- In writing the price, before anything is opened
What we can confirm
Signal OFF, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.
The signal
OFF
This is the one on the list that panics people and costs nothing. Demo or display mode is a setting for a shop floor: the lights work, the display works, the fans run, and the cooling is switched off entirely so a machine can stand in a showroom without running a compressor all day. A refrigerator delivered straight from a display, or one where a child has leaned on the right two buttons, will do exactly what a broken one does — and be perfectly healthy. It is always worth ruling out before anyone is called, and it takes about ten seconds.

What it narrows down to
Not an error — the machine has been told not to cool

What else belongs to the refrigerators
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
The fan over the condenser has stopped turning, and the machine has noticed
The fan that moves cold around the freezer is not turning
The fan feeding the fresh food side has stopped
The sensor reporting the freezer temperature is not making sense
The fresh food compartment's own sensor is not reporting properly
The sensor that decides when to melt the ice off the coil has failed
The machine cannot read the temperature of the room it is standing in
The fan that carries cold to the ice maker has stopped
The ice maker cannot tell whether the cubes are frozen yet
The ice maker's own motor is not turning the harvest
The internal water tank is missing or not seated
The main board and the display have stopped talking to each other

What the appliance is actually reporting
This is the one on the list that panics people and costs nothing. Demo or display mode is a setting for a shop floor: the lights work, the display works, the fans run, and the cooling is switched off entirely so a machine can stand in a showroom without running a compressor all day. A refrigerator delivered straight from a display, or one where a child has leaned on the right two buttons, will do exactly what a broken one does — and be perfectly healthy. It is always worth ruling out before anyone is called, and it takes about ten seconds.
The other light combinations that mean this
OFF · Demo mode · Display mode · OF OF · O FF
LG publishes what the indicator lights mean on the washers and dryers that have no numeric display. They are grouped here by what they mean rather than split into near-identical pages, and every pattern the maker names is printed above.
Where this appears, and why not to clear it
On the indicator lights, on a laundry machine with no numeric display. LG publishes what the patterns mean, and on those models the pattern is the entire diagnosis — it disappears the moment the power is cut. Write it down or photograph the panel before switching anything off, and count a full sequence rather than a single flash: the lights also blink to show cycle status, so treat it as an error only if the machine is misbehaving as well.
What to do about it
- Open the fresh food door. Hold the FRIDGE button and press Express FRZ three times.
- On some models it is the two buttons held together for three seconds instead.
- Listen for the chime that confirms the setting has changed.
- If the compressor starts and the cabinet begins to cool, that was the whole problem.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 419-0291 and describe what the panel is doing before booking anything.
