Trying to fix this Samsung RB1944SL refrigerator. Currently have to reset fridge every 6 hours to keep it working. Initially checked thermal fuses and defrost sensors and found freezer thermal fuse blown. Replaced both thermal fuses and defrost sensors per Samsung's service bulletin. Replaced original thermal fuses with bimetals per service bulletin. Did ohm tests on all sensors outside of fridge, and they seem to be fine, but problem continues. Tried new main board without success. Manual suggest checking voltage at the main board after a forced defrost. Put fridge into forced defrost, but not sure how to test voltage at the main board. Also found short in wire that runs down the fridge door to the front display.(What engineer thought running wires through a hinge would be a good idea?) Any way to get into the door to replace that wire bundle? Any help would be appreciated as this fridge is driving me to drink, and it will have to be warm beer.
