You'll get two valuable pieces of info from this. 1  How long it takes your oven to preheat to 400ÂºF and. 2  Whether your oven is indeed giving you 400Âº and not 385Âº or 406Âº. The differences are miniscule but at least you'll know if your oven runs a little hotter than normal, less hot or right in the money.
