Question about Samsung Refrigerators
The front display is reading OF instead of the freezer/fridge temps. Both the fridge and freezer are coming to room temperature. We looked through the manual with no luck and even searched the internet. We unplugged the unit for 10 mins and plugged it back in hoping that it would reset itself but still see the "OF" on display.

Ok, what I found out is that there are codes built into the front panel. If you hold the top left and right buttons for 5 seconds, the fridge will reset. If there are no issues, the panel goes blank. If there is a dash in the right side of the panel, there is an issue with the fridge side. In the left, freezer side. The dash indicates a defrost problem. Only a couple of things can cause this. 1. Sensor 2. Heater 3. Fan, 4. control board.

I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........
In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.
Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.
Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)
Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.

I was having the same problem but with the refrigerator side. I know your problem was with the freezer side but I hope this works in your situation too. I was also told to unplug the fridge for 20 minutes and that did not do a thing to reset the circuit board in my situation. Unplug the refrigerator first. In the back of the refrigerator at the bottom is a metal panel. Remove that panel and off to the right side of it should be a white looking plastic box. Unscrew that box from the fridge and open it up to get to the circuit board. Remove ALL harnesses from the circuit board and capacitor. After doing so plug them all back in and reassemble everything back together and plug in the fridge. This should reset the board and allow it to function correctly. This is advice I got from someone else and everything as of today is cooling down like it should. I hope this helps everyone else out. Best of luck.
Also since the evaporator was frozen solid at the bottom on the refrigerator side I had to leave the power off until it thawed and then had to soak up all the water that collected at the bottom of it.

Good call Cooltech! My new LG "open box" deal from Best Buy must have been delivered once before. I hauled it home, plugged it in and Er CO was on the display. The doors must have been removed to get through tight spaces, exposing the bundle of wires and connectors under the left hinge cover. One wire had been repaired with a crimp lug, wire cut too short, and the crimp was no good. I soldered the connection and added 2" of wire so it wouldn't be stressed. Works!

If your control panel displays "OF" instead of the temperature, your refrigerator is in "Cooling Off" mode. In Cooling Off mode, the refrigerator appears to be running normally, but the compressor is off so the unit does not cool. Cooling Off mode is used by retailers to save electricity when the refrigerator is on the showroom floor.
Note: Cooling Off mode is also called Demo mode or Exhibition mode.
Depending on your refrigerator, to remove your refrigerator from Cooling Off mode:
The temperature display re-appears after the unit is out of Cooling Off mode.
