Why does only part of my house have power?

Selective power loss is almost always an in-home issue: a tripped breaker or GFCI cutting one circuit, a failed outlet, or the loss of one of the two 120-volt legs feeding your panel. A utility outage would cut everything, so partial power means the problem is inside your home's electrical system.

What is a tripped GFCI and how do I reset it?

A GFCI is a safety outlet (common in kitchens, bathrooms, garages, and outdoors) that cuts power when it senses a ground fault. Multiple outlets are often wired downstream of one GFCI, so a single trip can deaden several outlets. Find the outlet with 'test' and 'reset' buttons and press 'reset.' If it won't reset or trips again, there may be a fault to investigate.

Half my house has power and half doesn't — is that serious?

It can be. A clean 'half the house' split often means one of the two 120-volt legs feeding your panel has been lost — at the main breaker, the main lugs, or the utility service drop. This needs a licensed electrician (or the utility, if it is the service side). Do not ignore it, as it can also indicate a loose neutral.

Can a partial outage damage my appliances?

Yes. A lost or loose neutral can cause some circuits to receive too much voltage and others too little, which can damage electronics and motors. If you notice lights brightening and dimming, or appliances behaving strangely during a partial outage, unplug sensitive electronics and call an electrician promptly.

I reset the breaker but power didn't come back — what now?

If a reset does not restore power, the breaker may be faulty, the circuit may have a break, or the issue may be upstream (a lost leg or loose connection). Stop resetting and have a licensed electrician diagnose it, especially if the breaker trips again immediately.

Partial Power Outage in House — Causes and What to Do

A partial power outage — where some rooms, outlets, or appliances work while others are dead — is one of the most common in-home electrical problems, and it is almost always a wiring or panel issue rather than a utility outage. A true public outage cuts everything. When power is selective, it usually means a single tripped circuit, a tripped GFCI, or, more seriously, the loss of one of the two 120-volt 'legs' that feed your home. This guide explains the likely causes and the safe steps to take.

Quick check: is the problem inside your home?

Answer a few questions to narrow it down. The more of these that apply, the more likely the issue is on your side of the meter.

Do your neighbors still have power?
Is only part of your home affected?
Does a breaker keep tripping repeatedly?
Are your lights flickering or dimming?
Did it start right after using an appliance?
Any burning smell, sparks, or smoke?

Safety check first

Stop and call 911 and your utility if you have a burning smell, smoke, sparks, buzzing, very warm outlets or the panel, or any water near electrical equipment. A partial outage combined with any of these can signal a dangerous fault. Do not keep resetting breakers under these conditions.

Most common causes (least to most serious)

- A tripped branch breaker: one circuit feeds the dead rooms. Resetting it usually restores power.

- A tripped GFCI outlet: kitchen, bath, garage, and outdoor outlets are often chained to one GFCI. If that GFCI trips, every outlet downstream of it goes dead. Press its 'reset' button.

- A failed outlet or loose connection: a backstabbed or worn outlet can lose power and cut everything wired after it.

- A lost 120-volt leg: your home is fed by two hot legs. If one is lost — at the main lugs, a main breaker half, or the utility service — roughly half the house goes dark while the other half works. This is more serious and needs a professional.

- A loose or failing neutral: can cause flickering, partial power, and damaging voltage swings. This is a safety issue requiring prompt attention.

What you can safely try

- Find and reset any tripped breakers (a tripped one sits between off and on; push it fully off, then on).

- Locate GFCI outlets in kitchens, bathrooms, garage, and outside, and press 'reset.'

- Note the pattern: is it one room, or clearly 'half the house'? Half-the-house points to a lost leg and a call to an electrician or utility.

- Unplug high-draw appliances on the affected circuit before resetting, in case an overload caused the trip.

When to call a professional

If resetting breakers and GFCIs does not restore power, if a breaker trips again immediately, if roughly half the house is dead, or if you see flickering and dimming across the home, have a licensed electrician diagnose it. A lost neutral or a failing main connection can damage electronics and create a fire risk, so it should not be left unresolved.
