Electrolux Refrigerator Error Code t3

The t3 code indicates that the ice maker's TH3 suction line temperature sensor has been detected as open or shorted by the control board. You will see "Ice" on the freezer display and "t3" on the fresh food display simultaneously. The error means the refrigerator cannot get a valid temperature reading from that sensor, so the ice maker is disabled. Diagnosis should follow the Ice t3 flow chart to pinpoint whether the sensor, wiring, or control board is at fault.

The t3 error affects only the ice maker system and does not directly impact the refrigerator's ability to cool food. Your freezer and fresh food compartments should continue operating normally while this fault is present. It is not an immediate safety hazard, but the ice maker will remain non-functional until the fault is resolved.

A power reset may temporarily clear the error code display, but if the underlying fault in the TH3 sensor circuit still exists, the t3 code will return once the control board runs its diagnostic check. Resetting without repairing the sensor or wiring does not fix the problem. A permanent resolution requires identifying and correcting the open or shorted condition in the sensor circuit.

A knowledgeable DIYer can perform basic steps such as inspecting connectors, reseating wiring harness plugs, and checking for visible wire damage. However, properly testing the TH3 sensor's resistance and tracing the wiring harness through the freezer compartment requires a multimeter and comfort working around refrigerant lines. If the sensor or control board needs replacement, some experience with appliance repair is recommended to ensure proper reassembly and avoid damaging components.

Repair costs vary depending on the root cause. If only a loose connector is the issue, there may be no parts cost at all. A replacement TH3 sensor typically runs in the range of $20 to $60 for the part alone. If a control board replacement is required, parts can range from $100 to $300 or more, with additional labor costs if a technician is hired.
