Three short steps, about a minute.

or call (844) 252-4077

Before you book,
in this order.

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

01

Make sure every knob is off; Monogram only lets the lockout change with all knobs off.

02

Press and hold Lock Control for three seconds until it beeps, then release within five seconds.

03

If LOCKED will not clear, 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

LOCKED is not a gas valve failure. It is a feature someone turned on.

What you may
notice with it.

The cooktop problems LOCKED 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 Monogram's own words

To lockout the flow of gas to the cooktop and to lock the control, press and hold the Lock Control pad for 3 seconds

Questions
about LOCKED.

Can I clear LOCKED myself?
Make sure every knob is off; Monogram only lets the lockout change with all knobs off.
Why won't my Monogram gas cooktop unlock?
Monogram's lockout only changes when every knob is off; turning it with a knob on produces a chime instead. Turn all knobs off, then hold Lock Control for three seconds.
Does the Monogram lockout stop the gas or just the display?
It stops gas flow to the cooktop and locks the control, according to Monogram's manual.
Why does my Monogram ZGU36RSLSS chime instead of locking?
A burner knob is probably not at Off. Monogram only lets the gas lockout change with every knob turned off, so check each one and hold Lock Control for three seconds again.

Still showing LOCKED?

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.
