Electrolux Refrigerator Error Code E8

The E8 code indicates a shorted thermistor condition. The temperature sensor in the refrigerator is reporting readings above 90-95°F (32-35°C) for more than 20 minutes of compressor run time, which signals to the control board that the thermistor has failed with an internal short. The refrigerator flags this code to direct attention to the sensor circuit rather than assuming an actual temperature emergency.

The E8 code points to a faulty sensor rather than confirmed runaway temperatures, so the refrigerator may still be cooling adequately. However, with a shorted thermistor the control board cannot accurately regulate the compressor, which could eventually lead to temperature instability and food safety concerns. It is best to address the fault promptly and use a separate refrigerator thermometer to monitor actual interior temperatures in the meantime.

A power reset by unplugging the refrigerator for a few minutes may temporarily clear the E8 code from the display, but if the underlying thermistor or wiring fault still exists, the code will return once the compressor has run for more than 20 minutes with the sensor still reading out of range. A reset alone is not a repair. The thermistor circuit must be tested and any defective component replaced to permanently resolve the fault.

A knowledgeable DIYer with a multimeter can test the thermistor by disconnecting it and measuring its resistance, then comparing the reading to the expected value for the surrounding temperature. If the resistance reads near zero ohms or far below the normal range, the thermistor is shorted and needs to be replaced. The wiring and connector should also be inspected for damage or corrosion. If these checks pass and the fault persists, the main control board may need professional evaluation.

If the thermistor itself is the cause, parts typically range from around $15 to $60 depending on the specific model, and the repair is relatively straightforward. If a technician is needed for diagnosis and installation, total service costs including labor can range from roughly $100 to $250. A control board replacement, if required, would be more costly, generally ranging from $200 to $400 or more depending on the model.
