--- title: "Fulgor Milano radiant cooktop showing FL" description: "What FL means on Fulgor Milano radiant cooktops, what to check before booking, and when it is not a failure at all." url: "https://cooktoprepair.center/error-codes/fulgor-milano-s600-fl/" --- # Fulgor Milano radiant cooktop showing FL FL is a keyboard error tied to ambient light. ## What FL actually means. FL is a keyboard error tied to ambient light. Fulgor explains that strong light shining directly over the touch area at power-up can spoil the sensors' start-up calibration and leave the controls unresponsive. Fulgor Milano cooktop display What to do when FL shows on the cooktop ### Kind of code Touch controls and keys A key on the glass was held down too long, pressed with nothing there, or stopped answering altogether. Water, a spill or a pan resting on the key strip is ruled out first, then the touch board and its ribbon cable. If a zone keeps heating while the keys are dead, switch the cooktop off at the breaker. ### Usually leads to Touch control repair Glass touch keys and sliders that ignore a finger, start zones by themselves or stay locked, traced to the keys, the control board or the lock setting. ### Shows up as Cooktop Controls Unresponsive Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element. ### Make Fulgor Milano An Italian maker of built-in cooking appliances sold through US luxury dealers. ### Source Fulgor Milano S600 radiant cooktop use and care manual (archived) Fulgor Milano S600 radiant cooktops (F6RT24, F6RT30, F6RT36); read from the archived use and care manual.

Shade the control area from direct sun or a bright lamp. If it comes back, it needs a visit. ### Can sunlight really stop my Fulgor Milano cooktop working? Fulgor says strong direct light over the controls can affect them, especially when power returns. Shade the panel and restart. ### Why does FL only show in the afternoon on my Fulgor Milano? If the sun reaches the counter at that time, it may be shining straight on the touch area. Try blocking it before booking a visit. ### Why does FL on a Fulgor Milano S600 often appear when power comes back? The touch sensors calibrate at start-up, and strong light shining directly over them at that moment can throw the calibration off. Shading the controls and cycling the power lets them calibrate again. --- **[Read on the site: Fulgor Milano radiant cooktop showing FL](https://cooktoprepair.center/error-codes/fulgor-milano-s600-fl/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
