My pedestal fan Hampton Bay FS 21-45 stopped working. Power seems to be running from the switch to motor. How can I find out /measure/ if motor is dead? I don't want to throw it away. Thanks.

I don't know for sure what you're asking. But if you have power to the motor, and the motor is inop, then I would say the motor is bad or has popped it's own overload/overheat protection... which that fan probably doesn't have.
