What C-22 means on a Electrolux range

The C-22 error code on an Electrolux range indicates that the control board has detected a short circuit in the oven temperature sensor circuit. The oven temperature sensor, also called an RTD (resistance temperature detector), is a thermistor-based probe mounted inside the oven cavity. It continuously sends resistance readings to the electronic control board, which uses those readings to regulate oven temperature. At room temperature, a properly functioning sensor should measure approximately 1080 ohms. When the control detects resistance that is significantly below the expected range, it interprets this as a short circuit and triggers the C-22 fault.

A short circuit in this context typically means that the two signal wires in the sensor circuit are making unintended contact with each other or with a grounded metal surface, causing resistance to drop well below the normal operating range. This can occur within the sensor probe itself, along the wiring harness that connects the sensor to the control board, or at the connector terminals. Physical damage to the harness from heat exposure, pinching behind the oven cavity, or rodent activity are common contributing factors.

Diagnosing this fault begins with disconnecting power to the appliance and removing the back cover to access the sensor harness. Unplugging the sensor connector from the control board and measuring resistance directly at the sensor leads with a multimeter is the definitive first step. A reading at or near 1080 ohms at room temperature confirms the sensor is intact and the problem may lie in the harness or control board. A reading near zero ohms or a direct short confirms sensor failure and replacement is required.

Common causes of C-22

  1. 01

    Failed oven temperature sensor

    Part replacement

    The sensor probe itself has developed an internal short circuit, causing resistance to drop far below the expected 1080 ohms at room temperature. This is the most common cause and is confirmed by measuring the sensor resistance directly at its leads after disconnecting the harness from the control board.

  2. 02

    Damaged sensor wiring harness

    Part replacement

    The wiring that runs from the sensor probe through the oven cavity to the control board can become pinched, heat-damaged, or abraded over time, causing the two conductors to short against each other or against a grounded chassis surface.

  3. 03

    Corroded or shorted connector terminals

    Wiring / connection

    The connector that joins the sensor harness to the control board can accumulate moisture or debris, leading to a short between the signal pins. Inspecting the connector for discoloration, corrosion, or melted plastic can help identify this issue.

  4. 04

    Control board fault

    Part replacement

    In less common cases, the control board itself may have a failed input circuit that incorrectly reports a short even when the sensor and harness measure correctly. If sensor resistance reads 1080 ohms at room temperature and the harness shows no damage, the control board should be evaluated.

Frequently asked questions about C-22

What does C-22 mean on a Electrolux range?
C-22 on an Electrolux range indicates a short circuit has been detected in the oven temperature sensor circuit. The control board monitors the sensor's resistance to regulate oven temperature, and this code triggers when resistance drops well below the expected value of approximately 1080 ohms at room temperature. The fault points to a problem in the sensor probe, the wiring harness, or the connector between the two. The oven will not operate normally until the fault is resolved.
Can I fix the C-22 error myself?
A knowledgeable DIYer can diagnose and often fix C-22 by disconnecting power, removing the back cover, and using a multimeter to measure resistance at the sensor leads. If the reading is far below 1080 ohms, the sensor needs replacement. If the sensor measures correctly, inspecting the harness for visible damage or a corroded connector is the next step. Sensor replacement on most Electrolux ranges is straightforward and does not require specialized tools.
Is it safe to use my Electrolux range while C-22 is displayed?
It is not recommended to use the oven while C-22 is active. A shorted temperature sensor means the control board cannot accurately read oven temperature, which removes the primary safeguard against overheating. Continued use in this state could result in overcooked food, component damage, or an unsafe operating condition. The surface burners on a gas or electric range may still function, but the oven should remain off until the fault is repaired.
Will resetting the power clear the C-22 error?
Resetting power by unplugging the range or switching off the circuit breaker may temporarily clear the display, but C-22 will return as soon as the control board checks the sensor circuit again. The code is triggered by a real electrical condition, specifically a short circuit in the sensor or its wiring, and it will persist until the underlying hardware problem is corrected.
How much does it cost to repair a C-22 error on an Electrolux range?
If only the oven temperature sensor needs replacement, parts typically cost between $20 and $60 depending on the specific model, and the repair is manageable as a DIY project. If a professional technician is needed, total repair costs including labor generally range from $100 to $250. In the less common scenario where the control board is at fault, parts and labor costs can range from $200 to $450 or more.
