Fr is a relay error on the S600 radiant cooktop. The relays switch power to the radiant elements, so the control stops heating when it cannot trust one. Fulgor Milano 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 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.

Cycle the power at the breaker once. If it comes back, it needs a visit. ### Can a relay problem keep a Fulgor Milano element on? A relay that sticks can leave an element heating when it should not; if an element will not turn off, switch the breaker off and book a visit. ### Is Fr on a Fulgor Milano cooktop repairable? Yes; relay errors lead to a board-level repair rather than a new cooktop in most cases. ### What do the relays do on a Fulgor Milano S600 radiant cooktop? They switch power to the radiant elements. When the control cannot trust a relay, it stops all the heating elements and shows Fr. --- **[Read on the site: Fulgor Milano radiant cooktop showing Fr](https://cooktoprepair.center/error-codes/fulgor-milano-s600-fr/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
