What 1c8c means on a Maytag range

The 1c8c error code indicates the range's control board has detected a CRC (Cyclic Redundancy Check) failure in the EEPROM's User Options data segment. The EEPROM is a small non-volatile memory chip embedded in or connected to the control board that stores settings such as clock preferences, temperature calibration offsets, and other user-configured options. A CRC is a mathematical checksum the control uses to verify stored data has not become corrupted. When the checksum does not match the stored data, the control flags a 1c8c fault rather than operate with potentially invalid settings.

For homeowners, this means the control board's memory has become corrupted or has failed. Think of it like a settings file on a computer that has gone bad and can no longer be read correctly. The board detected its own stored preferences were unreadable or damaged and threw this error to prevent operating on bad data.

This condition is typically caused by a hardware failure within the control board itself, either the EEPROM chip degrading, a power surge writing bad data to memory, or a voltage irregularity during a write cycle. Because the EEPROM is integrated into the control board assembly in most Maytag ranges, the manufacturer's first troubleshooting step is direct replacement of the control board.

Common causes of 1c8c

  1. 01

    Failed or corrupted EEPROM on the control board

    Part replacement

    The EEPROM chip on the control board has degraded or its stored User Options data has become corrupted, causing the CRC validation to fail every time the control attempts to read it. This is the primary cause and is internal to the control board assembly itself.

  2. 02

    Power surge or voltage spike during EEPROM write cycle

    Part replacement

    A power surge or sudden voltage drop while the control was writing user settings to EEPROM can leave the memory in a corrupted state. The data written during the interruption fails the CRC check on every subsequent power-up.

  3. 03

    Intermittent power supply to the control board

    Wiring / connection

    Unstable voltage reaching the control board, caused by a failing board power supply or loose wiring connections at the control, can cause repeated failed EEPROM read attempts and may have contributed to the initial data corruption.

Frequently asked questions about 1c8c

What does error code 1c8c mean on a Maytag range?
Error code 1c8c means the control board detected a CRC error in its EEPROM User Options data. The EEPROM is the memory chip that stores user settings like clock and temperature calibration. The board's checksum verification failed, indicating the stored data is corrupted or unreadable. In most cases this points to a failed control board.
How do I fix error code 1c8c on a Maytag range?
Start by disconnecting power to the range for 5 minutes and restoring it to see if the error clears. If the 1c8c code returns after the power reset, the control board will need to be replaced. This is the manufacturer's specified first troubleshooting step because the EEPROM that holds User Options data is part of the control board assembly and cannot be repaired separately.
Is it safe to use my Maytag range with a 1c8c error code?
Using the range with an active 1c8c error is not recommended. The control board's stored user settings, including any temperature calibration offsets, are confirmed corrupted or unreadable. The range may not operate with correct temperature behavior, and continuing to use it places further stress on a control board that has already detected an internal failure. Disconnect the range from power until the control is replaced.
How much does it cost to fix a 1c8c error on a Maytag range?
Control board replacement for a Maytag range typically costs between $150 and $350 for the part alone, depending on the model. Professional labor to diagnose and replace the board adds roughly $100 to $200 depending on your area. If you are comfortable working with appliance electronics and can locate the correct part using your model number, this is a DIY-feasible repair that requires removing the back panel and swapping the board connectors.
Will resetting the power fix a 1c8c error code on a Maytag range?
A power reset can clear the 1c8c code temporarily if the EEPROM corruption was caused by a one-time event like a brief power surge. Disconnect the range for 5 minutes, then restore power and check if the error returns. If the code comes back after the reset, the EEPROM data corruption is persistent and the control board must be replaced.
