There is a manual switch fan over my stove at home. Last night, while I was in another room and nobody else was in the kitchen nor was anything cooking at the time (it does not have an auto sensor), it turned on by itself. How can this happen? I'm baffled, stumped, mystified.

Look - what makes a switch work? The opening/closing of a circuit. Nothing more. So I'd look at the switch on that fan, open it up, take it apart, and see what's up. Something's opening the circuit. Might be a worn toggle switch that's not fully holding its position (it just take a little contact to open a circuit), might be some crud up inside there that's f-ing things up, who know? But it's something in the switch. Has to be.

If it ain't, do you dig Sigourney Weaver?

Enough crud to move a rocker-type switch?

The switch doesn't have to "move", the circuit just needs to be opened. Something can be loose on the inside that you can't see from the outside.

Take it apart, open it up, and see what's there. Something's loose.

Actually, to be technical about it, if something is on, then the circuit is considered "closed". And "open" circuit means there's a break in the line somewhere (like a switch turned off).

But I here what you're saying.

Was the rocker actually in the "ON" position? Those things are spring loaded and it could be that the last time you turned if off, you didn't turn it totally off and it sprung back to the "ON" position.

Yea, I tried toggling with it last night. It wouldn't get stuck in the middle. You need a solid nudge either way.

Y'all musician types might also mention flipping the circut breaker off for the room he is in, before taking apart in any way the fan switch.....
