I purchased a Star waffle maker in April and now it will not heat up who do I talk to about this problem?

Nearly all appliances that use high heat in their operation such as your waffle maker, coffee makers, toasters, use a thermal fuse to prevent fire. Unfortunately, these fuses are all coming from China and are very poorly made. Additionally, they are mostly welded to their mounts since the heat to which they are exposed is too high for soldering or fuse holders and are not user replaceable.
You will need to ship back your waffle maker to the mfr. for repair and you should have plenty of time left on your warranty.
