Kenmore Refrigerator Error Code Er 6

Er 6 indicates an abnormal room temperature sensor condition, specifically a cut wire or short circuit in the sensor circuit. It is a secondary error code that appears during the refrigerator's display check mode rather than as a primary operational fault. The control board cannot correctly read the ambient room temperature when this fault is active. The first diagnostic step is inspecting the CON5 connector for a loose or faulty connection.

Er 6 is a secondary error that appears in display check mode and is related to the room temperature sensor rather than the core refrigeration circuit. In many cases the refrigerator will continue cooling while this fault is present, but the control system may not be able to optimize performance based on the surrounding environment. It is best to address the fault promptly to avoid any related control issues. If food temperatures appear inconsistent, stop using the appliance and schedule a repair.

If the fix is simply reseating the CON5 connector, there may be no parts cost at all, only the time to access and inspect the connection. Replacing a room temperature sensor typically costs between $15 and $60 for the part, depending on the specific model. If a section of wiring harness needs replacement, parts and labor can range from $80 to $200 or more at a service center. Control board replacement, if needed, is the most expensive outcome and can range from $150 to $400 or higher.

Start by locating and firmly reseating the CON5 connector in the wiring harness, as a loose connection is the most common cause. If the error persists, inspect the full length of the room temperature sensor wiring for any cuts, pinches, or corrosion. Use a multimeter to test continuity in the wiring and resistance at the sensor terminals to determine whether the sensor element itself needs replacement. If all wiring and the sensor test correctly, the control board may need professional evaluation.

A power reset may temporarily clear the Er 6 code from the display, but it will return if the underlying wiring or sensor fault is still present. The code reflects an actual electrical fault in the sensor circuit, so resetting the unit does not repair the problem. A proper fix requires diagnosing and correcting the issue at the CON5 connector, wiring harness, or sensor itself. After the repair is made, the code should clear and not return.
