Jenn-Air Range Error Code 1c81

Error code 1c81 indicates an EEPROM CRC error in the upper cavity cook profile data. The control board has detected that the memory storing the upper oven's cooking profile information is corrupted or invalid. This is a control board memory fault rather than a sensor or wiring issue. The range displays this code to prevent operation with unreliable cooking data.

Using the upper oven while this error is active is not recommended. The error means the control board cannot verify the integrity of the upper cavity cook profile data, which could result in improper temperature management during cooking cycles. It is best to avoid using the upper oven until the fault is diagnosed and resolved.

A power reset, performed by unplugging the range or turning off the circuit breaker for a few minutes, may clear the error if the EEPROM corruption resulted from a power interruption during a write cycle. However, if the underlying EEPROM chip or control board is damaged, the error code will return after the reset. A persistent 1c81 code after resetting points to a hardware failure requiring part replacement.

You can attempt a hard reset by disconnecting the range from power for several minutes, then restoring power to see if the error clears. If the EEPROM data corruption was caused by a momentary power interruption, a reset may resolve it. However, if the EEPROM chip itself has degraded or the control board has failed, the electronic oven control board will need to be replaced, which is a more involved repair.

If the repair requires a new electronic oven control board, part costs typically range from around $150 to $400 or more depending on the specific model. Professional labor to diagnose and replace the control board can add another $100 to $250. If a simple power reset resolves the issue, there is no parts cost involved.
