No Power in One Room? Why Half Your House Went Dark
Half the house works, one room is dead, and no breaker looks tripped. Here's what's actually going on — from a sneaky tripped GFCI to a lost leg of your service — and how to narrow it down safely.
This call always comes in the same way: one bedroom, the kitchen, or half the basement has no power — and the homeowner has already looked at the panel and every breaker 'looks fine.' Here's how to narrow it down before you spend a dollar.
Check these in order
- 1. GFCI outlets — one tripped GFCI in a bathroom, garage, or basement can kill outlets in rooms nowhere near it. Press every TEST/RESET button in the house, including the one hiding behind the storage shelves.
- 2. Breakers that tripped without moving — a breaker can trip internally and still look ON. Push each one firmly to OFF, then back to ON.
- 3. AFCI breakers — these have a test button on the breaker itself and trip for arc faults. Same reset procedure.
- 4. A tripped main or half-main — if every other room is dead in a pattern, one leg of your 240V service may be down. Some lights work, some don't, and 240V appliances act weird.
What it usually turns out to be
In Baltimore-area homes, the dead-room culprits we find most: a back-stabbed receptacle that finally failed mid-run (everything downstream of it goes dead), a tripped GFCI nobody knew existed, a failed breaker in an older panel, and — in rowhomes with older services — a corroded neutral or a lost leg at the meter.
If half the house is dead in a checkerboard pattern, or lights are unusually bright in some rooms and dim in others, suspect a lost neutral or lost service leg. Bright-and-dim is the dangerous one — it can fry electronics. Kill the main and call.
What it costs
- Find and repair the failed connection or receptacle: $150 service call covers most of these
- Failed breaker replacement: $150–$350
- Service or meter-can problems: we diagnose, then coordinate anything on BGE's side with you — you never call BGE alone
