Kenmore Range Error Code 39

Error code 39 on a Kenmore range signals a configuration mismatch between the User Interface Board and one of the two Induction Housing Assemblies. The control system has detected that the UIB and the induction hardware are not properly matched. This is most often triggered when one of the induction housings has been replaced and the correct ESEC-UIB was not installed alongside it.

Start by performing a full power reset for at least 30 seconds. If the code persists, verify that the ESEC-UIB installed in the range is the correct version for the combination of induction housings currently in the unit. Also check that all wiring harness connections between the UIB and the induction housings are fully seated. If the wrong UIB is installed, replacing it with the correct version should resolve the fault.

Repair costs depend on the root cause. If only a wiring connection needs reseating, the cost may be limited to a service call fee, typically in the range of $75 to $150. If the ESEC-UIB needs to be replaced, parts and labor combined can range from $150 to $400 or more depending on your location and the specific part required. Getting a diagnosis from a qualified technician before ordering parts is advisable.

A power reset is always the recommended first step. Disconnect power to the range, wait at least 30 seconds, and restore power. If the fault was caused by a temporary communication glitch, the reset will clear it. If the code returns immediately, there is a genuine hardware or configuration mismatch that requires further diagnosis.

It is not recommended to continue using the range while this fault is active. The error indicates the control system cannot confirm a proper match between the user interface and the induction heating components. Operating the range in this condition could result in unpredictable behavior from the cooktop. Address the underlying cause before resuming normal use.
