Generic 3-speed ceiling fan circa 80s or 90s makes buzzing noise at highest speed. I don't know what brand this is, I don't have a model number, but hopefully it's a similar enough widespread design.It makes excessive motor noise at the highest speed only. It sounds likely electric, like a buzzing, and it's definitely not the usual "motors just make noise" thing. It's something intrusively loud, and the noise seems to come and go some days, due to indeterminate factors.It's also not balanced, and is not grounded properly, but I don't know how likely that is to cause what I'm hearing.
>>2966103OP here.Actually, the grounding might be fine. It's mounted to grounded conduit, and only the ground wire isn't screwed down under the cap.
are you at all technically inclined? if so you can test the run capacitor with a multimeter that also tests capacitance (should be a black box with 2 to 5 wires coming out of it) 90% of the time the diagram of what values each capacitor should be
>>2966105>are you at all technically inclined?Yes, but I don't have a multimeter that can test capacitance. I'll have to get one, I guess.
Depending on the noise, it could be a failed bearing.
>>2966103are the blades sagging from gravity pulling on them ?
sometimes the screws are loose and it makes that kind of noise
>>2966279A little bit.
>>2966303I had a fan that the blades sagged and they were uneven so it was making it wobble from being out of balance bend them back up so they are even and see if it gets any quieter
>>2966380I will when I figure out how to bend the wood back up without making it worse.
>>2966390I just held the center of the fan and pushed up on the outer edge of the blades they bend way easier then they look
First thing I would do is dissassemble it and clean out everything inside. I've seen old ceiling fans with the motor area choked up with accumulated dust and it makes them not operate so well.
>>2966403It's wood, they're not gonna conform like metal.My plan was taking the blades off and ironing one side, so hopefully the wood would contract more on the top and pull the blades back up.
>>2966404That is a good point, it is dirty on top from being in a greasy kitchen for decades. We didn't even buy it new, it was trash picked for free about 25 years ago.
>>2966404>>2966469*so who knows what else it was subject to, and I wasn't living here all those 25 years, so I don't remember if it always acted like this when we had it.
>>2966103record the sound and upload it to vocaroo then post the link here so we can hear it
>>2966467Mine had wood blades also it was the metal brackets that mount the blades to the motor the were sagging
>>2966103Ima say bad capacitor.
>>2966103Put a Tesla motor in it
