What 76 means on a Kenmore range

Error code 76 on a Kenmore induction range signals a communication failure within the Induction Housing Assembly on the right side of the cooktop. Specifically, the control system has lost reliable data communication between the ESEC-UIB (Electronic Surface Element Control User Interface Board) and the Large Filter Circuit Board. The right side cooking zones depend on this communication link to receive power commands, temperature regulation signals, and safety feedback. When the signal is interrupted or corrupted, the control system flags error 76 and disables the affected zones to prevent unsafe operation.

The communication path runs through a wiring harness connecting the ESEC-UIB at its P9 connector to the Large Filter Circuit Board at connectors X20 or X14. Any break, corrosion, or loose connection along this harness can disrupt the data signal. The Large Filter Circuit Board itself conditions power for the induction coils and participates in the communication loop, so an internal board failure can also trigger this code. Physical damage to the harness from heat exposure near the induction housing is a known contributing factor.

Diagnosing this error begins with a careful inspection of the communication harness and both connector points. Technicians should check for bent or pushed-back pins, corrosion on the connector contacts, and any visible damage to the harness insulation. If the harness and connectors are intact, testing continuity through the harness and evaluating the Large Filter Circuit Board for failure becomes the next priority. The ESEC-UIB should also be assessed if board-level faults are suspected after ruling out wiring issues.

Common causes of 76

  1. 01

    Loose or disconnected harness connector

    Wiring / connection

    The communication harness between the ESEC-UIB P9 connector and the Large Filter Circuit Board connectors X20 or X14 may have come loose due to vibration or improper seating. Inspect both connectors for secure engagement and listen for a positive click when reseating them.

  2. 02

    Corroded or damaged connector pins

    Wiring / connection

    Moisture or heat exposure inside the induction housing can cause corrosion on the connector pins at P9, X20, or X14, degrading the communication signal. Visually inspect the pins for oxidation, discoloration, or physical damage.

  3. 03

    Damaged communication harness

    Part replacement

    The wiring harness running between the ESEC-UIB and the Large Filter Circuit Board can suffer insulation damage or broken conductors from prolonged heat exposure near the induction housing. A continuity test across the harness will confirm whether a break is present.

  4. 04

    Failed Large Filter Circuit Board

    Part replacement

    If the harness and connectors check out correctly, the Large Filter Circuit Board itself may have failed internally, preventing it from communicating with the ESEC-UIB. Board failure often requires replacement rather than repair.

  5. 05

    Failed ESEC-UIB

    Part replacement

    In less common cases, the ESEC-UIB itself may have a fault at the P9 communication port or internally, causing it to fail to transmit or receive signals. This is typically diagnosed after all wiring and the Large Filter Circuit Board have been ruled out.

Frequently asked questions about 76

What does 76 mean on a Kenmore range?
Error code 76 on a Kenmore induction range indicates a communication error in the Induction Housing Assembly affecting the right side cooking zones. The control system has detected that the ESEC-UIB and the Large Filter Circuit Board are not communicating properly through their shared wiring harness. The right side burners will typically be disabled until the fault is resolved.
Can I fix error code 76 on my Kenmore range myself?
Some DIYers comfortable with appliance repair can attempt to inspect and reseat the communication harness connectors at the ESEC-UIB P9 port and the Large Filter Circuit Board connectors X20 and X14, which may resolve the error if the cause is simply a loose connection. However, accessing these components requires disassembling part of the range, and if the fault lies with a damaged harness or a failed circuit board, replacement parts and additional technical skill are needed. If you are not confident working around high-voltage induction electronics, a qualified technician is the safer choice.
Is it safe to keep using my Kenmore range while error 76 is displayed?
The right side cooking zones will typically be disabled when error 76 is active, so using them is not possible in most cases. The left side zones may continue to function, but it is advisable to resolve the error before relying on the range for regular cooking. Operating appliances with active communication faults in the control system is not recommended, as the root cause could worsen over time.
Will resetting my Kenmore range clear error code 76?
A power reset by unplugging the range or cycling the circuit breaker for several minutes may temporarily clear the error code if the fault was caused by a transient signal issue. However, if the underlying cause is a loose connector, damaged harness, or failed circuit board, the code will return once the range powers back up and attempts communication again. A reset alone is not a repair.
How much does it cost to repair error code 76 on a Kenmore induction range?
Repair costs vary depending on the root cause. If only the harness connectors need reseating, a service call fee in the range of $75 to $150 may cover the visit. If a replacement communication harness is needed, parts and labor could bring the total to $150 to $300. A Large Filter Circuit Board replacement is typically the most expensive scenario, with parts and labor potentially ranging from $250 to $500 or more depending on parts availability and local labor rates.
