You walk into the kitchen on a July morning in Orlando, the milk feels warm, and your Samsung is sitting there showing OF OF on the display instead of the temperature. Or it is a different scene: the fridge is still cold, but the panel is flashing 22E or 5E and beeping at you. Either way, your Samsung is trying to tell you something with a short code, and the code is the fastest way to figure out what is wrong before anybody pays for a service call.
Some of these codes are a five-second fix you can do standing at the door. Others point at ice buildup or a failed sensor that needs a tech. Below is a table of the codes we see most around Central Florida, then a closer look at the few that matter most. The OF OF one in particular fools a lot of people, so start there if your fridge quietly stopped cooling.
Samsung refrigerator error codes at a glance
Here are the codes Samsung refrigerators show most often. Newer panels use a C on the end where older ones used an E (22C versus 22E), but they mean the same thing. If your exact code is not on this list, treat it as a sensor or fan fault and get it diagnosed rather than guessing.
| Code | What it means | Likely cause | What to do |
|---|---|---|---|
| OF OF (also O FF or OF F) | Cooling Off, demo or showroom mode. Not a fault. The fridge stopped cooling on purpose. | The cooling-off mode got switched on by accident, often by kids or while cleaning the panel. | Exit cooling-off mode by pressing and holding two buttons for several seconds. Combo varies by model. |
| 22E or 22C | Refrigerator (evaporator) fan error. | Usually ice buildup around the fan from a defrost or seal problem. | Let it defrost, then test. If it comes back, call a tech. |
| 21E or 21C | Freezer fan error. | Ice buildup around the freezer fan or a failing fan motor. | Defrost and retest. A repeat means a tech. |
| 5E or 5C | Fridge defrost sensor issue. | A defrost sensor that has failed or lost connection. | Get it diagnosed. This is a sensor and wiring job. |
| 8E or 8C | Ice maker sensor issue. | A failed ice maker sensor or a wiring fault. | Diagnostic needed. Ties into Samsung ice maker problems. |
| 1E or 2E | A temperature sensor fault. | A failed thermistor or a loose sensor connection. | Get it diagnosed. The sensor is the usual replacement. |
| 39E or 39C | Ice maker function error. | The known Samsung ice maker fault, often frost related. | Defrost the ice maker. Recurring faults need a tech. |
The big split here is simple. OF OF is a setting, not a breakdown. Everything else is the fridge reporting a part or a sensor that is not behaving, and most of those start with ice and end with a diagnostic.
Of of and cooling-off mode, the easy one
This is the call we get most, and it is the one you can fix yourself in under a minute. OF OF (you may see it as O FF or OF F depending on the panel) is not an error at all. It is Cooling Off mode, also called demo or showroom mode. Stores use it so a fridge on the sales floor lights up and runs the display without actually cooling and running up the power bill. The fridge stops cooling on purpose.
The problem is that this mode is easy to trigger by accident at home. A kid leans on the panel, somebody wipes the buttons down while cleaning, and the fridge quietly switches to showroom mode. Hours later the food is warm and the only clue is OF OF on the screen. Nothing is broken. The fridge just thinks it is sitting in a showroom.
To get out of it, you press and hold two buttons at the same time for several seconds until the display beeps and the temperature comes back. The exact combo depends on your model. On a lot of Samsung units it is Power Freeze and Power Cool held together, and on others it is Energy Saver and Lighting, or Fridge and a second button. Hold for about eight seconds and watch for the panel to switch from OF OF back to a normal temperature reading. Your owner's manual lists the exact pair for your model. Once it is cooling again, give it a few hours to pull back down to temperature before you judge whether the food is still good.
The fan-error codes 22e and 21e, usually ice
The 22E and 21E codes (22C and 21C on newer panels) are fan errors. 22E is the refrigerator side evaporator fan, and 21E is the freezer fan. The control board expects the fan to spin, and when it cannot, it throws the code. In Florida the cause is almost always the same thing: ice.
Here is how it happens. The fan lives near the evaporator coil behind a panel inside the fridge or freezer. When the defrost system falls behind or a door seal lets in our humid Orlando air, frost builds up on the coil and creeps over to the fan blade. Once enough ice forms, the blade hits it, the fan stalls, and you get 22E or 21E. You can sometimes hear it before the code shows, a rattle or a clicking as the blade taps the ice.
A full defrost will often clear the code for now. Empty the fridge or freezer, unplug it, and leave the doors open with towels down for several hours so the ice melts off the fan and coil. Plug it back in and see if the code stays gone. The honest part is that on most fan-error calls the frost comes right back, because the reason the ice formed in the first place is still there. That points at a defrost heater, a defrost sensor, a bad door gasket, or a failing fan motor, and those need a tech with the right parts. Do not chip at the ice around the fan with anything sharp. The blade and the coil tubing damage easily, and a punctured line turns a frost problem into a much bigger one.
How to reset a Samsung refrigerator
A reset clears the kind of one-off glitch that leaves a code stuck on the panel after the real problem is already gone. It will not fix a frozen fan or a dead sensor, but it is worth a try before you assume the worst, and it is the first thing we do on a lot of calls.
The most reliable reset is a power cycle. Unplug the refrigerator from the wall, or flip its breaker off, and leave it off for five minutes. That drains the control board and lets it boot fresh. Plug it back in and watch the display. If the code was a fluke, it clears and stays clear. If it comes right back, the fault is real and the code is pointing you at the part that needs attention.
Some Samsung models also have a panel reset where you hold a couple of buttons, and the cooling-off exit for OF OF is its own version of that. But the breaker reset works on every model and does not depend on remembering a button combo. One thing to know: after a power cycle the fridge takes a few hours to come back to full temperature, so do not panic if it reads warm right after you plug it in.
What a Samsung refrigerator repair costs in Orlando
If your code turns out to be OF OF, your cost is zero. You exit cooling-off mode and you are done. If it is a fan, a sensor, or a defrost part, that is a parts-and-labor job, and the price depends on which part.
For real numbers, Yale Appliance's 2025 service data puts the average refrigeration repair at about $255, with most jobs landing in the $150 to $900 range depending on the part. A sensor or a fan motor sits toward the lower-to-middle end of that. A sealed-system or compressor problem is what pushes a job toward the top of the range.
Here is how we handle it at QLAMA. The diagnostic is $90, and we waive it if you go ahead with the repair. We quote a flat price on-site before we touch anything, so there is no hourly meter and no invoice that keeps climbing. If the fix is not worth it on an older fridge, you owe the $90 and we leave. For comparison, a new Samsung French-door refrigerator runs about $1,200 to $2,500, so on a fridge that is otherwise sound, clearing a sensor or fan code is almost always the cheaper road.
When to call an Orlando tech
Call when a fan code like 22E or 21E comes back within a few days of a full defrost, because that means the frost is returning and the underlying defrost or seal problem is still there. Call when you see a sensor code such as 5E, 8E, 1E, or 2E, since those point at a failed sensor or wiring that needs a meter and the right part. Call when the fridge will not hold temperature even with no code showing, or when you hear grinding or clicking from inside. Those mean parts and tools most homeowners do not keep on hand, and guessing at a sealed system is not worth the risk. The one code you can almost always handle solo is OF OF, so try that exit first before you book anything.
QLAMA Appliance Repair services refrigerators across Orlando, Winter Park, Kissimmee, Sanford, Dr. Phillips, Windermere, Oviedo, Lake Nona, Winter Garden, and the surrounding communities within roughly a 30-mile radius of Orlando, residential and commercial.
Common questions about Samsung refrigerator error codes
My Samsung fridge stopped cooling and shows OF OF. Is it broken?
No. OF OF is Cooling Off mode, also called demo or showroom mode, and it stops cooling on purpose. It usually gets switched on by accident. Press and hold two buttons together for about eight seconds, often Power Freeze and Power Cool or Energy Saver and Lighting depending on the model, until the display shows a temperature again.
What does the 22E code mean on a Samsung refrigerator?
22E (or 22C on newer panels) is a refrigerator fan error. The evaporator fan cannot spin, and in Florida that is almost always ice buildup around the blade. A full defrost often clears it, but if it comes back the defrost system, a door seal, or the fan motor needs a tech.
How do I reset my Samsung refrigerator?
Unplug it or flip its breaker off, wait five minutes, then power it back on. That drains the control board and clears one-off glitches. If the code returns right away, the fault is real and needs to be diagnosed. Give the fridge a few hours to return to temperature after the reset.
Are these codes the same with a C instead of an E, like 22C versus 22E?
Yes. Samsung moved from an E suffix on older models to a C on newer ones for the same conditions. 22E and 22C are the same fan error, 21E and 21C are the same freezer fan error, and so on. The troubleshooting does not change.
Can I keep using my Samsung fridge with an error code showing?
It depends on the code. OF OF means it is not cooling, so the food is at risk until you exit that mode. A fan or sensor code may let the fridge keep running but cool unevenly, which is hard on the food and the compressor. Clear what you can yourself, and if the code sticks, get it looked at before parts fail further.
A code that comes back after a defrost and a reset is the fridge telling you a part or sensor needs a closer look, and that is what we sort out every week across Orlando. We will tell you the flat price before we start.
