Four L letters across the displays mean the ILVE key-lock function is active: all zones are switched off and cannot be started by accident. It is turned on and off by turning two knobs counterclockwise together while every knob is at 0, and OF shows when it is released.

Nothing has worn out, and no part is needed. ### Usually leads to No repair With every knob at 0, repeat the two-knob counterclockwise turn described in your manual until OF appears. ### Shows up as Range Control Panel Not Responding The touch keys or knobs on the range do nothing, only some keys work, the display is blank or frozen, or it beeps without starting. ### Make ILVE A family-owned Italian manufacturer of pro-style ranges in gas, dual-fuel and induction versions, often with two ovens. ### Source ILVE Nostalgie II Manual Nostalgie II and Majestic II induction ranges; the manuals name different knob pairs in two places, so check the page for your model. ## Before you book, in this order.

The range was set right without a new part.

With every knob at 0, repeat the two-knob counterclockwise turn described in your manual until OF appears. ### Why won't any zone start on my ILVE while LLLL shows? The key-lock switches every zone off and blocks the knobs. Release it with the same two-knob turn and the zones respond again. ### Which knobs unlock my ILVE induction range? The manuals mention two different knob pairs in different places, so try the pair shown for your model with all knobs at 0. If neither pair works, book a visit. --- **[Read on the site: ILVE induction range showing LLLL | RangeRepair.center](https://rangerepair.center/error-codes/ilve-llll/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
