This fridge is very close to GX2SHBXVY05 which uses the Jazz board. But the Kenmore one uses a different board. This Kenmore 596.79323010 010 has more controls such as door alarm, water filter warning, etc. So the control board is different. In a Jazz board machine, if the diagnostic can defrost the evaporator which means the heater, defrost thermostat, the thermistors are good, I would definitely replace the Jazz board. Now this Kenmore one behaves the same, in diagnostic, defrost OK, thermistors are good, should I replace the board as well, just like the Jazz board? I never replace this board before. Please help!
