What 52 means on a Kenmore range

Error code 52 on a Kenmore induction range indicates a break or open circuit condition in the inductor temperature sensor for the left rear (LR) cooking zone. The inductor temperature sensor is a thermistor or thermocouple-type device mounted within the induction housing assembly. Its job is to monitor the temperature of the induction coil and the surrounding components in real time, feeding that data back to the control board to regulate power output and prevent overheating. When the control board detects no signal or an out-of-range signal from this sensor, it interprets the condition as a sensor break and triggers error code 52 to shut down the affected zone.

The most common entry point for diagnosing this fault is the physical connection between the inductor temperature sensor and the induction housing assembly connector. A loose, corroded, or damaged connector can interrupt the circuit just as effectively as a failed sensor itself. Heat cycling over time can cause connector pins to back out or contact surfaces to oxidize, creating an intermittent or permanent open circuit.

If the connector checks out and the wiring harness shows continuity, the sensor itself is likely faulty and will need replacement. In some cases, damage to the induction housing assembly can also affect the sensor mounting position or the associated wiring, making the housing assembly another component to inspect during diagnosis.

Common causes of 52

  1. 01

    Loose or disconnected sensor connector

    Wiring / connection

    The inductor temperature sensor connector at the induction housing assembly may have worked loose due to vibration or heat cycling. Reseating the connector firmly is the first recommended step and can resolve the error without any parts replacement.

  2. 02

    Corroded or damaged connector pins

    Part replacement

    Oxidation or physical damage to the connector pins between the sensor and the induction housing assembly can create an open circuit. Inspect the pins closely for discoloration, bending, or corrosion that would prevent proper electrical contact.

  3. 03

    Failed inductor temperature sensor

    Part replacement

    The temperature sensor itself may have developed an internal break, causing it to read as an open circuit to the control board. If wiring and connectors check out, the sensor is the next component to test and replace.

  4. 04

    Damaged wiring harness

    Part replacement

    The wiring between the sensor and the control board may be cut, pinched, or broken, particularly near areas where the harness is routed close to heat sources or sharp edges inside the range. A continuity test along the harness will identify any break.

  5. 05

    Faulty induction housing assembly

    Part replacement

    If the induction housing assembly itself is damaged, it may affect the sensor mounting or the integrity of the associated wiring connections. This is a less common cause but should be evaluated if sensor and harness replacements do not resolve the fault.

Frequently asked questions about 52

What does 52 mean on a Kenmore range?
Error code 52 on a Kenmore range indicates a break in the inductor temperature sensor circuit for the left rear cooking zone. The control board is not receiving a valid signal from that sensor, so it has disabled the left rear burner as a safety measure. The issue can stem from a loose connector, damaged wiring, or a failed sensor.
Can I fix error code 52 on my Kenmore range myself?
The first step is to check whether the inductor temperature sensor connector is securely attached to the induction housing assembly, which is something a careful DIYer can attempt after unplugging the range. However, if the connector is secure and the error persists, testing the sensor and wiring harness for continuity requires a multimeter and some familiarity with appliance wiring. Replacing internal induction components is generally best handled by a qualified technician.
Is it safe to use my Kenmore range while error code 52 is showing?
When error code 52 is active, the left rear induction zone is disabled, so it cannot be used. The other cooking zones may still function normally depending on the range model. You should not attempt to bypass the error, as the sensor is a critical safety component that prevents the induction coil from overheating.
Will resetting my Kenmore range clear error code 52?
Resetting the range by unplugging it or cutting power at the breaker for a few minutes may temporarily clear the display, but the error will return if the underlying fault is still present. A reset alone does not fix a broken sensor, damaged wiring, or loose connector. The physical cause must be identified and corrected for the error to stay cleared.
How much does it cost to repair error code 52 on a Kenmore range?
Repair costs depend on what component has failed. If it is simply a loose connector, there may be little to no parts cost, though a service call typically runs between $75 and $150. If the inductor temperature sensor needs replacement, parts and labor combined often fall in the range of $150 to $350. Wiring harness or induction housing assembly replacement can push costs higher depending on parts availability.
