What this problem usually means

Partial power troubleshooting

If only part of the house has power, some lights become unusually bright while others dim, or appliances behave unpredictably, the problem may involve a loose or lost neutral, damaged service connection, failed breaker or utility issue. Abnormal voltage can damage connected equipment and should be diagnosed promptly.

Why this page matters

The symptom is not always the source.

Voltage testing helps separate an internal wiring problem from a meter, service or utility-side condition before equipment is replaced.

A focused diagnosis helps avoid random part replacement, repeat visits and leaving the real failure hidden elsewhere in the circuit or service equipment.

When to call quickly

Do not wait on these warning signs.

  • Some lights become very bright while others dim
  • Appliances behave abnormally
  • There is heat or a burning odor at service equipment
  • The utility has checked and says the issue is customer-side

Questions customers ask

Direct answers before you call.

Why does only part of my house have power?

Possible causes include a lost utility leg, loose or lost neutral, failed main or feeder breaker, damaged service equipment or a connection failure inside the property.

Can partial power damage appliances?

Yes. Abnormal voltage—especially from a neutral problem—can expose 120-volt equipment to unsafe conditions. Turn off sensitive equipment when safe and arrange prompt testing.

Proof—not vague promises

A lost neutral can damage connected equipment.

Voltage testing helps separate an internal wiring problem from a meter, service or utility-side condition before equipment is replaced.
