Thanks

Well, when you have the resistor off the board, just hook 6 VAC to it and see if the fan runs. The board will actually be receiving a chopped waveform from the AC regulator when it's installed, it uses a triac to adjust the power to the smoke unit. For just testing the fan, when the smoke resistor isn't on the board, only the fan power supply gets power, and we just want to see if the fan spins quietly.

Thanks for the updated information. For future reference, if I am testing a smoke unit with the resistor installed, what voltage would I be using?
