What C12
actually means.
Monogram's electronic cooktops have a custom settings menu that shows short codes. Under C1 for Control Lock, C11 is the standard lock you set by hand and C12 is Auto Lock, which locks the cooktop after it has sat in standby for 10 minutes. A cooktop that seems to lock itself is often set to C12.

What to do when C12 shows on the cooktopKind of codeMode, not a failure
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.
Usually leads toNo repair
Open the custom settings as the manual describes and move Control Lock from C12 to C11.
Shows up asCooktop Controls Unresponsive
Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element.

Before you book,
in this order.
Each step comes from Monogram's own guidance for C12 on its cooktops. Follow it to the end: the last card says whether this is a visit.
Open the custom settings as the manual describes and move Control Lock from C12 to C11.
To unlock right now, touch Control Lock for three seconds.
If the cooktop still locks on its own at C11, 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
C12 is not an error. It is a setting that locks the controls on purpose.
