Answer Betty, the defrost heater DA47-00244U will need to be tested for resistance and it should measure 120O. If it does not measure 120O of resistance, then it would need to be replaced. From there, with the defrost sensor DA32-10104N at 50°F it should measure 8.87KO of resistance, at 32°F it should measure 13.29O, at 14°F should measure 20.42KO. Read More...
