Book a visit

Three short steps, about a minute.

or call (844) 407-1890

Before you book,
in this order.

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

01

Press and hold CLEAR/OFF for 3 seconds to turn Control Lock off.

02

Set your cooking mode again.

Cleared?

The oven came through without a new part. If the same message returns during a later bake, or the oven stops heating partway through, book it as a fresh problem.

What not to do

Loc is a setting, not a stuck key; nothing needs repairing.

What you may
notice with it.

The oven problems Loc tends to arrive with. Answer these at the oven before anyone is booked.

All problems

No repair indicated

Nothing to repair.

A setting someone switched on, or a state the oven entered on purpose — a control lock, a Sabbath setting, a showroom mode that lights the display without heating. No part has broken and nothing has to be replaced.

In LG's own words

The oven is locked because of the Control Lock feature.

Questions
about Loc.

Can I clear Loc myself?
Press and hold CLEAR/OFF for 3 seconds to turn Control Lock off.
How do I remove Loc from my LG wall oven display?
Hold CLEAR/OFF for 3 seconds. The same press turns Control Lock on and off.
Why will my LG oven not start self-clean while Loc is showing?
Control Lock blocks self-clean from being set. Turn the lock off first, then choose the cleaning cycle.

Still showing Loc?

Book with the code exactly as shown, the full model number, and whether you can smell gas or burning — with a code, that is where the diagnosis starts.
