Humming noise coming from panel
My bro-in-law called me and he said they have a humming/sizzling noise coming from their panel. It's a 100A service with a new panel recently installed. I know there is 1 ground rod installed. He believes it's normal.
Everything seems to be working ok. I haven't went and looked at it, but I thought I would tap into a huge pool of knowledge here first. Thoughts?

Definitely no bell. The dogs are his door bell. 
The house was his grandmothers and has been "rewired."

Thats not normal for a Resi panel, I bet you'll find a hot spot pretty quick.

Had one on sat. that was humming found the main to be hot to the touch changed the main checked the grounds/neutrals pulled the meter checked the neutral, even went as far as checking the taps on top of the services head everything is fine now. I seem to find myself always going the extra.

No GFCI or AFCI breakers. I'd bet there isn't a GFCI recep anywhere in the house. I'm going over this weekend to check it out.
Thanks guys.

Did this just recently start humming?
Waiting till the weekend may be too long, especially in an older home.
Hope the smoke detectors are functioning.

No, It's been going on for quite a while from what I understand.

Give the board a thermal heat check first. Then look to mechanical/electro problems if this proves safe ,

Maybe it hums because it doesn't know the words.

This reminds me of my all time favorite service call.
A lady tells me there is a humming sound somewhere and asks me to figure it out. We walk into her bedroom and I quickly trace the noise to a vibrator under the blanket on her bed.
I picked it up, turned it off, looked her in the eyes and said "Here's your problem right here Maam".
I figured she rubbed one out and fell asleep while it was still running.
