You can use any capacitor of value about 3.3mF to about 6.8mF with an AC voltage rating of about 230 to 250 volts.
These are the bipolar type capacitors and is generrally available at all electrical or electronic spare parts shops.
Hope this helps.

After 8 months, fan will not start. Check 3 speed switch..OK, checked motor coil...OK check 110V supply...OK 5 microfarad start capacitor fails to charge/discharge. Need replacement, but can not find...

The latest Jameco electronics catalog ( has a 5 uF 370 volt motor-run capacitor for $1.95. It may however, be too physically large to fit in the motor case. Hope this helps!

Hi, I have a problem with bionair widow fan 2300, it´s the R1 RESISTOR, but the over heating erase the color code of the resitor, you can help me?...sorry for my english

There is a major problem with the fan's electronic board. There is most likely a shorted capacitor, or some sort of fried transistor somewhere. depending on your electronics know how, try troubleshooting the circuit starting with it's power supply/input. but depending on the price of the fan, and the amount of aggrivation, I would just get a new one. Remember, most of the newer appliances today are ment to only last a few years, then die. I don't care what it is. all the companies want to do is make them as cheaply as possible, so they can sell more of them, and make more money. so don't be surprised if you can't fix it. some things are just not fixable.

My lakewood HV18 just stopped. Spinning the shaft

I think you need to buy a new fan. Unless this thing cost several hundred dollars it isn't worth rewinding and a capacitor isn't likely to cause it to stop working, the cap is for STARTING it spinning anyway and sometimes they are used to HELP it run better, but it will try to run if you spin it and since your's does nothing, more than likely the windings are gone.

Motor stopped running. There is apart encased in black housing with the nomenclature 3.5uF-U/250WV.AC. Is this a capacitor and should it be replaced?

Yes, that is a capacitor...exactly where is it located? It could be a starter capacitor. Try this, plug it in and turn the switch on then push one of the fan blades in the direction it would normally turn; if the fan starts up then it is definitely a starter capacitor issue. Unless you have extensive electrical/electronic experience, I would advise you to not try to repair this on your own, rather bring it to a reputable appliance repair shop in your area.

Casablanca fan only runs at highest speed

When I turn on any of the fan speeds fan does not come on. When I remove the blades and turn on the ceiling fan on and give it a push the fan stays running. What could it be?

It sounds like the electronic controls have put the fan into "breeze mode". The fan turns slowly then is supposed to surge back to high. Some people love this feature for some reason...
Disable breeze mode via your remote (its the button with the stacked ~'s).

A bad motor wouldn't rotate at all. The only other problem might be the motor's running capacitor. If you can start the fan in either direction (give it a hand spin in the opposite direction of rotation) you have a bad capacitor...and you can find a replacement anywhere (Radio Shack).

Hunter ceiling fan remote doesn't work

counterclockwise for cooling. This blows air down. The electronics board maybe burned out. There is a small fuse and capacitor in the fan. You can buy parts for this fan.
