A:Answer I'm happy to help with this, CatL! Changing the temperature should be as easy as tapping the "Fridge" or "Freezer" button until the desired temperature is displayed. One thing to note is that once the temperature is set, the display will return to showing the current temperature until the set temperature is reached. Another reason you may be having difficulty is if the control lock is engaged. You can determine this by locating the lock icon just above the "Door Alarm" button. If this icon is lit up, the control panel is locked, and you will need to press and hold "Door Alarm" for about 3 seconds. You should hear a chime and the lock icon will turn off indicating the control panel is now unlocked. I am also providing this link (https://bit.ly/3vRt7t5) to the user manual for additional information on using all the great features this model has to offer. ^Jecca
