If the fan worked top earlier, it may be that the capacitor/capacitors prefer changing. First, make optimistic that there is not a mechanical problem e.g. undesirable lubrication, buildup of airborne dirt and dust, airborne dirt and airborne dirt and dust and so on. by way of turning the blades by way of hand (make optimistic potential is off first) in case you may desire to alter a capacitor, use the comparable fee it fairly is interior the unit with the aid of fact the motor substitute into designed to artwork with specific values. in simple terms a notice, I even have replaced capacitors on a pair of those followers (chop up capacitor automobiles.) they're usually twin contraptions for the fee administration. What now and returned occurs is the fan is reversed jointly as this is working and the capacitor fails. you may tell with the aid of fact the case cracks.
