Fix it yourself
Electrician repairs you can do yourself
Resetting breakers, replacing batteries and testing outlets are safe. Anything behind a faceplate or inside the panel is where licensed work begins in most markets — the guides say exactly where.

Burning smell from outlet
Unplug whatever is in the outlet if the plug is cool enough to touch; otherwise leave it.

Dead outlet
Test the outlet with a lamp that works elsewhere; test the other outlets in the room to see how far the outage extends.
easy 10–30 min· $0–10 for a tester
- 03Open
Electrical Buzzing Sound
Find the source: stand still and listen at each outlet, switch, dimmer and the panel; a dimmer with LED bulbs that hums quietly is common and harmless if nothing is warm.
easy 10–30 min· $0 — isolate and call
- 04Open
EV charger not working or charging slowly
Read the status light or app: a fault code tells you whether the charger sees a ground fault, an over-temperature, or a car-side refusal; write it down.
easy 15–45 min· $0 — checks and resets only
- 05Open
GFCI outlet keeps tripping
Unplug everything on the GFCI and on the outlets downstream of it, press RESET, and see whether it holds.
easy 15–40 min· $0 — a replacement GFCI is $15–25 if you are comfortable with outlet replacement where allowed
- 06Open
Lights dim when appliances turn on
Write down which lights dim and which appliance starts them: a dip on the vacuum's own circuit is a full circuit; a dip through the whole house when the AC or dryer starts is the service or the panel.
easy 20–60 min· $0–20 for a tester and bulbs
- 07Open
Outdoor motion sensor light stays on
Reset it: switch the fixture off at the wall switch for 30 seconds and on again — a brief off-on flick puts many sensor lights into manual-on mode until they are reset.
easy 15–45 min· $0 for adjustment; $15–40 for a sensor head
- 08Open
Solar panels producing less power than expected
Compare like with like in the monitoring app: this month against the same month last year, and a clear-sky day against a clear-sky day; cloud and season explain most 'declines'.
easy 30–90 min· $0–30 for a pole brush
- 09Open
Tripping circuit breaker
Unplug or switch off everything on the circuit that tripped, then reset the breaker: push it fully to OFF, then to ON.
easy 15–45 min· $0
