ESEC control has detected a fault condition, typically caused by surface control knobs being left in the ON position during power up or after a power failure.

First step from the service manual

Turn all surface control knobs to OFF and reset the clock with the correct time of day. If the Er message remains, contact a Servicer.

What Er means on a Electrolux range

The Er error code on an Electrolux range is generated by the ESEC (Electronic Surface Element Control) system when it detects a fault condition during power-up or after a power interruption. The ESEC control monitors the state of the surface burner control knobs at startup. If any knob is in the ON position when power is first applied or restored, the control interprets this as a potentially unsafe operating state and triggers the Er fault to prevent unintended heating element activation.

This behavior is a built-in safety feature of the ESEC control board. When utility power is restored after an outage, the control performs a self-check routine. If it reads that one or more surface element knobs are not in the OFF position, it halts normal operation and displays Er rather than allowing current to flow to the heating elements automatically. This prevents unattended elements from activating without the user's knowledge after a power interruption.

The fault can also accompany a clock reset condition. After a power failure, the range clock loses its programmed time, and the ESEC control may require both a knob position correction and a clock reset before returning to normal operation. If turning all knobs to OFF and resetting the clock does not clear the Er message, the ESEC control board itself may have an internal fault requiring professional diagnosis and likely board replacement.

Common causes of Er

  1. 01

    Surface control knob left in ON position during power-up

    Wiring / connection

    If any burner knob is not fully in the OFF position when the range powers on or power is restored, the ESEC control will trigger Er. Check all knobs and rotate each one firmly to the OFF position.

  2. 02

    Power outage or power interruption

    Wiring / connection

    A sudden loss and restoration of utility power causes the ESEC control to run its startup self-check, which can catch knobs in the wrong position or lose clock settings. Resetting the clock after restoring power is often required alongside correcting knob positions.

  3. 03

    Sticky or misaligned control knob

    Part replacement

    A knob that is worn, sticky, or not properly seated on its shaft may not return fully to the OFF position, causing the ESEC control to read it as ON at startup. Inspect each knob for resistance when turning and ensure it clicks or seats firmly at OFF.

  4. 04

    Faulty ESEC control board

    Part replacement

    If the Er message persists after all knobs are confirmed in the OFF position and the clock has been reset, the ESEC control board may have developed an internal fault. This requires professional diagnosis and likely control board replacement.

Frequently asked questions about Er

What does Er mean on a Electrolux range?
Er indicates that the ESEC (Electronic Surface Element Control) system has detected a fault, most commonly because one or more surface burner knobs were in the ON position when power was applied or restored after an outage. It is a safety feature that prevents elements from activating unattended. Turning all knobs to OFF and resetting the clock typically clears it. If the code remains, the ESEC control board may need service.
How do I fix the Er code on my Electrolux range?
Turn every surface control knob firmly to the OFF position, then reset the clock to the correct time of day. After completing both steps, check whether the Er message has cleared. If the error persists with all knobs confirmed off, contact a qualified appliance service technician to inspect the ESEC control board.
Is the Er code on an Electrolux range a safety concern?
The Er code itself is a safety response, not a danger indicator. The control is actively blocking the surface elements from operating to prevent unintended activation. Your range will not heat until the fault is cleared, so there is no immediate hazard. However, do not attempt to bypass the error; address the knob positions and clock reset as directed.
Will resetting the power clear the Er code on an Electrolux range?
Simply cutting and restoring power is unlikely to clear Er on its own because the ESEC control will perform the same startup check again. The correct reset procedure is to turn all surface knobs to OFF and reset the clock to the current time. Power cycling without correcting the knob positions will typically reproduce the same error.
How much does it cost to repair an Electrolux range showing Er?
If the fix is simply turning knobs to OFF and resetting the clock, there is no cost involved. If the ESEC control board has failed and requires replacement, repair costs including parts and labor typically range from $150 to $400 or more depending on parts availability and local service rates. Getting a diagnostic estimate from a technician before committing to the repair is recommended.
