ceiling fan hum
#1

I have two Hampton Bay ceiling fans from the Home Depot that I installed separately in the same location. A noticeably loud "electrical hum" emanated from the first, and didn't resolve for a couple of months. I took it down & tried the second one. Same thing. Not quite as loud, but still there.
No dimmer switch. Separate switches for fan & light control.
I'm wondering if this is an outlet problem, or just two junk fans.
Part 2: Home Depot guy told me I should try sacrificing an old extension cord & connect it to the hot & neutral wires in the fan. Not sure which wire in an extension cord is hot & which is neutral, though. Polarized plug is neutral, I assume? Don't worry, I won't try anything without hearing back from somebody.
Thanks.

The neutral is the wire that is connected to the wider of the two blades on the plug. But I think the HD guy is trying to get you killed so you'll quit coming back and bothering him.

I never like those humming or buzzing sounds either,
I bought a hunter fan, and learned a few things about "hums":
-light kits can vibrate, a glass dome will amplify the natural hum from a motor
-low-profile fans are worse because the motor assembly is direct-mount to the box, whereas a standard fan on a rod isolates the motor, and reduces the noise from resonating throughout the fan unit & ceiling.
For a $125 Hunter fan, it lacks noise suppression, which is a trade-off when the house has low ceilings.
