Place an induction-compatible pan, one a magnet sticks to, on the zone. ### Why does my BlueStar show u when I put a pan down? The zone does not accept that pan, usually because it is not magnetic or too small. ### Is U the same as u on BlueStar? BlueStar points both to the Keep Warm section as well. A u with no warming set usually means the pan is not recognized. ### Can a pan base that is too small cause u on a BlueStar TOUCH induction cooktop? It can, since BlueStar lists a base diameter that is too small among the reasons for u, along with cookware that is not induction-compatible. Use a pan with a wider magnetic base and try again. --- **[Read on the site: BlueStar induction cooktop showing u | CooktopRepair.center](https://cooktoprepair.center/error-codes/bluestar-u/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
