Update. Whining evap motor.. I work in one of the largest retirement communities in the united states, (the villiages fl) and have for at least 25 years,so I am very familiar with ge appliances. (all their appliances are ge) I have in stock currently at least 30 mother boards. With the whining evap motor 99.5 percent of the time it is the board and not the motor. If the resistors below the j2 connector is burnt or discolored I will also replace the motor. Well in this case where the board would not even power the unit up, and I'm still scratching my head on this one. What I done was replace the evap motor and the sensor that is in the same harness (only because it's the old faulty design sensor).well it's been three days, and no call back. Hope I'm not bragging to early. My friend Paul a thirty five year ge appliance tech has taken upon himself to help me solve this problem. Once I find out I will gladly share this valuable information.
