Bathroom exhaust fan

I am trying to replace my bathroom exhaust fan. There is no light with it. The problem I have is I was trying to cut off the electric to it at the electric panel but I flipped every switch and it never turned off. The only one I did not switch off was the main. How do change it and is there a potential danger in this situation if it is not on a breaker?

No switches just breakers in the breaker panel. If you used a non contact tester your results are meaningless. If you mean the fan didn't stop running or you used a multimeter then first turn off all 20 amp single pole breakers at the same time. If it is still on turn off all the 15 amp single pole breakers off also.

The reason for turning them all off is to determine if one circuit is accidentally cross connected to another.

if you however you used a non contact tester first you must find a real way of determining if it is off when you flip breakers. Most exhaust fan motors plug into a standard receptacle built into the fan housing. You can unplug the fan and plug in a light if the fan doesn't work. Wall switch must be on for testing.

I did not use any testers. I just switched the fan on and listened to it run while flipping the switches at the panel. The fan kept running no matter which switch I flipped. I will try doing all at once to see if that works. Or I will just flip the main off if I have to. I just bought the house a week ago and no switches are labeled on the panel so I am still trying to figure all of them out

Just a reminder they're called breakers not switches. Let us know your results.
