What Convection Roast + Clean (LEDs 3,5) means on a Electrolux range

The Convection Roast + Clean LED indicator combination (LEDs 3 and 5) on an Electrolux range signals that the control system has detected a shorted temperature probe circuit. The oven temperature probe, also called the RTD (resistance temperature detector) sensor, is a thermistor-based component that monitors oven cavity temperature and feeds that data back to the electronic control board. Under normal operating conditions, the probe should read between 1050 and 1100 ohms at room temperature. When the control board detects resistance that falls significantly below this range, it interprets the condition as a short circuit and triggers this fault code.

A shorted probe circuit means that the resistance in the sensor circuit has dropped too low, which causes the control board to receive inaccurate temperature readings. This can happen due to a failed probe element, damaged wiring that has allowed two conductors to contact each other, or a connector that has corroded or melted and created an unintended electrical path. In some cases, the probe itself is physically intact but the wiring harness running from the probe to the control board has been pinched, burned, or compromised near a heat source inside the range cavity.

Diagnosing this fault begins with measuring the resistance at the oven temperature probe using a multimeter. Disconnect the probe leads and measure resistance directly at the probe terminals. A reading within the 1050 to 1100 ohm range confirms the probe is functioning correctly, which then points to the electronic control board as the faulty component. A reading significantly below 1050 ohms, or a near-zero reading indicating a direct short, confirms probe or wiring failure.

Common causes of Convection Roast + Clean (LEDs 3,5)

  1. 01

    Failed oven temperature probe

    Part replacement

    The probe element itself has internally shorted, causing resistance to drop well below the normal 1050 to 1100 ohm range. This is the most common cause and is confirmed by measuring resistance directly at the probe terminals with a multimeter.

  2. 02

    Damaged probe wiring harness

    Part replacement

    The wires connecting the temperature probe to the control board may be pinched, melted, or burned, allowing the two conductors to contact each other and creating a short. Visually inspect the harness along its full length inside the oven cavity and behind the back panel.

  3. 03

    Corroded or melted probe connector

    Part replacement

    The connector that joins the probe leads to the wiring harness can corrode or melt due to heat exposure, creating an unintended electrical path that reads as a short. Inspect the connector body and terminals for discoloration, melting, or corrosion buildup.

  4. 04

    Faulty electronic control board

    Part replacement

    If the probe and all wiring measure within spec, the control board itself may be misreading the probe circuit due to an internal component failure. Board failure is considered only after the probe and harness have been confirmed to be in good condition.

Frequently asked questions about Convection Roast + Clean (LEDs 3,5)

What does Convection Roast + Clean (LEDs 3,5) mean on a Electrolux range?
This LED combination indicates that the electronic control board has detected a shorted temperature probe circuit in the oven. The oven temperature probe is responsible for measuring the internal oven temperature and reporting it back to the control board. When the probe circuit resistance falls outside the expected 1050 to 1100 ohm range, the board flags this fault to prevent unsafe or inaccurate oven operation.
Can I fix the Convection Roast + Clean (LEDs 3,5) error myself?
A knowledgeable DIYer can diagnose this fault by testing the oven temperature probe resistance with a multimeter. Disconnect the probe and measure resistance at its terminals; a reading between 1050 and 1100 ohms means the probe is good and the control board likely needs replacement. If the reading is significantly below 1050 ohms or near zero, the probe or its wiring harness needs to be replaced. Both the probe and the control board are serviceable components, though board replacement requires careful handling of wiring connectors.
Is it safe to use my Electrolux range while this error is displayed?
It is not recommended to continue using the oven while this fault is active. A shorted temperature probe means the control board cannot accurately monitor oven temperature, which could result in the oven overheating or failing to regulate heat properly. The range's surface burners may still function, but the oven should remain out of service until the fault is diagnosed and repaired.
Will resetting the range clear the Convection Roast + Clean (LEDs 3,5) error?
Resetting the range by cutting power at the breaker or unplugging it may temporarily clear the fault display, but the error will return as soon as the control board re-evaluates the probe circuit and detects the short again. A reset does not address the underlying hardware problem. Permanent resolution requires testing the probe resistance and replacing the faulty component, either the probe or the control board.
How much does it cost to repair the Convection Roast + Clean (LEDs 3,5) error on an Electrolux range?
Repair costs vary depending on which component is faulty. Replacing the oven temperature probe is typically the less expensive fix, with parts generally ranging from $20 to $60 and professional labor adding $75 to $150 depending on your area. If the electronic control board requires replacement, parts alone can range from $150 to $350 or more, with total professional repair costs potentially reaching $250 to $500. Diagnosing the probe first with a multimeter can help avoid purchasing an unnecessary control board.
