I would like to know how to set a GE refrigerator Profile line to manual defrost mode. The evaporator assembly in my freezer freezes up and becomes and ice block, the freezer continues to work but the refrigerator compartment warms up. I removed the evaporator fan cover and de-frosted the evaporator assembly and it began to work well i put back the evaporator cover and the same thing happened about a week later. This time I de-frosted the evaporator assembly and decided to run the refrig without the evaporator cover to monitor what is going on the freezer iced up again and the freezer and the refrigerator compartment both ran warmer than normal, the unit displays a number for the temperature for the freezer and the refrigerator compartment and these numbers are higher then normal. The defrost heater may need to be replaced but I just want to make sure before I replace it.
ANSWER Hello Al,
As per the manufacturer, the only way to force a defrost on these units is to actually jump voltage from a hot circuit to the defrost circuit at the main control board. I always just get the wiring diagram out and unplug the unit and test the circuit for resistance from the main board. There are only four components of the defrost circuit in these units. Not counting the wiring harness as a part, the defrost heater, the defrost thermostat, the defrost control, (main electronic control board), and the temperature sensors. If the defrost heater and thermostat check out good, I would at that time change the evaporator sensor. If that doesn't do it, time to change the board.
