Bosch Refrigerator Error Code E06

E06 indicates that the refrigerator compartment evaporator temperature sensor is reporting a value outside the accepted range, specifically at or above 60°C or at or below -55°C. The control board treats these extremes as evidence of a sensor break, short circuit, or loss of contact rather than an actual temperature. The fault is electrical in nature and requires inspection of the sensor, its wiring, and connector points.

A power reset may temporarily clear the E06 code, but it will return if the underlying sensor fault is still present. Because the error is triggered by a continuous out-of-range reading from the sensor circuit, clearing it without repairing the root cause will not restore normal operation. A lasting fix requires addressing the sensor, wiring, or connector issue directly.

If the evaporator temperature sensor itself has failed, parts typically cost in the range of $20 to $60 depending on the specific model. If a professional technician is needed for diagnosis and replacement, total repair costs including labor generally range from $100 to $250. Wiring harness repairs or control board replacement, if required, can push costs higher.

Start by unplugging the refrigerator and locating the evaporator temperature sensor in the refrigerator compartment. Check all connector plugs for secure seating and inspect the wiring harness for visible damage or corrosion. Use a multimeter to test the sensor's resistance at a known temperature to determine if the thermistor has failed. If the sensor reads open or shorted, replacing it is the correct repair.

When E06 is active, the control board cannot receive valid temperature data from the evaporator sensor, which compromises the refrigerator's ability to regulate cooling accurately. Food safety may be at risk if the compartment is not maintaining proper temperatures. It is advisable to check the actual compartment temperature with a thermometer and address the fault promptly rather than continuing to operate the unit unmonitored.
