I have been wanting to check my oven temp out of cuiousity. I haven't had any problems so I didn't really want to go out and buy something just to appease my curiousity. I was wondering if anyone knows if I can use a candy thermometer, don't want to ruin it. And if I can, should I just place it on the rack for a few minutes? Any thoughts would be great.

To each its own. You'll need an oven thermometer to check your oven temperature.

for me, an actual oven thermomoter is a great tool to have. I've found that my oven is accurate when set at some temps, and not so accurate when set to others, so the thermomoter helps me adjust each time it's needed.

I didn't spend much, I think about $5 and it stays in the oven. I wouldn't want to risk breaking a candy thermom. in the oven.

I agree.

Purchase a good quality oven thermometer.
I went with a cheap grocery store brand first, and it was a waste of money! And.......I lost several cakes too.

After spending a few extra dollars for a good one, I was able to calibrate my oven and I found it ran 25 degrees cool!
I just leave mine in the oven all the time.
