GE Range Error Code F141

The F141 error code on a GE range indicates that the slave microprocessor is not functioning correctly. Modern GE ranges with electronic controls often use a dual-processor architecture, where a primary (master) microcontroller handles the main user interface and coordination tasks, while a secondary (slave) microcontroller manages specific subsystems such as oven temperature regulation, burner control, or safety monitoring. When the master processor loses communication with the slave processor or detects that the slave is unresponsive, it triggers the F141 fault code.

The slave microprocessor is typically integrated into the main control board or, in some configurations, a secondary control board. Causes of this fault include internal failure of the slave processor chip itself, corrupted firmware, loss of the communication signal between the two processors, or power supply irregularities that prevent the slave processor from initializing properly. A failed or degraded main control board is the most common hardware source of this fault.

Because the slave processor plays a role in core cooking and safety functions, the range may become partially or fully inoperative when this error is active. Diagnosis generally involves inspecting the control board for visible damage such as burned components or swollen capacitors, verifying stable power supply voltage to the board, and checking wiring harness connections between any dual-board configurations. In most cases, resolving F141 requires replacement of the affected control board.
