What H t
actually means.
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 cooktopKind of codeTemperature 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 toInduction 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 asCooktop 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.

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.
Lower the power or move pans to the rear zones and let the cooktop cool.
Make sure nothing blocks the space under the cooktop.
If H and t show up during ordinary cooking, book a visit.
Still there?
It usually turns into induction board and coil repair. Book with the code and the model number.
What not to do
H and t together are not the plain residual heat H that shows after switching off. This one appears while you cook and limits the front zones.
What you may
notice with it.
The cooktop problems H t tends to arrive with. Answer these at the cooktop before anyone is booked.
