Ball bearing in ceiling fan.

Faulty bearing causes noise in ceiling fan. Ceiling fans usually run smoothly and quietly but sometimes you may notice a ceiling fan noise that ruins the peaceful surroundings. Ceiling fans circulate air to make the room more comfortable all year round. My ceiling fan would sometimes not start and making rumbling sounds bearings i did not want to replace or tear down so lifted plastic cover on top and liberally sprayed machine oil over exposed bearing through slots underneath wd 40 this has cured problem perfectly just dry bearings would probably be better to use spray grease if you have cheaper than new fan or bearings and only a few.

If the ball bearings are to blame you may need to lubricate them to reduce the friction and quiet the noise which is often described as a rubbing or humming sound. They also give the air conditioning and heating system a break by maintaining a comfortable temperature throughout the room or home.
