Guide for Testing GFCI Outlets and Wiring
Electrical Question: My daughter plugged in my vacuum cleaner in the bathroom and popped the GFCI plug which both my bathrooms are back to back and now I have no power.
- I checked the breaker and tried resetting the GFCI but it won’t go on and the green light is not on.
- I replaced the GFCI outlet and put a GFCI tester in it and its marking red and yellow which is telling me hot and ground contacts interchanged so I don’t know what do next.
