Electrolux Refrigerator Error Code dA

The dA code indicates that the freezer air temperature sensor (an NTC thermistor) is sending a signal outside the acceptable range to the control board. This means the refrigerator cannot reliably monitor freezer temperature. The fault may point to a defective sensor, a wiring issue, or a connector problem in the sensor circuit.

A dA fault means the freezer is operating without reliable temperature feedback, which can lead to inadequate freezing or uncontrolled compressor operation. Food stored in the freezer may not be held at safe temperatures. It is best to address this error promptly and avoid relying on the freezer for food that requires strict temperature control until the issue is resolved.

A reset may temporarily clear the dA code from the display, but the error will return if the underlying sensor fault is still present. Because the code is triggered by an out-of-range electrical signal from the sensor, the control board will detect the problem again once it resumes monitoring. A reset is not a fix and should only be used as part of the diagnostic process.

Some aspects of this repair are accessible to a knowledgeable DIYer, such as inspecting and reseating the sensor connector or testing the sensor with a multimeter. However, an important limitation is that the sensor cable is foamed inside the cabinet walls and cannot be replaced, so if the fault lies in that embedded wiring, a professional technician will need to evaluate the available repair options. Replacing the sensor itself, if it is the failed component, is a more straightforward task.

If the repair involves replacing the NTC temperature sensor, parts typically range from around $20 to $60 depending on the model, with labor adding to the total if a technician is needed. If the issue is only a loose or corroded connector, the repair cost may be minimal. A control board replacement, if required, can range from $100 to $300 or more for parts alone.
