Samsung Fridge Not Cooling? Check Demo Mode First

Last updated: October 2026

Here's a scenario that plays out in kitchens every week: a Samsung refrigerator, sometimes brand new, sometimes just moved, sometimes bought as a floor model. The lights come on. The display is bright and responsive. Everything looks alive — but nothing gets cold. Both compartments sit at room temperature, and the compressor never seems to kick in.

Before you call for service, check one thing: Cooling Off mode. That's Samsung's official name for what everyone else calls demo or showroom mode — the setting stores use so the display lights up without the fridge actually cooling. It gets switched on for the showroom floor and sometimes never gets switched off, or it gets triggered accidentally during a move or a power event. Samsung states outright that no service is required to fix it. The fix takes ten seconds and costs nothing.

How to tell it's Cooling Off mode

The signature is unmistakable once you know it: lights and display work, but there is no cooling at all — both compartments at room temperature, compressor silent. On the display, look for any of these: "O FF", "OF OF", "OFF OFF", or scrolling temperature bars that never settle on a real temperature. If you see one of those and the fridge isn't cooling, you're almost certainly looking at Cooling Off mode, not a broken refrigerator.

This is most common on newly purchased units, floor models, and fridges that were recently moved — any situation where the fridge spent time in a showroom or in transit with the mode engaged.

How Cooling Off mode gets turned on by accident

It helps to know how people end up here, because the mode is rarely turned on deliberately. The most common story is the floor model: it was displayed in Cooling Off mode at the store, and the mode was never exited after delivery. The second is the move — the button combination that exits the mode is also easy to trigger accidentally while wiping down the control panel or leaning against it during a move. Power events can do it too. The giveaway in every case is the same: everything looks alive, nothing gets cold, and the display shows one of the OFF indicators or scrolling bars. If that matches, run the exit steps above before you do anything else — it's the only refrigerator "repair" that takes ten seconds and requires no tools.

Samsung's official exit steps

These come straight from Samsung's US support pages (their answers ANS10006925, ANS10006926, and troubleshooter TSG10007315):

1. Press and hold the two top-left buttons of the control panel simultaneously for 5–8 seconds, until you hear a chime.
2. Wait a few moments and confirm the display does not return to Cooling Off mode. If it slips back — showing the OFF indicators or scrolling bars again — repeat the button hold.
3. On newer models, a top-right button may also be required — if the two-button hold doesn't work, check your user manual for your model's exact combination.
4. Family Hub models toggle Cooling Off through the Fridge Manager app instead of the panel buttons.
5. Allow several hours for cooling to return. This is the step people get wrong: the fridge doesn't snap to 37°F the moment the mode exits. Give it several hours before you decide it didn't work.

Samsung's own support documentation is worth bookmarking: ANS10006925 and ANS10006926 cover the mode and its indicators, and TSG10007315 is their step-by-step troubleshooter.

Samsung error codes, translated

If your Samsung is showing a code rather than the Cooling Off indicators, here's what Samsung's support pages say each one means. Codes are a starting point, not a full diagnosis — but they tell you which system to look at.

A note on the fan codes (21E, 22E/22C): the underlying checks are the same ones in our general guides — the evaporator fan check (unplugged, panel off, spin the blade by hand) and the defrost system diagnosis. The code just tells you which fan the board is unhappy with.

What if it's not demo mode and not a code?

Then your Samsung is an ordinary fridge with an ordinary problem, and the standard diagnostic tree applies: listen for the evaporator fan, look for frost on the back freezer wall, feel for airflow at the fridge vents. Work through Fridge Not Cooling but Freezer Works: What's Wrong in order — the checks are brand-agnostic and each one is free.

One Samsung-adjacent warning that belongs here: if your fridge is an LG, not a Samsung, and it's warm while the compressor seems to run normally, check the manufacture date. LG refrigerators with linear compressors built between 2014 and 2017 had a documented failure wave (a 2020 class-action settlement, whose claim window is now closed). LG compressors typically carry a 10-year sealed-system warranty, so check warranty status before paying out of pocket — and sealed-system work is always a certified-technician job, never DIY.

While you wait for it to cool: food safety

Remember that a fridge in Cooling Off mode has been at room temperature the whole time it was engaged. The FDA's rule: discard refrigerated perishable food (meat, poultry, seafood, milk, eggs, leftovers) that's been above 40°F for 4 hours or more — and don't trust the sniff test, because the bacteria that make you sick don't always make food smell bad.
