Maytag Oven Error Code 1c4c

The 1c4c code indicates a Power Micro communication failure in the UH control board. The UH control board is a combined unit that handles both power management and user interface functions. When its internal processors lose communication with each other, the oven generates this code. The problem originates inside the board itself, not in external sensors or wiring.

Using the oven with an active 1c4c code is not advisable. The failure involves the power management processor inside the UH control board, which means the oven cannot reliably regulate power or respond to controls. Operating it in this state risks unpredictable behavior including failure to maintain correct temperature or improper shutdown. Discontinue use until the control board is replaced.

A power reset can clear the 1c4c code if the fault was caused by a temporary software glitch or a brief power fluctuation. Disconnect the oven from power for at least five minutes, then restore power and see if the code returns. If 1c4c reappears after the reset, the UH control board has a hardware failure and a reset will not provide a lasting fix. Repeated resets on a board with an internal processor fault will not prevent the code from returning.

Start by disconnecting power to the oven for five minutes to allow a hard reset. Restore power and check if the code returns. If 1c4c comes back, inspect the wiring harness connectors to the control board for looseness, corrosion, or burn marks, and check that the oven is receiving correct supply voltage. If none of those resolve it, the UH control board requires replacement. This is the standard fix Maytag specifies for this code.

A replacement Maytag UH control board typically costs between $150 and $350 depending on the specific model. If you hire a technician, expect to add $100 to $200 in labor, bringing total repair costs to roughly $250 to $550. The board swap itself is a moderately involved repair requiring removal of the back panel or control console depending on the model. Experienced DIYers with basic appliance repair skills can complete it, but if you are not comfortable working around oven wiring, having a technician handle it is a reasonable choice.
