  • CommonA tripped breaker for the garage circuitGarages often have their own dedicated circuit that can trip from tools or extension cord use.
  • PossibleMoisture or dust intrusion in the outletGarages are exposed to more dust, moisture, and temperature swings than indoor rooms.
  • PossibleAn overloaded circuit from power toolsTable saws, compressors, and similar tools can trip a garage circuit under load.

What to do

  1. Look for a GFCI outlet in the garage and press reset, even if it's not the dead outlet itself.
  2. Check the breaker panel for a tripped garage circuit.
  3. Unplug tools or a freezer/fridge if several devices share that circuit.
  4. Inspect the outlet for dust, cobwebs, or signs of moisture, especially if it's near a garage door.
  5. Test the outlet with a lamp or simple device to confirm it's dead.
  6. If it's a freezer or fridge on that outlet, check on the contents promptly if power has been out a while.
  7. Call an electrician if resetting GFCI and breaker doesn't restore power.

Tools and parts

  • Non-contact voltage tester

When to call a pro

Call an electrician if the garage outlet stays dead after checking GFCI and breaker, especially if a freezer or fridge relies on it.
