For some reason food.com ran this suggestion last year on checking over temperature without a thermometer, and it showed up on the inter-tubes today.
Ingredients:
granulated sugar
aluminum foil (optional)
Directions:
1
 To test if your oven is running cold:.
2
 Preheat oven to 375°. (186° C.).
3
 Place a small amount of granulated sugar in an oven-proof dish or on a cookie sheet lined with aluminum foil.
4
 Place in oven for 15 minutes.
5
I f your oven is calibrated correctly, the sugar will melt.
6
 If your oven is running cold, the sugar will not melt.
7
 To test if your oven is running hot:.
8 
Preheat oven to 350°. (177° C.).
9
 Follow the same procedure as above.
10 
If your oven is calibrated correctly, the sugar will not melt (although it may brown a little).
11
I f your oven is running hot, the sugar will melt.
12
 Note: ovens do not maintain a constant temperature, but cycle above and below it, so it is possible that the sugar may melt at 350° if your oven is correctly calibrated but has an extreme cycle (15° F, 8° C.).
Use a thermometer.
