What 52 means on a Electrolux range

Error code 52 on an Electrolux induction range indicates a break or open circuit in the inductor temperature sensor located at the left rear cooking zone. This sensor is a negative temperature coefficient (NTC) thermistor embedded within the inductor assembly and is responsible for monitoring the temperature of the induction coil during operation. The control board continuously reads the resistance of this sensor across its blue signal wires, and when it detects an open circuit or a resistance value that falls outside the expected range, it triggers error 52 and disables the affected zone as a protective measure.

At room temperature, the inductor temperature sensor should measure approximately 1000 ohms across its blue wires. A break in the sensor circuit means the resistance reads as infinite or drastically outside this specification, which the control board interprets as a sensor failure rather than a valid temperature reading. This open-circuit condition can result from a physically broken sensor element, a disconnected or corroded harness connector at the Induction Housing Assembly, or internal failure of the inductor assembly itself.

Because the temperature sensor is integrated into the inductor assembly rather than being a separately serviceable component, diagnosis focuses on confirming connector integrity first before condemning the entire inductor. If the connector is secure and the resistance across the blue sensor wires does not read approximately 1000 ohms at room temperature, the inductor assembly must be replaced. Continued operation without addressing this fault is not possible, as the control board will keep the left rear zone locked out until the fault is resolved.

Common causes of 52

  1. 01

    Disconnected or loose sensor connector

    Wiring / connection

    The temperature sensor connector at the Induction Housing Assembly may have worked loose due to vibration or improper reassembly. Inspect the connector on the blue sensor wires and reseat it firmly to rule this out before replacing any parts.

  2. 02

    Failed inductor temperature sensor

    Part replacement

    The NTC thermistor inside the inductor assembly can fail open, causing infinite resistance instead of the expected approximately 1000 ohms at room temperature. If the connector is seated properly and the resistance reading is not near 1000 ohms, the sensor has failed and the inductor assembly must be replaced.

  3. 03

    Damaged sensor wiring (blue wires)

    Part replacement

    The blue wires connecting the temperature sensor to the control harness can be pinched, cut, or burned, creating an open circuit. Visually trace the blue wires from the inductor to the connector and look for visible damage or breaks.

  4. 04

    Corroded or damaged connector terminals

    Wiring / connection

    Moisture or heat exposure can corrode the connector terminals at the Induction Housing Assembly, increasing resistance to the point where the control board reads an open circuit. Check for discoloration, corrosion, or melted plastic at the connector.

  5. 05

    Faulty induction control board

    Part replacement

    In rare cases, the control board itself may incorrectly report a sensor break even when the sensor and wiring are intact. This should only be considered after confirming the sensor measures approximately 1000 ohms and all wiring and connections are sound.

Frequently asked questions about 52

What does 52 mean on a Electrolux range?
Error code 52 indicates a break or open circuit detected in the inductor temperature sensor for the left rear cooking zone. The control board monitors this sensor's resistance across two blue wires and expects a reading of approximately 1000 ohms at room temperature. When the circuit reads as open or far outside that range, the board shuts off the left rear zone and displays the fault. The problem is typically a loose connector, damaged wiring, or a failed inductor assembly.
Can I fix error 52 on my Electrolux induction range myself?
A knowledgeable DIYer can start by checking whether the temperature sensor connector at the Induction Housing Assembly is securely seated, which requires accessing the underside of the cooktop. If the connector is secure, use a multimeter to measure the resistance across the blue sensor wires: the reading should be approximately 1000 ohms at room temperature. If the reading is open or significantly off, the inductor assembly needs to be replaced, which involves disconnecting power and removing the cooktop glass and internal components.
Is it safe to keep using my Electrolux range with error 52 displayed?
The left rear induction zone will be locked out by the control board and will not energize while error 52 is active, so there is no active heating hazard from that specific zone. The rest of the range's cooking zones and oven functions are generally unaffected. However, you should not attempt to bypass the fault, and the issue should be repaired promptly to restore full functionality.
Will resetting my Electrolux range clear error code 52?
Cutting power to the range at the breaker for a few minutes may temporarily clear the error display, but the fault will return immediately once the control board checks the sensor circuit again. Because error 52 points to a hardware problem, either a disconnected connector, broken wire, or failed sensor, a reset alone will not resolve it. The underlying cause must be diagnosed and repaired for the code to stay cleared.
How much does it cost to repair error code 52 on an Electrolux induction range?
If the fix is simply reseating a loose connector, there is no parts cost involved. If the inductor assembly needs to be replaced, parts alone typically range from around 80 dollars to over 200 dollars depending on the model. Adding professional labor, total repair costs can range from approximately 150 dollars to 400 dollars or more. Getting a diagnosis from a qualified technician before ordering parts is advisable, since the control board could also be involved in rare situations.
