Lights Flickering, Dimming, Brightening, and Buzzing


I'm wondering if it could be the furnace humidifier I had serviced about a month ago. That was the first place I heard the buzzing from. My furnace guy changed the filter on it and being it's a tight squeeze where it's at. You almost have to take the whole thing off to get the filter in it and maybe when he put it back together, something happened. It does have an electrical line going from it to the furnace and there's what looks like a pump or solenoid type of device to bring the water in from the cold water pipe right next to it.

Power company is back out, this time with a big truck. Said they're gonna check a few things outside and that they're pretty sure it's an open neutral somewhere and that if it's outside, they'll fix it. So, we'll see.

Power company came and did their thing the other night. They did something where the power comes into the house and something out at the pole. Said that should take care of things, but if not, then I have to bring in an electrician and hunt down the problem. Whatever they did, didn't work. Still have some lights flickering. still have some buzzing every now and then. It's not continous, and you have to get real close to hear it. Back up a foot and you can't hear anything. Tomorrow, my furnace guy is coming to check the humidifier hookup to see if that's ok. Sister-in-law said she would try and get her sisters husband, an electrician, to come over and check it out. Wherever it is, it's affecting lights in the bathroom, kitchen, and family room. Alot of flickering today, but it's also very windy out and maybe that doesn't help.

Take the opportunity to tighten up all the connections and set screws in the panel. (Omit the big lugs with the fat wires for now; a really experienced person should tighten those). If a connection is already tight, loosen it a quarter turn and retighten. Turn off each breaker just before tightening up the screw holding the circuit wire. Do not use tremendous force.

Are there some incandescent lights on each side of the 120/240 volt service that do not flicker?

Furnace guy came and checked out the humidifier. Said it could be a bad solenoid on it and that that would cause a buzzing and would definitely send the noise through the cold water pipe, which it's hooked up to. And he also said it could be sending enough current through to make it buzz, but not enough to cause any harm. He's going to change the solenoid out and we'll see what happens. It could be very well what he said. Humidifier is probably about 20 yrs old or more. Stands to reason a part could go bad in that time.

Just thought I'd give an update on the situation. Furnace guy came, changed the solenoid on the humidifier, no more buzzing, no more flickering lights. Thank you all for your concern and advice. I'm glad it wasn't more serious than what it was.
