Ceiling fan spinning slow. How hard is it to change the capacitor?

Fan in the living room spins very slow even when turned on full speed. From what I've read, it seems like I need to change the capacitor. Has anyone done this, and if so, how difficult is this? I'm not a handy man at all when it comes to electrical stuff. I've already turned in my mancard for that.

What do they cost? Any help is appreciated.

Change the fan out. They aren’t expensive and come with a new capacitor.

I honestly have no idea but you are likely going to need to give more details on the fan model. It could simply take the fan apart, un plug the capacitor, and plug in the new one. Or it could be on a control board and you have to solder it.

What makes you think the brushes on the motor aren't bad?

For the cost of a replacement *anything* on a fan, might as well spring for a new one.

I guarantee you that changing the fan is a lot easier. The small amount of money you save between the cost of a new fan and a capacitor is not enough to make up for the work and aggravation of trying to change it out.

Just depends on how easy it is to access the motor housing. I have a few of the flush mounts that would require me to take all the blades off to access the capacitor. The one in my bedroom was accessible after removing just a couple of screws. It's fairly new, so was worth replacing the $5 capacitor vs. the $150 fan. But rather than going through the manufacturer, I bought the capacitor on ebay based on the old one's specs and just snipped the old one off, spliced in the new one.

If you're dealing with a rickety old $50 flush-mount, just toss it. Ceiling fans really suck nowadays and are pretty disposable. I'm not even sure every ceiling fan motor uses a capacitor.

high torque motors use capacitors.

portable fans and ceiling fans use shaded pole motors that dont use capacitors. most likely the bearings are bad or the speed switch is bad and either way, it may soon start smoking or catch on fire.

most of the switches on those fans are not the same as generic fan switches so if you buy a switch and replace it 1 out of 3 times the fans bursts into smoke and gets instantly fried.

just replace the fan in other words, home depot has them from $100 to $50 to $30 depending on how nice you want it to look

Just make sure you put it in correctly.

Depends on the brand generally cheap fans are harder to repair as they are toss away models.

I will probably just get a new fan after seeing so many say that. So thanks

Come here when you're ready, and I agree, replace it.

"Now, how difficult is it to do?"

Surely you have a friend that can assist. You can get the piss shocked out of you if not careful.

I've changed dozens and it's not too hard.

This.
Most likely mechanical issue. Anything electrical won't cause it to just slow down
