Maytag Range Error Code 1c4c

The 1c4c code means the range detected a power micro communication failure with an invalid CRC (Cyclic Redundancy Check). This indicates the main control board and the power micro processor, which manages power delivery to heating elements, cannot communicate reliably. The range logs this fault to prevent unsafe or unpredictable heating behavior.

Using the range with an active 1c4c code is not recommended. This fault involves unreliable communication between the control board and the power micro, which manages power to your heating elements. This creates a risk of elements not responding correctly to controls, including potentially failing to turn off. Disconnect the range from power until the fault is diagnosed and repaired.

Disconnecting the range from power for 60 seconds and restoring it may temporarily clear the 1c4c code, but the fault will return if the underlying hardware issue is not fixed. A CRC communication failure is a hardware-level problem, not a software glitch that resolves on its own. If the code comes back after a reset, proceed with inspecting the wiring harness and replacing the control board.

The first recommended step is replacing the main control board, as this is the most common source of the invalid CRC signal. Before ordering parts, inspect the wiring harness connecting the control board to the power micro module for burns, corrosion, or loose connectors. If a new control board does not resolve the code, the power micro module itself may need replacement. A repair technician can run diagnostics to confirm which component has failed before you order parts.

A replacement main control board for a Maytag range typically costs between $150 and $350 for the part alone, depending on the model. If you hire a technician, expect an additional $100 to $200 in labor. DIY replacement is feasible for someone comfortable working with appliance electronics, as control board swaps generally involve disconnecting wire harnesses and mounting screws, but always disconnect power before starting any repair.
