Long use at full power in a warm kitchen can leave the electronics unable to cool. Smeg's ceramic cooktops then cut power to the front zones and flash H and t on the display, and cooking can continue once temperatures fall. Smeg cooktop display · also shown as Ht, H and t What to do when H t shows on the cooktop ### Kind of code Temperature and overheat sensors A sensor under the glass or on a board reported a reading the control rejected, or heat climbing past the safe limit — often after an empty pan was left on a zone. The zone is allowed to cool and a loose sensor plug is ruled out before the sensor, the coil assembly or the board is blamed. A top that keeps getting hotter is switched off at the breaker first. ### Usually leads to Induction board and coil repair Induction zones that stop sensing pans, cut out, buzz or show codes, traced to the power boards, the coils, their sensors and the links to the controls. ### Shows up as Cooktop Element Not Heating A coil stays black, a radiant ring under the glass never glows, or a zone warms so weakly that a pot of water will not boil. ### Make Smeg An Italian maker known for its retro styling, whose US catalog includes built-in cooktops. ### Source Smeg ceramic cooktop manual (SEU304EMTB) Smeg SEU ceramic (radiant) cooktops; read from the manual Smeg links from the SEU304EMTB product page. ## Before you book, in this order. Each step comes from Smeg's own guidance for H t on its cooktops. Follow it to the end: the last card says whether this is a visit. 01 Lower the power or move pans to the rear zones and let the cooktop cool. 02 Make sure nothing blocks the space under the cooktop. 03 If H and t show up during ordinary cooking, book a visit. ### Still there?

Lower the power or move pans to the rear zones and let the cooktop cool. If it comes back, it needs a visit. ### Why did the front zones of my Smeg ceramic cooktop stop heating on a hot day? Smeg says high room temperature makes it harder for the electronics to cool, and the front zones are cut first. Let it cool; if it happens in normal conditions, book a visit. ### Can I keep cooking on the rear zones while H and t flash? The cut applies to the front zones first, so the rear zones may keep working. If the display moves on to HItE, every zone has been stopped. ### Which zones does H and t switch off on a Smeg SEU304EMTB? The front cooking zones: Smeg's device cuts their power when the electronics cannot cool, and the display flashes H and t. Once temperatures drop back below the safety levels, those zones can be used again. --- **[Read on the site: Smeg ceramic cooktop flashing H and t | CooktopRepair.center](https://cooktoprepair.center/error-codes/smeg-ceramic-ht/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
