hi can anyone advice me,i have been using metal blades ceiling fans in my 3 bedrooms but 2 of them has started to made a very loud noises everytime we use them it seems to be coming from the motor but i don't have that problem in my other bedroom i don't want to call for service as i find it expensive so does anyone know if there's anyway to fix it myself?

or can anyone share your experiences who ever have a same problem like mine?

It's better to leave it to the technician.

Not easy to drill an 8mmX40mm hole for the expansion bolt with your domestic mansonary drill.

You don't want to save $50 and have a ceiling fan crashing down on you.

you need a measuring and ladder to make sure you get the correct sized. Measure before you buy.
