What 1c6c means on a Maytag oven

Error code 1c6c indicates the oven's main control board attempted to communicate with its onboard EEPROM (Electrically Erasable Programmable Read-Only Memory) chip three consecutive times and received no response. The EEPROM stores critical operational data including calibration settings, user preferences, and fault history. When the control board cannot read or write to this memory, it disables all outputs for the affected oven cavity as a safety measure, meaning heating elements, relays, and other controlled components will not operate.

For a homeowner, this means your oven's main computer tried to access its internal memory chip three times and failed every time. As a result, the oven shuts down the entire cooking cavity so it cannot be used until the problem is resolved. The EEPROM is physically part of the control board itself, not a separate standalone component you can easily swap out on its own.

The root cause is almost always a failed control board. The EEPROM chip is integrated directly into the board's circuitry, so a failure in the chip, its solder connections, or the surrounding board traces all point to the same fix: replacing the entire control board assembly.

Common causes of 1c6c

  1. 01

    Failed EEPROM chip on the control board

    Part replacement

    The EEPROM chip integrated into the control board has failed internally and no longer responds to read or write commands. This is the most direct cause of a 1c6c error and requires replacing the control board.

  2. 02

    Corrupted EEPROM data or firmware

    Part replacement

    A power surge or interrupted write cycle can corrupt the EEPROM's stored data to a state where the control board cannot successfully communicate with it, triggering the three-attempt failure threshold. Replacing the control board resolves this since the new board ships with initialized firmware.

  3. 03

    Failed control board circuitry around the EEPROM

    Part replacement

    Even if the EEPROM chip itself is intact, damaged traces, failed capacitors, or other board-level failures near the EEPROM circuit can break communication and produce the same no-response condition. Board-level repair is rarely practical, making full control board replacement the standard fix.

Frequently asked questions about 1c6c

What does error code 1c6c mean on a Maytag oven?
Error code 1c6c means the oven's control board tried to communicate with its internal EEPROM memory chip three times and got no response each time. The EEPROM stores operational and calibration data the board needs to run properly. When this communication fails, the control board disables all outputs for the oven cavity, so the oven will not heat.
Can I still use my Maytag oven with error code 1c6c active?
No. When 1c6c is active, the control board disables all outputs for the oven cavity as a protective measure. The oven will not energize heating elements or any other controlled components in the affected cavity. You will need to resolve the error before the oven can be used for cooking.
How do I fix error code 1c6c on a Maytag oven?
The required fix is replacing the control board. The EEPROM that triggers this error is integrated directly into the control board assembly, so there is no separate chip to swap out. Before ordering a board, confirm the model number from the oven's label so you get the correct part. Replacing a control board involves disconnecting the power supply, removing the back or top panel to access the board, disconnecting all wire harnesses, and installing the new board in reverse order. If you are not comfortable working inside the appliance with wiring, a qualified appliance technician should handle the replacement.
How much does it cost to fix a 1c6c error on a Maytag oven?
Maytag oven control boards typically cost between $150 and $350 for the part, depending on the specific model. If you hire a technician, expect to add $100 to $200 in labor, bringing the total repair to roughly $250 to $550. DIY replacement is feasible for someone comfortable with basic appliance repair since the board swap does not require special tools, and doing it yourself eliminates the labor cost entirely.
Will resetting my Maytag oven clear error code 1c6c?
A power reset, done by unplugging the oven or tripping its breaker for one to two minutes, may temporarily clear the code, but it will return if the control board's EEPROM communication is genuinely failing. If the code comes back after a reset, the control board needs to be replaced. A reset is worth trying once, but it is not a lasting fix for a hardware-level EEPROM failure.
