Last night we found both the freezer and refrig sections at a higher then normal temp. At first I thought it might have just been coming out of defrost,but the refrig area seemed to be staying warmer then normal. I attempted to lower the temp setting and found that the control panel appeared to be inop. I could not change either the freezer or refrig temp settings nor turn on the "temp alarm" or set it to "max cold". This morning the tempertures in both areas are back to normal, but the panel is still not functioning. The unit is just over two years old. Thanks in advance for your help.
