The control board blew. You will need to replace the control board on your unit and everything will work correctly again. When a power surge happens it will blow the weakest link, and if your system is not on a protected outlet then the weakest link is your control board.

Our power went out due to the snow storm, and the display panel shows 88 on each side...how do I reset this...will this cause the fridge temp to go up?


From http://www.samsung.com/us/support/supportMain.do

Your refrigerator is equipped with an onboard diagnostic system. If the diagnostic system detects a fault, it will display a specific line segment on you refrigerators LED display. If your refrigerator is displaying an error code, please note the error code, and reset the refrigerator by unplugging the refrigerator for 30 seconds. When the refrigerator is plugged in, it performs a self diagnostic check of the various sensors and functions. If the error code reappears your refrigerator will require service. Please click the "Create Online Service Request" button below this article to initiate the service process. After a power outage the display panel may start blinking "88 88." If you unplug the unit for 30 seconds then plug it back in the display will return to normal operation after several hours. The power outage/surge can cause a communication error between the circuit boards in the unit. It can take several hours for these boards to stabilize.

If the display does not reset, go to the Samsung Support link above, enter your model number, and follow the prompts to request a service ticket.

Good luck, and if this helps, please rate my answer!

Power surge caused wine cooler to quit cooling


Power surges, spike and brown-outs are a nemesis to small refrigeration units. The capacitor for the compressor likey was affected and possibly the start components in general, especially if the unit was operating when the surge occured.

Panel showing 88 88


You can try unplugging , wait a few minutes , and plugging back in . If that doesn't work , then the main control board , located on the back of the refrig ( behind an 8 " X 10 " panel ) , was damaged by the power surge , and needs to be replaced .

Sounds like you should get estimates and turn in on homeowners insurance. Power surges are very destructive and you have lost the control board at least and maybe some switches. Eric

See if you accidentally unpluged or damaged any wires under the refer during the move. There are connectors that can sometimes easily pull apart if a dolly hits them.
