What 1c81 means on a Maytag range

Error code 1c81 indicates the control board has detected a CRC (cyclic redundancy check) failure in the EEPROM memory that stores the cook profile data for the upper or single oven cavity. The EEPROM is a small non-volatile memory chip embedded in or associated with the control board that retains calibration and cooking settings even when power is removed. A CRC failure means the stored data no longer matches its expected checksum, which signals that the cook profile data has become corrupted. This typically points to a failed control board.

In plain terms, your Maytag range stores specific cooking behavior settings in a memory chip on the control board. When the range checks this memory and finds the data is scrambled or unreadable, it throws the 1c81 code rather than attempt to run the oven with bad instructions. Think of it like a corrupted settings file on a computer: the oven refuses to operate normally because it cannot trust the data guiding it.

This corruption can happen due to a power surge, a failing control board, or gradual EEPROM degradation over time. Because the cook profile is stored directly on the control board's EEPROM, the fix is replacing the control board itself rather than reprogramming the chip.

Common causes of 1c81

  1. 01

    Failed or degraded control board EEPROM

    Part replacement

    The EEPROM memory on the control board stores the oven's cook profile data. Over time or after a voltage event, this memory can degrade or corrupt, causing the CRC check to fail and triggering the 1c81 code.

  2. 02

    Power surge or voltage spike

    Part replacement

    A sudden surge in line voltage can corrupt data stored in the EEPROM on the control board. Even if the board otherwise appears functional, the stored cook profile may be unrecoverable after a surge event.

  3. 03

    Intermittent power loss during EEPROM write cycle

    Wiring / connection

    If power to the range is interrupted at the exact moment the control board is writing cook profile data to the EEPROM, the stored values can become corrupted and fail the CRC validation on the next power-up.

Frequently asked questions about 1c81

What does error code 1c81 mean on a Maytag range?
Code 1c81 means the control board detected that the cook profile data stored in its EEPROM memory has been corrupted, specifically for the upper or single oven cavity. The corruption is confirmed by a failed CRC (cyclic redundancy check), which is a built-in data validation process. The range reports this code because it cannot safely operate the oven with invalid cook profile data.
How do I fix error code 1c81 on a Maytag range?
The fix for 1c81 is replacing the control board. Since the cook profile is stored directly in the EEPROM on the control board, the corrupted data cannot be reprogrammed in the field. Locate the correct replacement board using your range's full model number, disconnect power before starting the repair, and swap the board following the wiring diagram in the service manual. If you are not comfortable working with appliance electronics, a qualified technician should handle the replacement.
Is it safe to use my Maytag range with error code 1c81 active?
You should not use the upper or single oven cavity while 1c81 is active. The control board cannot verify the cook profile data it uses to regulate oven operation, which means temperature control and cooking behavior may be unpredictable. Surface burners on a gas or electric range may still function, but the affected oven should remain off until the control board is replaced.
Will resetting the control board clear the 1c81 code on a Maytag range?
A power reset may temporarily clear the display, but 1c81 will return if the underlying EEPROM corruption is still present. Because the cook profile data stored in the EEPROM is what failed the CRC check, cycling power does not repair the corrupted memory. The code will persist until the control board is replaced.
How much does it cost to fix a Maytag range with error code 1c81?
A replacement Maytag oven control board typically costs between $150 and $350 depending on the model. If you hire a technician, expect an additional $100 to $200 in labor, bringing the total repair to roughly $250 to $550. The repair itself is moderate in difficulty for a DIYer comfortable with appliance electronics: it involves disconnecting power, removing the back panel or control panel housing, unplugging wire harnesses, and swapping the board.
