How do I adjust the temperature settings on my Samsung sidebyside refrigerator?
Most have an up button and a down button. I assume by “decreases” you mean warmer. I think I recall seeing one board were they used only lights to indicate temperature and you could only turn it warmer which is a lower number to off then when you turn it on it starts at the coldest setting again. That is how you set it higher. But you need to find your manual. And anytime people have problems with electronic boards I recommend removing power to the unit to clear the board. That will reboot the computer and set it to the defaults if it is working.
