An L in the middle of the control display means the induction top has been locked by turning the two left-hand knobs counterclockwise together. The oven keeps working while the top is locked. AGA range display What to do when L shows on the range ### Kind of code Mode, not a failure Something the range was told to do, or a state it chose on purpose — a control lock, a Sabbath setting, a demo mode that lights the display but never heats, a pan warning on an induction zone. Nothing has worn out, and no part is needed. ### Usually leads to No repair With all zones off, turn the two left-hand knobs counterclockwise together and hold until L disappears. ### 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 AGA A British cooking name, owned by Middleby, that sells cast-iron heat-storage cookers and more conventional dual-fuel and induction ranges in the US. ### Source AGA Elise 36 Induction Owner's Guide Elise and Mercury induction ranges; an A may flash while the lock is set, which the guide calls normal. ## Before you book, in this order. Each step comes from AGA's own guidance for L on its ranges. Follow it to the end: the last card says whether this is a visit. 01 With all zones off, turn the two left-hand knobs counterclockwise together and hold until L disappears. ### Cleared? The range was set right without a new part. If the same message comes back while a burner or the oven is in use, or the range cuts out again, treat it as a new problem and book it. ### What not to do L is not a failure of the controls. The zones are refusing to start because they were locked on purpose. ## What you may notice with it. The range problems L tends to arrive with. Answer these at the range before anyone is booked.

With all zones off, turn the two left-hand knobs counterclockwise together and hold until L disappears. ### Why won't the zones on my AGA Elise switch on while the oven works? An L in the display means the top is locked. Unlock it with the two left-hand knobs and the zones respond again. ### Can the lock on my AGA Mercury be set while cooking? No. The guide says it can only be set when every zone is switched off. --- **[Read on the site: AGA Elise or Mercury induction range showing L](https://rangerepair.center/error-codes/aga-l/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
