Need Circuit expert!

by mtrodrig84 / May 2, 2007 10:52 AM PDT

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!?

Without small details, I have nothing to base my opinion on.

If there are simply 2 wire going to the switch and 2 wires going to your fan, then yes you can. Make sure there are no capasitors or transistors. You could cause a short. send me a pic of it @ kdodd92@yahoo.com and ill tell you what i think.

Thermostat ?

Without more details, my WAG would be that it's a thermostat.

(Providing more details gets you a better answer.)

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
