The underlined u is Samsung's pan detection signal on induction models. Something about the pan, its size, its metal or where it sits, keeps the zone from heating, and after a minute without a fix the zone gives up and switches off. Samsung stove display What to do when Underlined u shows on the stove ### Kind of code Stovetop elements A burner on an electric or induction stovetop did not heat the way the knob or key asked, heated with nothing set, or ran hotter than the setting. The pan, a lock left on and the switch behind the knob are checked before the element under the glass, its limiter or an induction board is changed. If a burner keeps heating after it has been switched off, turn the stove's breaker off before anything else. ### Usually leads to Glass stovetop repair Smooth glass stovetops on electric and induction stoves with a cold circle, a cracked or chipped top, or a hot-surface light that stays on, repaired under the glass or with a new top. ### Shows up as Stovetop Not Heating The burners on an electric, glass or induction stovetop stay cold or warm up only a little, sometimes all of them and sometimes two on one side, while the oven below may still work. ### Make Samsung The Korean electronics maker, whose stoves come in gas, electric and induction models, many app-connected. ### Source Samsung support: range or wall oven error codes Samsung induction models only, per Samsung's range and wall oven code page. ## Before you book, in this order.

Slide the pan so it sits in the middle of the printed circle. If it comes back, it needs a visit. ### Why does my Samsung induction stove show an underlined u with my new pan? Many stainless and aluminum pans are not magnetic enough for induction. Test the base with a magnet; if it does not hold, the zone cannot heat it. ### One zone on my Samsung shows the underlined u with every pan. What now? If the same pan heats on the other zones, the problem is that zone's coil or its board. Book a visit. ### Why did my Samsung induction zone turn off by itself after a minute? Samsung turns the zone off after 1 minute if the pan problem is not fixed. Move or change the pan and set the zone again. --- **[Read on the site: Samsung induction stove shows an underlined u](https://stoverepair.center/error-codes/samsung-underlined-u/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
