Clean and dry the touch area, then cut power at the breaker for a minute. If it comes back, it needs a visit. ### How is Fb different from FA on my Viking cooktop? Viking calls FA a key error and Fb a keyboard error, which suggests one key versus the keyboard as a whole. Both are touch-control problems. ### Can water on the glass cause Fb? Moisture can confuse touch keys, so wipe the area dry first. If Fb stays, the keyboard needs testing. ### Should I press harder on the keys when my Viking Designer cooktop shows Fb? Extra pressure will not help, because Fb is a keyboard error found by the control's self-check. Clean and dry the glass, reset the power, and book a visit if Fb stays. --- **[Read on the site: Viking electric cooktop showing Fb | CooktopRepair.center](https://cooktoprepair.center/error-codes/viking-fb/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
