When something electrical fails, the question is usually framed as repair or replace. For most household devices the answer is simple: an outlet, a switch or a breaker is replaced, not taken apart. But replacing the part is often not the whole repair. The connection behind it, the wire feeding it, or the circuit it sits on may be the actual problem. Here is how we think about it, part by part.
Outlets
Outlets wear out. The contacts that grip a plug lose tension over years of use, and a plug that falls out or feels loose is a sign the outlet should be replaced. Replace it as well if it is cracked, discolored, warm, or has scorch marks.
What gets repaired is the connection. Many outlets are wired with push-in connections on the back, which can loosen and overheat over time. When we replace an outlet, we connect it with the screw terminals, check the condition of the wire ends, and cut back any wire that is darkened or brittle. If one outlet in a chain fails, we check the others on the same circuit, because a failed connection upstream can kill every outlet after it.
GFCI outlets have a lifespan too. One that will not reset, trips with nothing plugged in, or fails its own test button should be replaced. In kitchens, bathrooms, garages and outdoors, the replacement needs to be a GFCI again. Outdoors, it should be a weather-resistant model under a cover that stays closed with a plug in. See outlet and GFCI repair for more.
Switches and dimmers
A switch that feels mushy, crackles, gets warm, or works only some of the time should be replaced. Dimmers are the most common call here, and the cause is often a mismatch rather than a failure: older dimmers designed for incandescent bulbs do not get along with many LED bulbs. The result is flicker, buzzing, or lights that will not dim smoothly or switch fully off. The repair is a dimmer rated for LED loads, or LED bulbs labeled as dimmable, or both. Our lighting repair page covers dimmer problems in more detail.
Breakers
A breaker is replaced, never repaired. The questions are whether it actually needs replacing, and whether the problem is the breaker or something it is protecting. Replace a breaker when it:
- Will not latch or stay on, even with nothing on the circuit.
- Is warm, discolored, or has a melted or burned look at the terminal.
- Trips well below the load it is rated for, after the circuit has been checked.
- Is physically damaged, or is the wrong type for the panel.
A breaker that trips because the circuit is overloaded or has a fault is doing its job, and replacing it fixes nothing. That is why we test the circuit before replacing a breaker, and why we never install a larger breaker to stop nuisance tripping. The breaker size is set by the wire, not by how much you want to run. Our guide to why a breaker trips again on reset explains the difference, and circuit breaker repair covers what we do about it.
Replacement breakers must be listed for the panel they go into. Older panels sometimes take breakers that are hard to find, or no longer made, which can tip the decision from repairing the panel toward replacing it.
Light fixtures
Fixtures are the one category where repair often makes sense. A failed socket, a worn switch in a fan, a dead LED driver, or a loose connection in the canopy can usually be fixed, especially on a fixture you like. Replacement makes more sense when the fixture housing is corroded, which is common outdoors near the water, when parts are no longer available, or when the cost of the parts approaches the cost of a new fixture.
Panels
A panel is repaired when the damage is limited: one burned bus stab, a few failed breakers, a corroded connection that can be cleaned or replaced. It is replaced when the damage is widespread, when breakers for it are no longer made, when it is one of the older designs with a known record of problems, or when it is too small for the house as it is used today. Our signs a panel needs replacing post lists the warning signs, and electrical panel repair explains how we assess one.
When the real problem is the circuit
Sometimes the part keeps failing because of what is around it. Three patterns tell us to look past the device:
- The same device fails again. An outlet or breaker replaced last year and failing again usually points to a loose connection elsewhere, an overloaded circuit, or heat.
- Several devices on one circuit fail. That points to the wiring or to a connection that feeds them all.
- The circuit is doing too much. A kitchen, bathroom or home office circuit running more than it was sized for will keep tripping and heating devices. The fix is a dedicated circuit for the heavy load, not a stronger part.
In older homes, the wiring itself can be the issue: brittle insulation, aluminum branch wiring that needs devices and connectors rated for it, or connections that have been modified over the years. We will tell you what we see, and when a repair is enough.
