Without small details, I have nothing to base my opinion on.
Hey, this has nothing to do with computers, but rather a circuit inside of an electronic device. There's a small black box on the circuitboard which clicks a LOT at random intervals. the circuitboard is very small, used only for an on/off switch. This is inside of an electric cooler, the on/off switch simply turns a fan on to cool beverages inside of a cooler. The Red and Black wires of the fan go to the board, and so do the wires from the switch. I don't know why the board is necessary, it's only 1"x2" and you'd think the on/off switch would do the job on it's own. think i can remove the board altogether and just splice the wires of the fan directly to the switch? What is that black box on the board that keeps clicking!?
