Maytag Cooktop Error Code 6 LEDs flash

The 6 LEDs flash error on a Maytag cooktop indicates an analog-to-digital (A/D) conversion failure on the electronic control board. The A/D converter is a critical circuit within the control board that translates analog sensor signals, such as temperature readings and touch input voltages, into digital data the microprocessor can interpret. When this conversion process fails or produces out-of-range values, the control board locks itself out entirely to prevent unsafe operation. No audible alarm accompanies this fault, so the flashing LED pattern is the only user-facing indication that a failure has occurred.

This type of failure is internal to the control board itself. Unlike some error codes that point to external sensors or wiring harnesses, an A/D failure means the fault lies within the board's onboard circuitry. Possible contributing factors include voltage irregularities from the power supply corrupting the A/D converter, component-level failures such as a degraded reference voltage circuit or failed capacitors on the board, and heat-related damage from prolonged high-temperature operation near the cooktop surface. Moisture intrusion from boil-overs is another common contributor to board-level failures in cooktops.

Because the A/D failure locks the electronic control completely, the cooktop will not respond to user input and cannot be restored to operation through a simple reset. The control board must be replaced to resolve this fault. There is no field-level repair procedure for the A/D converter circuit itself, as this requires component-level board repair that is not practical in most service scenarios.
