What LEDs 2,3 means on a Electrolux range

The LEDs 2,3 error code on an Electrolux range indicates an Incorrect Micro ID fault. This means the microprocessor within the electronic control board has reported an identification value that does not match what the system expects. The control board contains a main microprocessor that communicates its identity to the overall control logic during startup and operation. When that ID does not match the expected value, the system flags this fault to prevent incorrect operation that could result from running firmware or hardware mismatches.

This type of fault is almost always rooted in the electronic control board itself, either due to internal component failure, corrupted firmware, or a hardware defect within the microprocessor circuitry. It can also occur if a replacement board was installed that is not the correct part for the specific range model, resulting in a mismatch between the board's programmed microprocessor ID and what the appliance expects. Because the fault points directly to the identity of the microprocessor, external wiring issues or sensor failures are rarely the root cause. The diagnostic and repair path for this code leads directly to replacing the electronic control board, as the microprocessor is integrated into that assembly and is not serviceable separately.

Common causes of LEDs 2,3

  1. 01

    Failed Electronic Control Board

    Part replacement

    The microprocessor on the control board has failed internally, causing it to report an incorrect ID during self-check. This is the most common cause and the primary diagnostic target for this fault code.

  2. 02

    Incorrect Replacement Board Installed

    Part replacement

    If a control board was recently replaced, the installed board may not be the correct part for the specific model, causing a microprocessor ID mismatch. Verify that the board part number matches the range's model requirements.

  3. 03

    Corrupted Microprocessor Firmware

    Part replacement

    Internal firmware corruption within the microprocessor can cause it to report an invalid ID. This type of failure is not recoverable through a reset and requires board replacement.

  4. 04

    Power Surge or Electrical Event

    Part replacement

    A sudden power surge or voltage spike can damage microprocessor components on the control board, leading to an ID fault. Inspect for signs of burn marks or damaged components on the board.

Frequently asked questions about LEDs 2,3

What does LEDs 2,3 mean on a Electrolux range?
The LEDs 2,3 code on an Electrolux range indicates an Incorrect Micro ID fault. This means the microprocessor on the electronic control board is reporting an identification value that does not match what the system expects. It points directly to a failure within the control board itself. Resolving this fault requires replacing the electronic control board.
Can I fix the LEDs 2,3 error on my Electrolux range myself?
The repair for this fault code involves replacing the electronic control board, which is a task many experienced DIYers can perform. You will need to disconnect power to the range, access the control board, and swap the assembly with the correct replacement part. If you are not comfortable working with appliance electronics, hiring a qualified technician is recommended.
Will resetting my Electrolux range clear the LEDs 2,3 error?
Resetting the range by cutting power at the breaker or unplugging it is unlikely to permanently clear the LEDs 2,3 fault. Because this code indicates a microprocessor ID mismatch rooted in the control board hardware or firmware, the underlying cause will not be resolved by a reset. The fault will typically return after power is restored.
Is it safe to use my Electrolux range when the LEDs 2,3 error is showing?
It is generally not advisable to continue using the range when this fault is active. An incorrect microprocessor ID means the control board may not be operating as intended, which could affect how the range responds to commands or manages heating functions. Discontinuing use until the control board is replaced is the safest course of action.
How much does it cost to fix the LEDs 2,3 error on an Electrolux range?
The cost to resolve this fault depends on whether you perform the repair yourself or hire a technician. A replacement electronic control board for an Electrolux range typically costs somewhere in the range of $150 to $400 for the part alone, depending on the specific model. If you hire a technician, labor charges will add to the total, generally bringing the overall repair cost to a range of $250 to $600 or more.
