I have Samsung with a twin cooling system. The freezer works great but the refrigerator side frosts up where air from the fan will not blow cool air into the refrigerator from the evaporator. I have traced it down to the thermal fuse being open. The defrost on the refrigerator side doen't work. Any ideas as to why the thermal fuse would be blown and am I on the right track to fix the problem?
ANSWER Hello John,
The temperature sensor DA47-00095E on the evaporator may have had a short in it that caused it to go out. Replacing the sensor should take care of the problem of not defrosting.
