FREEZER WILL NOT GET COLD - REPLACED THE BLACK PART THEY CALL A RELAY OR A CAPASITOR - THEIR IS NOT MUCH TO A SELF DEFROSTING FREEZER. i WAS NOT SURE ABOUT THE 2 WIRE THAT ATTACH TO THIS PART ONE IS BLUE AND ONE IS WHITE. THIS PART HAS A LABEL OF "l" OR "N" I AM NOT SURE WHICH GOES TO WHICH. NEXT THING I TRIED IT BOTH WAYS AND THE FREEZER TURNED ON ONLY FOR ABOUT 10 SECOND THEN TURNED BACK OFF - DID I GET THE WRONG PART. IT WILL RUN FOR A COUPLE SECOND THEN SHUT OFF. ANY SUGGESTIONS??
