They are prone to failure, and the symtoms are that they quit when they get hot and then they work again after they cool down. It's not an expensive item, about $25, and even if it isn't that it doesn't hurt to have a spare,cause sooner or later your gonna need one. Although I'm 90% sure that it's your problem.
