Electrolux codesElectrolux range codes

Configuration mismatch between the ESEC-UIB and the Induction Housing Assembly.

First step from the service manual

Disconnect power, wait 30 seconds and reapply power. If fault returns, activate simultaneously both right front and right rear On/Off keys for 5 seconds until error code is replaced by '8.8'.

What 39 means on a Electrolux range

Error code 39 on an Electrolux induction range indicates a configuration mismatch between the ESEC-UIB (Electronic Surface Element Control User Interface Board) and the Induction Housing Assembly. These two components must share matching firmware or configuration data to operate together correctly. When the control system detects that these components are not communicating with compatible configuration parameters, it flags error 39 to prevent unsafe or unpredictable induction cooking operation.

This type of mismatch typically occurs after a component replacement where a new ESEC-UIB or Induction Housing Assembly is installed without being properly paired or matched to the existing unit. It can also occur after a power surge or interruption that corrupts stored configuration data in one of the two components. In some cases, the error appears due to intermittent communication failures on the control bus connecting the two boards.

The diagnostic process begins with a full power reset: disconnect power at the breaker, wait 30 seconds, then restore power. If the fault returns, the technician should simultaneously press both the right front and right rear On/Off keys and hold them for 5 seconds until the display changes to '8.8'. This key sequence initiates a configuration or re-pairing routine between the ESEC-UIB and the Induction Housing Assembly. If the error persists after this procedure, one or both components likely require replacement.

Common causes of 39

  1. 01

    Replacement component mismatch

    Wiring / connection

    If either the ESEC-UIB or the Induction Housing Assembly was recently replaced, the new part may not be configured to match the existing unit. This is the most common trigger for error 39 after a prior repair.

  2. 02

    Corrupted configuration data from power event

    Wiring / connection

    A power surge, outage, or unstable voltage can corrupt the stored configuration data in one of the two control components, causing them to fall out of sync. Performing the key sequence reset procedure may restore proper configuration.

  3. 03

    Intermittent communication fault on control bus

    Wiring / connection

    Loose or damaged wiring connections between the ESEC-UIB and the Induction Housing Assembly can cause unreliable data exchange, triggering the configuration mismatch error. Inspect connectors for corrosion, looseness, or damaged pins.

  4. 04

    Failed ESEC-UIB

    Part replacement

    If the user interface board has failed internally, it may be unable to correctly read or transmit configuration data to the Induction Housing Assembly, producing error 39 persistently even after reset attempts.

  5. 05

    Failed Induction Housing Assembly

    Part replacement

    A fault within the Induction Housing Assembly itself can prevent it from recognizing or accepting configuration data from the ESEC-UIB. If the reset procedure and wiring inspection do not resolve the error, the housing assembly may need replacement.

Frequently asked questions about 39

What does 39 mean on a Electrolux range?
Error code 39 means the range has detected a configuration mismatch between the ESEC-UIB (the surface element control and user interface board) and the Induction Housing Assembly. These two components must be properly matched and communicating for the induction cooktop to operate safely. The range locks out cooking functions until the mismatch is resolved.
Will resetting the range clear error code 39?
A basic power reset may clear error 39 if it was caused by a temporary glitch. Disconnect power at the breaker, wait 30 seconds, and restore power. If the code returns, you must simultaneously press and hold both the right front and right rear On/Off keys for 5 seconds until the display shows '8.8', which initiates a re-pairing routine between the two control components.
Is it safe to use my Electrolux induction range while error 39 is active?
You should not attempt to bypass or ignore error 39. The range flags this code specifically to prevent unsafe operation when its control components are out of sync. Continuing to use the cooktop in this state could result in unpredictable induction behavior. Resolve the fault before resuming normal cooking.
How much does it cost to fix error code 39 on an Electrolux range?
If the error clears with the built-in reset key sequence, there is no parts cost. If a component requires replacement, an ESEC-UIB or Induction Housing Assembly typically costs between $150 and $400 or more for parts, depending on the specific model. Adding professional labor, total repair costs can range from $200 to $600 or higher.
Can I fix error code 39 myself, or do I need a technician?
The initial reset steps, including the power cycle and the right front plus right rear On/Off key sequence, are safe for a homeowner to attempt. However, if those steps do not resolve the error, diagnosing and replacing the ESEC-UIB or Induction Housing Assembly requires familiarity with appliance wiring and control board handling. A qualified appliance technician is recommended for component-level repairs on induction ranges.
