Read this article for a detailed guide on outdoor outlet troubleshooting.

Other Living Spaces

If the outlets are in a bedroom, living room, family room, office, or other general living space, then it is more likely to be an AFCI issue. These areas do not generally require GFCI-protection.

Testing a Tripped GFCI or AFCI

Most AFCIs are at the breaker, which we’ve already looked at in the first section.

Once you’ve found the tripped GFCI or AFCI outlet, look for indications that it is indeed tripped.

You will see two buttons: RESET and TEST. The reset button will likely be protruding a bit further out than the test button.

The more obvious indicator will be the LED light. However, it is important to note that each brand has their own method of using LEDs to signify a tripped state or a normal state.

Here is a table showing the most common brands.

Press the reset button firmly until you hear and/or feel a click as the internal mechanism resets.

If it stays reset, then check your outlets for power.

If it won’t reset, and rather the reset button pushes right back out again, then you know you have problem either right there at that outlet or downstream on the circuit.

3. Loose or open connection in the circuit

Since we’ve made sure the breaker is on and there are no tripped GFCI or AFCI outlets feeding the dead outlets, we know there must be an opening in the circuit somewhere. That is likely to be a loose or open connection.

A loose connection can happen anywhere in the circuit where a junction or termination is present. And since most outlets are wired in a series format with each other, anything downstream (further away from the source breaker) of the bad connection will lose power.

The problem can be in any of the following locations:

• A junction box, where wires are joined directly together with a wire connector.
• A device box, where wires are connected to a switch, receptacle outlet, timer, etc.
• A breaker panel, where there are many connections to breakers and bus bars.
• Hardwired equipment, where wires are connected directly to terminal screws.
• A lighting box or fixture, typically using wire nuts for connection.

Most connections usually don’t become loose unless the wiring has been disturbed since the original installation (remodeling, repairs, rodent activity, etc.).

However, if the original installation was not done correctly, over time, and in certain conditions, connections can loosen and become unreliable.

Key distinction: If the outlets lose power and then regain power inexplicably, that is a strong indicator of a loose connection. Intermittent behavior is the number one sign that a connection is compromised, and it must be located and repaired.

A loose connection is almost always associated with arcing. Arcing generates heat and can cause melting and even fires. Do not ignore an intermittent electrical problem.

If you are unable to discover and fix the problem yourself, it is worthwhile to hire a professional.

4. Power issue at or upstream from the panel (Least Likely Cause)

If the outlet problem exists across several circuits, or even the entire house, then the issue is upstream from any individual circuit breaker.

There is evidently some lack of continuity on one or more of the legs of the power feed. This could happen at your main breaker, your exterior service disconnect (if equipped), a meter connection, or with the utility power distribution system.

One thing worth knowing about is a scenario called a lost leg. The utility delivers two 120-volt legs to your home. If power is lost on only one leg, only about half of your house stops working, depending on your circuit layout.

That’s why these situations get overlooked at first. Much of your 120-volt lighting and appliance loads might still work fine, giving the impression of a circuit issue.

But the tell-tale sign is when you notice that none of your 240-volt appliances work. This could be your electric dryer, oven, range, water heater, furnace, AC unit, etc. These require both legs of power to operate.

These are connections you typically cannot test without having the utility company disconnect power to your electrical service. I highly recommend leaving any testing upstream from and including your main breaker to a qualified electrician.

But before calling an electrician, check with your utility. Have them check first. Besides, they may already know of an outage in your area. On that note, you can see if your neighbors are experiencing similar issues.

Conclusion

Troubleshooting multiple dead outlets doesn’t have to be a mystery. With the right questions and a logical sequence, you can usually identify the problem in minutes rather than hours.

In my experience, the vast majority of cases come down to a tripped GFCI somewhere on the circuit — and most homeowners just aren’t sure where to look. Checking behind a fridge or freezer, behind a couch or bookcase, or even behind curtains can oftentimes get you back in action.

Work through the four sections above in order. Don’t skip steps and don’t make assumptions. The breaker that looks fine might not be. The GFCI you reset might not be the right one. The loose connection might be in a smoke detector box in the bedroom rather than an outlet box.

If it gets to be something you’re uncomfortable with, stop and call a licensed electrician. Electricity is unforgiving of mistakes, and there are situations — particularly anything upstream from your main breaker — where DIY troubleshooting has real limits and real consequences.

FAQs

What is the most common reason multiple outlets stop working?

            A tripped GFCI outlet is the most common. Next would be a tripped circuit breaker.

Can one GFCI outlet cause multiple outlets to lose power?

            Absolutely. In fact, that is the usual setup, where one GFCI protects several outlets.

What is an AFCI breaker and how is it different from a GFCI?

            An Arc-Fault Circuit Interrupter (AFCI) is a device that incorporates an extra-sensitive mechanism which will trip when arcing is detected anywhere in the circuit it protects. This arcing can be at any loose connection point, or at a break in the wiring.

There are AFCI breakers and AFCI receptacle outlets, though the breakers are far more common.

Though AFCIs and GFCIs look almost identical, they have very different functions. GFCIs sense ground-faults instead of arcing.

Note: Some devices incorporate both AFCI and GFCI protection in one. These are called dual-function devices.

Why won’t my GFCI reset after I push the button?

            In most cases, the GFCI is still detecting a fault downstream from it. You must clear the fault first.

At other times, the outlet itself might be malfunctioning. GFCIs contain electronics which will eventually fail over time. GFCIs should last at least 20 years, but sometimes external events cause their premature failure.

Don’t replace the GFCI until you’ve ruled out a fault on the circuit. You can do this by disconnecting the LOAD wires and then seeing if it resets. If not, the GFCI is bad.

Check out this article for more depth on GFCI troubleshooting.

What does it mean when half my house has no power?

            If you’re noticing that large of a power loss, the immediate suspect is a lost power leg. This could be anywhere from your main breaker, upstream to the utility transformer at the street.

How do I know if I have a lost leg situation?

            First thing to check is any of your 240-volt appliances. This means your electric oven, dryer, range, cooktop, furnace, AC, etc.

Any gas appliances may still work, so make sure you are checking 240-volt electric appliances for operation. These appliances will have a corresponding 2-pole breaker in the electrical panel (double the size of a standard 1-pole breaker).

Also, check with your neighbors to see if they are having a similar issue.

Can a loose connection cause multiple outlets to fail?

            Yes, because of the series design of most circuits, the wire jumps from one outlet to the next to the next, in a daisy-chain fashion. This means that any interruption in the circuit will cause all downstream outlets to lose power.

When should I call an electrician instead of troubleshooting myself?

            When dealing with electricity, any time you feel unsure about what you’re doing, you should seek advice or assistance from someone with experience. Contacting a licensed electrician is the most certain way to a safe and effective repair.

However, if you have a knowledgeable friend or family member, they may be able to help as well.

Being “invisible”, electrical is not as intuitive as plumbing or other trades, and many inexperienced folks take it for granted. This can lead to inadequate or dangerous “repairs” and potentially cause continued failure or even fire damage or personal injury.

Rule of thumb: If you’re not confident in your own abilities, get help from someone who will fix it right the first time.
