What LEDs 5,6 means on a Electrolux range

LEDs 5 and 6 illuminated on an Electrolux range indicate a shorted temperature probe circuit in the oven. The oven temperature probe is a resistance-based sensor, typically a negative temperature coefficient (NTC) or positive temperature coefficient (PTC) thermistor, that feeds real-time temperature data to the electronic control board. When the circuit goes short, the resistance drops far below the normal operating range, causing the control board to detect an invalid signal and flag the fault.

Under normal operating conditions, the oven temperature probe should measure between 1050 and 1100 ohms at room temperature. A short circuit in this probe or its wiring causes resistance to drop toward zero, which the control board interprets as an extreme or impossible temperature reading. This prevents the oven from operating safely and triggers the LED fault indication to alert the user and technician.

The most direct diagnostic step is to disconnect the probe from the control board and measure its resistance with a multimeter. A reading within the 1050 to 1100 ohm range confirms the probe itself is functional, which shifts suspicion to the wiring harness or the electronic control board. If the probe reads significantly below this range or near zero ohms, the probe has an internal short and must be replaced. If the probe checks out, the control board is the likely source of the fault and should be replaced.

Common causes of LEDs 5,6

  1. 01

    Failed oven temperature probe

    Part replacement

    The probe itself has developed an internal short, dropping its resistance well below the normal 1050 to 1100 ohm range. This is the most common cause and is confirmed by measuring the probe resistance directly with a multimeter.

  2. 02

    Damaged or pinched probe wiring harness

    Part replacement

    The wires connecting the temperature probe to the control board may be pinched, burned, or have insulation that has melted and allowed conductors to contact each other. Inspect the wiring along its entire length from the probe connector to the control board.

  3. 03

    Corroded or shorted probe connector

    Wiring / connection

    Moisture or grease buildup at the probe connector can create a low-resistance path between the two probe terminals, simulating a short even when the probe and wiring are intact. Clean or replace the connector and retest resistance.

  4. 04

    Faulty electronic control board

    Part replacement

    If the probe measures within 1050 to 1100 ohms and the wiring and connectors are in good condition, the control board's internal probe sensing circuit may have failed. Replacing the control board is the indicated next step in this scenario.

Frequently asked questions about LEDs 5,6

What does LEDs 5,6 mean on a Electrolux range?
LEDs 5 and 6 on an Electrolux range indicate a shorted oven temperature probe circuit. The control board has detected that the resistance in the probe circuit is outside the acceptable range, which prevents safe oven operation. This fault points to either a failed temperature probe, a wiring issue, or in some cases a faulty control board.
Can I fix the LEDs 5,6 error myself?
A knowledgeable DIYer can perform the primary diagnostic step by unplugging the range, disconnecting the probe, and measuring its resistance with a multimeter. If the reading falls between 1050 and 1100 ohms, the probe is good and the control board likely needs replacement. If the probe reads significantly lower or near zero ohms, replacing the temperature probe is the correct repair. Both parts are generally accessible, though working on the control board requires care around electrical components.
Is it safe to use my Electrolux range while LEDs 5,6 are showing?
No, you should not use the oven while this fault code is active. A shorted temperature probe means the control board cannot accurately monitor oven temperature, which removes a critical safety control. Operating the oven in this condition could lead to overheating. The oven should remain off until the fault is diagnosed and repaired.
Will resetting the range clear the LEDs 5,6 error?
Resetting the range by cutting power at the breaker or unplugging it may temporarily clear the displayed fault, but the error will return as soon as the control board re-checks the probe circuit. Because the fault reflects an actual electrical condition in the probe circuit, a reset does not fix the underlying problem. The probe or control board must be tested and repaired or replaced.
How much does it cost to repair the LEDs 5,6 error on an Electrolux range?
Repair costs vary depending on which component has failed. An oven temperature probe typically costs between $20 and $60 for the part, while an electronic control board can range from $150 to $350 or more depending on the model. Adding professional labor, total repair costs generally fall between $100 and $500. Diagnosing the probe first with a multimeter can help avoid the expense of replacing the control board unnecessarily.
