GE Refrigerator Error Code 0006

Error code 0006 on a GE refrigerator indicates that the control board has detected a reading from the freezer (FF) evaporator thermistor that falls outside the acceptable resistance range. The evaporator thermistor is a temperature sensor mounted near or on the evaporator coil in the freezer section. The control board continuously monitors the resistance output of this sensor to determine evaporator coil temperature and regulate defrost cycles and fan operation. When the resistance value is too high or too low to be a valid temperature reading, the board flags code 0006.

For homeowners, the evaporator thermistor is a small sensor clipped to the freezer's evaporator coil, which is the set of cooling coils usually hidden behind a back panel inside the freezer. This sensor tells the refrigerator's brain how cold the coil is. When it stops sending a believable signal, the refrigerator cannot properly manage defrost cycles or cooling, which can eventually lead to ice buildup or inconsistent temperatures in the freezer and fresh food sections.

This code is triggered by an open circuit in the thermistor or its wiring, a short circuit, physical damage to the sensor, or a connector that has corroded or pulled loose. In some cases, ice buildup around the sensor can cause erratic readings. Actual thermistor failure is the most common root cause.
