It is very common for wall plugs in bathrooms, on exterior walls, and garages to all be on the same GFI protected circuit. In most cases, all these plugs are protected by the GFI plug in the garage.
When you press the "test" button of a GFI outlet, it's supposed to make a clicking sound, and the "reset" button is supposed to pop out. If you pressed the test button and you didn't hear anything, it could be a couple of things:
- Your GFI has already been tripped. You just have to press the reset button in all the way, and test it again to see if it trips.
- This GFI has no power going to it at all. Check your circuit breaker panel for tripped breakers. If you can't identify any tripped breakers, try lightly pressing the breaker switch towards the center of the panel. If it has little or no resistance, it might be tripped. To re-set it, turn the breaker off, then back on again. If it is tripped, and after you reset it, it flashes, or goes right back to the tripped position, you have a larger problem somewhere and need to call an electrician.
- Your GFI is faulty. If you know you have power on that plug, and you press the 'test' button, and the power doesn't go off on that plug, you should replace the GFI, or have a licensed electrician replace it.
If you go through all these steps, and it doesn't provide a solution to your dead plugs, then it might indicate a larger issue (like a cracked or broken outlet on the circuit). You should call an electrician if you're not comfortable with electricity.
