Fr on a Viking Designer electric cooktop is a relay error. Relays switch power to the radiant elements, so this code points at the switching side rather than the keys or the display. Viking cooktop display What to do when Fr shows on the cooktop ### Kind of code Radiant elements A ribbon element under the glass, or a coil on an older top, did not heat the way its control asked, or kept heating past the setting. The pan, the infinite switch or touch relay behind it and the wiring to the terminal block come first; the element and its temperature limiter follow. A zone that will not switch off means the breaker goes off before anything else. ### Usually leads to Radiant element repair Zones under a smooth glass cooktop that stay dark, heat weakly or cut out, traced to the ribbon element, its limiter or the relay that feeds it. ### 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 Viking A Mississippi maker of pro-style kitchens whose US site lists both cooktops and rangetops. ### Source Viking Designer electric cooktop use and care manual, Error Codes Viking Designer built-in electric cooktops with touch controls, per the use and care manual F20699. Other Viking cooktops use different displays. ## Before you book, in this order. Each step comes from Viking's own guidance for Fr on its cooktops. Follow it to the end: the last card says whether this is a visit. 01 Switch the cooktop off at the breaker if any element stays hot after being turned off. 02 Otherwise, cut power for a minute, restore it and test each element. 03 Book a visit if Fr returns. ### Still there? It usually turns into [radiant element repair](https://cooktoprepair.center/services/radiant-element-repair/). Book with the code and the model number. ### What not to do Fr is not a key problem, and it does not by itself mean an element has burned out. It points at the relays that switch power to the elements. ## What you may notice with it. The cooktop problems Fr tends to arrive with. Answer these at the cooktop before anyone is booked.

Switch the cooktop off at the breaker if any element stays hot after being turned off. If it comes back, it needs a visit. ### Can a Viking relay error leave an element on? A relay that sticks can keep power on an element. If an element will not switch off, turn off the breaker and book a visit. ### Why did only one element stop working before Fr showed? Relays serve particular elements, so a failing one shows up on those first. ### Will the other elements keep working on a Viking Designer cooktop with Fr showing? No, Viking says the control stops all the heating elements when it declares a code, and Fr is no exception. Even if only one relay is involved, the whole top waits until the error clears. --- **[Read on the site: Viking electric cooktop showing Fr | CooktopRepair.center](https://cooktoprepair.center/error-codes/viking-fr/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
