The base of the Kitchen Thermometer is magnetic. To test the strength of the magnet, try placing the Kitchen Thermometer base on top of the magnetic probe wrap. If your Kitchen Thermometer magnetizes to the probe wrap, then the surface you are trying to stick the base to is not an ideal magnetic surface. Use the magnetic adhesive disc, included with your purchase, to create a mounting point for your Kitchen Thermometer.
Please remember: The Kitchen Thermometer base is not designed to withstand high heat exposure and it must only be mounted on a cool surface. If the surface is too hot to touch, it's too hot for the Kitchen Thermometer!
