How to Fix a Bathroom Light and Outlet Problem
Electrical Question: I went to my bathroom and turned on the lights that are above the mirror (no exhaust fan) The lights went out and now none of the lights or electrical outlets in the master bath or master bedroom, which is attached to master bath, are working.
- Checked the Circuit Breakers
I looked at the breakers to see if any of them were tripped and they weren’t. I turned them all of anyway and turned them back on.
- Restored the Power
Everything came back on in the bedroom and bathroom but when I turned the lights back on in the bathroom it did the same thing.
- Lost Power
Now nothing will come on.
This electrical wiring question came from: Heather , a Homeowner from Knox, Indiana.

How to Troubleshoot and Repair a Bathroom Light Circuit Problem
- Bathroom Light Power Source
It is possible that the vanity light power source comes from a GFCI outlet that is located in one of the bathrooms.
- Inspect the Light Switch and Fixture
Make sure the light switch and fixture do not have am accumulation of steam or moisture which can cause the GFCI outlet to trip off.
- Check the Light Bulbs and the Fixture
Replace any light bulbs that may be faulty. Up to this point, if everything looks OK then the wiring of the light fixture and the circuit splice connections will need to be checked for a bad or deteriorated connection and then repairs must be performed as needed..
- Reset the GFI Outlet
After the checks and repairs have been made turn off the light switch and reset the GFI Outlet by pressing in the RESET Button.
- Further Electrical Wiring Inspections
If the preceding checks did not reveal any problems then the circuit that supplies power to the bathroom lights will need to be identified and tested for the cause of the fault. All the affected lights that are controlled by the light switch should be opened so the electrical wring may be inspected for burnt wiring and faulty connections.
- Replace the GFCI Outlet
If the problem seems to be associated with the GFCI Outlet then the GFCI outlet may be faulty and need to be replaced.
