What 55 means on a Kenmore range

Error code 55 on a Kenmore induction range indicates a break or open circuit in the inductor temperature sensor circuit for the right front (RF) cooking zone. The inductor temperature sensor is a thermistor-based component mounted within the induction housing assembly that continuously monitors the temperature of the induction coil during cooking. When the control board detects an open circuit or an out-of-range resistance reading from this sensor, it triggers error code 55 and disables the affected zone to prevent uncontrolled heating.

The most common cause of this fault is a loose or disconnected wiring harness between the inductor temperature sensor and the induction housing assembly connector. Vibration during use, previous service work, or factory assembly issues can allow the connector to partially or fully separate. Because of this, the first diagnostic step is always to confirm the sensor connector is fully seated at the induction housing assembly before replacing any components.

If the connector is secure, the fault likely lies in the sensor itself, which may have failed internally due to heat cycling, physical damage, or manufacturing defect. A broken sensor will present as infinite resistance across its terminals rather than the expected thermistor resistance curve. The wiring harness between the sensor and control board should also be inspected for pinched, burned, or broken wires. If the sensor, harness, and connector all check out, the induction control board may be misreading the circuit and could require replacement.

Common causes of 55

  1. 01

    Loose or disconnected sensor connector

    Wiring / connection

    The wiring connector between the inductor temperature sensor and the induction housing assembly may have come loose or pulled free. Inspect the connector at the induction housing assembly and press it firmly until it clicks into place.

  2. 02

    Failed inductor temperature sensor

    Part replacement

    The thermistor inside the inductor temperature sensor may have failed internally, creating an open circuit. A failed sensor will show infinite or wildly out-of-range resistance when tested with a multimeter across its terminals.

  3. 03

    Damaged or broken wiring harness

    Part replacement

    The wiring between the sensor and the control board may have a broken conductor, burn mark, or pinch point that interrupts the circuit. Visually inspect the full length of the harness for any visible damage.

  4. 04

    Corroded or burnt connector terminals

    Part replacement

    Heat and moisture exposure can cause the connector terminals to corrode or char, increasing resistance to the point where the control board reads the circuit as open. Inspect the connector pins closely for discoloration or buildup.

  5. 05

    Faulty induction control board

    Part replacement

    If the sensor, harness, and connectors all test correctly, the induction control board itself may be misinterpreting the sensor signal. Control board replacement is typically a last-resort diagnosis after all other components are confirmed good.

Frequently asked questions about 55

What does 55 mean on a Kenmore range?
Error code 55 on a Kenmore induction range indicates a break or open circuit in the inductor temperature sensor for the right front cooking zone. The control board cannot read a valid signal from the sensor, so it disables that burner as a safety precaution. The issue is usually a disconnected connector, a failed sensor, or a damaged wiring harness.
Can I fix error code 55 on my Kenmore range myself?
The first step is to check that the sensor connector is fully seated at the induction housing assembly, which requires accessing the interior of the range. If reconnecting the connector does not clear the error, testing and replacing the inductor temperature sensor or wiring harness is within reach for a confident DIYer with a multimeter and basic appliance repair tools. Control board replacement is more complex and may be better suited for a professional technician.
Is it safe to use my Kenmore range while error code 55 is showing?
The right front induction zone will be disabled while error code 55 is active, so cooking on that burner is not possible. Other cooking zones on the range may still function normally. It is not recommended to attempt to bypass or ignore the fault, as the temperature sensor is a key safety component for the induction system.
How much does it cost to repair error code 55 on a Kenmore range?
If the fix is simply reseating a loose connector, there is no parts cost. Replacing the inductor temperature sensor typically costs between $20 and $80 for the part, depending on the specific model. If the induction control board requires replacement, parts and labor combined can range from $150 to $400 or more.
Will resetting my Kenmore range clear error code 55?
Resetting the range by disconnecting power for a few minutes may temporarily clear the error code, but it will return as soon as the control board checks the sensor circuit again. The underlying issue, whether a loose connector, failed sensor, or damaged wiring, must be physically repaired before the error code will stay cleared.
