I HAVE A SAMSUNG FAMILY HUB REFRIGERATOR. I HAD THE POWER TO THE HOUSE GO OUT AND COME BACK ON DURING THE NIGHT. I ALSO HAVE ON OCASSION FAMILY MEMBERS NOT CLOSING THE LOWER FREEZER DOOR ALL THE WAY AT TIMES. I HAD A MESSAGE ON THE FAMILY HUB SCREEN SAYING ABNORMAL TEMP AND TO HOLD THE OK BUTTON FOR 3 SECONDS. THE NEXT DAY THE FRIDGE WAS NOT WORKING AND FULLY DEFROSTED.
I GOT A CODE 72 : ERROR ABNORMAL FRIDGE
I HAD A LOCAL SERVICE TECH COME OUT AND ADVISED THAT I NEEDED THE FRIDGE UNPLUGGED FOR 24 HOURS AND THEN SHOULD WORK FINE. SAIED THE COMPRESSOR IS FINE.
I UNPLUGGED FOR 24 HOURS AND IT DOES NOT WORK.
I CLEARED THE CODES AND THE SELF DIAGNOSTICS DOES NOT REPORT ANY CODES. ALSO THE RED LIGHT ON THE PCB BOARD IS A SOLID RED. NO BLINKING. I TRIED ALL THE DIFFERENT WAYS OF TRYING TO RESET THE REFRIG BUT NOTHING WORKED.
IT SEEMS LIKE SOMETHING IS WRONG WHERE THE FRIDGE DOES NOT KICK ON THE COMPRESSOR OR THE FANS INSIDE THE FRIDGE. THE FAN NEXT THE COMPRESSOR IS SPINNING. I VACCUMED THE CONDENSOR AND IT IS CLEAR OF ANY DIRT AND DUST.
WOULD IT BE WORTH WHILE TO REPLACE THE PCB BOARD? MAYBE A NEW BOARD WOULD POWER UP THE COMPLRESSOR AND FAN, ETC.?
ANY SUGGESTIONS WOULD BE MUCH APPREICATE. THANKS FOR YOUR HELP.
Hi. I have attached the service manual for this refrigerator. I would run the diagnostics in this manual if you have not already done so. See if there are any other errors codes. Also , the inverter board has a red LED on it that will indicate errors as well. You can check for proper voltage from the main board to the inverter. If voltage is correct you could have a bad inverter board. With what you have described, it does sound like the main board is faulty.
In the videos on this web site there is a video called repacking compressor starter. I think the correct term is compressor overload protector. I ordered the part and will give it a try. I’m surprised that there are no errors codes to lead me in the right direction.
Hi Brian. I finally got the compressor overload protector part # DA34-00004D. It did not solve the issue. Previously replaced the Main Board and Inverter Board. There are NO CODES posting. Would the next part to replace be the compressor? When you buy a new compressor does it come with the service port or do you need to purchase separately? What other parts do I need to order? What tools do I need? Can kind of Torch and Flux, Soder, etc do I need?
Yes, sounds like the compressor is faulty at this point. As long as you have power to the inverter then the compressor must be faulty. You would need a process tube. The compressor usually does not come with one. You will need refrigerant gages, R-134A refrigerant, torches, brazing rods , Flux, a vacuum pump, etc. You could use a oxygen/ acetylene torches with brazing rods or a butane torches with silver solder and flux. I wouldn’t recommend this repair without having training and experience in sealed system repairs.
Hi Brian. I’m still doing some trouble shooting. I did a oms test on the compressor terminals. I got a reading of 7 on all the different ways of connecting the probes. Is the compressor still good at these numbers or should it be higher? What is the spec of a good compressor? Also Message on the Family Hub Screen says “Temperature in the freezer is abnormally high. Please check if door is opened or hot foods are in the freezer. If the problem has been solved the message will disappear. If the warning continues, please call a Samsung Service Center. The refrigerator is not cooling and warm in side as nothing is happening. Could there be some kind of sensor done bad that shut done the unit? Maybe a Thermostat Sensor? Let me know your thoughts? Jeff
The ohms of the compressor test good at 7 ohms. The compressor could still be faulty with proper ohm readings. I do not think a sensor would cause this issue, but it is possible. It should also be giving an error code for the sensor failure. I would try and run the compressor test in the service manual if not done so already. Page 101 for forced compressor run. Also there is a flow chart to follow for a compressor not running. Page 111 has trouble shooting for compressor not running. Page 112 for inverter board errors
