On the SKS dual-fuel rangetops, the induction control reports its errors as F33 through F45 on the knob's LED and beeps. SKS gives one meaning for the whole band, an electronic control error, and asks you to record the number if it comes back. SKS cooktop display · also shown as F33, F45 What to do when F33~F45 shows on the cooktop ### Kind of code Induction power and coils An induction zone could not drive its coil as the board planned: no pan was detected, the current ran too high or too low, or the power stage reported trouble. The pan base, the supply voltage and a clogged air intake are checked before the coil or the power board is replaced, and a top that trips its breaker is left switched off until then. ### 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 SKS Signature Kitchen Suite, LG's luxury label, lists gas and dual-fuel professional rangetops, some with induction and sous vide. ### Source SKS SKSRT360SIS/SKSRT480SIS rangetop owner's manual SKS dual-fuel pro rangetops SKSRT360SIS and SKSRT480SIS, which combine gas burners with an induction section and a sous vide module. The codes appear on the LED ring of the knob. ## Before you book, in this order. Each step comes from SKS's own guidance for F33~F45 on its cooktops. Follow it to the end: the last card says whether this is a visit. 01 Turn the induction knob to the central OFF position to clear the display and stop the beeping. 02 If the code returns, write the number down, turn the knob to OFF and book a visit. 03 Cook on the gas burners only until the induction section has been checked, if the code keeps coming back. ### Still there? It usually turns into [induction board and coil repair](https://cooktoprepair.center/services/induction-board-and-coil-repair/). Book with the code and the model number. ### What not to do These codes come from the induction section only. The gas burners on the same rangetop may keep working normally. ## What you may notice with it. The cooktop problems F33~F45 tends to arrive with. Answer these at the cooktop before anyone is booked.

Turn the induction knob to the central OFF position to clear the display and stop the beeping. If it comes back, it needs a visit. ### Why can I still use the burners when my SKS rangetop shows F38? The F33 to F45 codes come from the induction control, which is separate from the gas burners. Leave the induction section off and book a visit if the code returns. ### Why does SKS ask me to write down the number? SKS publishes only the band, so the exact number is what tells the technician where to start. ### Where does the F33 to F45 code show on an SKSRT480SIS rangetop? On the LED ring of the induction knob, together with beeping. Turning that knob to the central OFF position clears the display. --- **[Read on the site: SKS rangetop induction knob showing F33 to F45](https://cooktoprepair.center/error-codes/sks-f33-f45/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
