the hooks BROKE? what the hell man. it's not worth the risk of trying to fix it at this point because you are going to need those rails no matter what. easily you may have damaged it, and even if it did work (as in testing it at a low temperature), it may be producing faulty temperature results. also yes it doesn't work correclty if it touches the oven metal. unless you had another temperature gauge of some sort to make sure it's reading right, and free floated the metal wire (very dangerous because if it gets in a bad position again you can BURN FOOD / BURN HOUSE DOWN), it still may work, but this is a lot of effort and not worth the risk.
