Defrost terminator or defrost heater?
My domestic refrigerator /freezer coil started freezing up. I defrosted with the hair dryer and that lasted a week.
The heater is not open. Don't they usually fail open? I jumpered the terminator to wait and see what happens. The defrost timer seems to be working, at least it is advancing.
this unit is really in a difficult place to move, second floor and small steep staircase so i really don't want to replace it.
What do you think is the most likely problem?
