Repair Help

hello, Have a side by side refrigerator and the fresh food section is getting too cold. Freezer seems ok.

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.
