Question ceiling fan hum

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.

I doubt this has anything to do with the circuit. Try a Hunter fan next time.

And about the hot/neutral wires in the extension cord? (Just so I can try something before heading back to the store.)

Thanks

Whcih wire is which in an extension cord is not important for your experiment.

Black is hot, white is neutral, green is ground.

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'm still here so far -- thanks for your concern! Fan is still humming from duplex outlet power, so don't think it's a wiring thing. I'm going to take the original advice to go with a Hunter fan & let you know how it goes.

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.
