    Generally any AC rated start capacitor should work. 300v in the original could have been a bit of overkill.

    If the original was rated for 300VAC, and it failed, 250VAC is most likely going to fail sooner.

    I'd use this, instead.

    The manual shows it as a 120v fan so a 240v cap should do the trick fine. As long as it is motor run rated.

    And, yet, the 350 volt unit failed...

    Depends on the manufacturer and do they provide AC motor rated capacitors, the N.A. run caps I use I don't recall a failure.

    Incidentally for the past few decades many purchasers of imported small machines of Chinese origin that have a 1ph induction motor spindle usually have a capacitor failure withing a year or two of operation.
    Something to do with the seeming inability for them to manufacture a AC rated start capacitors.

    You can get the Lasko box fan capacitor from here.
    Also this is available at any electric shop or hvac shop would have them.

    I received the c
    I ordered this capacitor and it has a red and black wire. I have attached a photo of the current fan and capacitor. Which wire is the red and black on the old fan setup? I will cut them and attach the new capacitor.

    Gee... if we only knew your location, we would offer you better targeted choices.

    The leads of the new one wire the same as the old one, colour does not matter, there is no polarity to the AC motor cap.
    As long as it is a AC motor type.

    I am still open to suggestions. I need another capacitor for a similar box fan.

    I replaced the capacitor and that did not change anything. I decide to look at the thermal capacitor. I bypassed it and I get a low buzz from the motor but it does not spin the fan. It sounds like it is try to turn but nothing. I cleaned and oiled it. It seems like it does not have enough power to turn.

    Any advise?
