humming electrical wiring
I have a humming in my bedroom wall. It humms day & night. I have turned the breaker for that room on & off. When I turned the breaker off--the humming stopped. When I turn the breaker on--the humming starts again. It has been making the noise for 5 days, since I noticed it.
I had not noticed it before--because I usually run a fan 24/7. Five days ago, I turned the fan off, cause it got cool at night & that's when I noticed the humming noise.
Can anyone help?
