Verdict: Partly true. Unplugging a refrigerator for a few minutes does reset its controls, but Samsung says a reset is only worth doing in a few situations, and that in many cases you should request service instead because the reset erases the fridge's stored error history.
Where the idea comes from
Turning electronics off and on again fixes a lot of things, from routers to phones, and modern refrigerators have circuit boards and displays too. Unplugging a fridge also seems harmless. And sometimes it appears to work: the fridge starts cooling again, at least for a while.
What the evidence says
Samsung's support page on how to reset a Samsung refrigerator gives the method: unplug it, or turn off the circuit breaker, wait about five minutes, then restore power. But it limits when to do it. Samsung says it only recommends resetting or unplugging the fridge in three situations: when troubleshooting directs you to, when you're moving the fridge, or when you're cleaning it.
The page explains why. "Error code history and diagnostic information will be lost during a reset, since this data is stored in the fridge." It adds that any method you find to clear a code "is not going to be as helpful to you as proper troubleshooting and service," and that in many cases you should refrain from a reset and request service.
There's one situation where Samsung says a reset may be all that's needed: an 88 88 code, which can appear specifically after a power outage. It also points out that "OF OF" or "O FF" on the display means Cooling Off (Demo) mode, which doesn't need a reset at all and can be switched off separately.
There's a practical reason a reset can look like a fix. While the fridge is off, frost on the cooling coil can start to melt, so a fridge with a defrost problem may cool better for a day or two before the frost returns.
What to do instead
- Read the display first. Write down any code exactly as it appears, or take a photo.
- Check the manual or the maker's support site for that code before unplugging anything.
- Look for simple causes: a door not closing, a blocked vent, a control set too warm, or demo mode.
- If troubleshooting tells you to reset, unplug it or switch off the breaker for about five minutes.
- If the problem returns, stop resetting and book service, with the code and model number ready.
Exceptions worth knowing
- •After an outage, a reset can clear a power-related code on some Samsung models. If it comes back, it isn't an outage issue.
- •Brands differ. Other makers have their own reset steps and codes; check yours.
- •Food safety comes first. If the fridge has been warm, check it with a thermometer. See what the numbers on a fridge dial mean.
- •Repeated breaker trips are an electrical problem, not a reset problem. Leave the breaker off and call for service.

The short version: A reset is a troubleshooting step, not a repair, and it can erase the clues a technician needs.
