Book a visit

Three short steps, about a minute.

or call (844) 252-4077

Before you book,
in this order.

Each step comes from Samsung's own guidance for L on its cooktops. Follow it to the end: the last card says whether this is a visit.

01

Turn the lock off with the lock key as the manual shows.

02

Check that L has gone out and the keys respond before you start cooking.

03

If L comes back without anyone touching the lock key, book a visit.

Cleared?

The cooktop came right without a new part. If the same message returns while a zone or burner is on, or the top shuts itself down again mid-meal, treat it as a fresh problem and book it.

What not to do

L is not a stuck key or a board problem. The cooktop is working; it is simply refusing changes until the lock is released.

What you may
notice with it.

The cooktop problems L tends to arrive with. Answer these at the cooktop before anyone is booked.

All problems

No repair indicated

Nothing to repair.

A state the cooktop was put in, or one it picked deliberately — a child lock, a demo mode that lights the keys but heats nothing, a residual-heat letter over a zone that is still warm, a prompt that no pan has been found. Nothing has broken and no part is called for.

In Samsung's own words

The child lock is activated.

Questions
about L.

Can I clear L myself?
Turn the lock off with the lock key as the manual shows.
How do I unlock a Samsung cooktop showing L?
Hold the child lock key as described in your manual.
Can L turn on by accident?
Yes, if the lock key is held while wiping the panel.
Why does my Samsung show L when I press the Power key?
L means the child lock is activated, so the keys do not change anything, including power. Samsung's information code table lists L for this reason alone. Release the lock and the Power key works again.

Back to your everyday

Still showing L?

Book with the code copied exactly, the full model number, and whether there is any smell of gas or burning — with a code in hand, that is where the diagnosis starts.
