Wipe the touch area clean and make sure nothing shades or covers it. If it comes back, it needs a visit. ### Can bright light or a shadow cause FL on my Viking cooktop? Viking says the self-check looks at ambient light conditions around the keyboard. Covering or shading the keys can upset it; if FL persists with the area clear, the keyboard needs testing. ### Is FL a keypad replacement? Often it ends in one, but clean, dry keys and a reset come first. ### What is a Viking Designer electric cooktop checking when it shows FL? Its self-check looks at keyboard function and at the ambient light around the keys, and FL means the light part of that test failed. The control then stops all the heating elements until the check passes. --- **[Read on the site: Viking electric cooktop showing FL | CooktopRepair.center](https://cooktoprepair.center/error-codes/viking-fl/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
