After performing voltage measurements, disconnect power before servicing.

Failure to follow these instructions can result in death or electrical shock.

Voltage Measurement Safety Information

When performing live voltage measurements, you must do the following: Verify the controls are in the off position so that the appliance does not start when energized. Allow enough space to perform the voltage measurements without obstructions. Keep other people a safe distance away from the appliance to prevent potential injury. Always use the proper testing equipment. After voltage measurements, always disconnect power before servicing.

IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics

ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress.

Use an antistatic wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the appliance -OR-

Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.

Before removing the part from its package, touch the antistatic bag to a green ground connection point or unpainted metal in the appliance.

Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.

When repackaging failed electronic control assembly in antistatic bag, observe above instructions.

Failure/Error Codes Analysis

NOTE: Cycle power (power off, then wait 10 seconds before powering On) before starting any test. After powering On, wait 1 minute then verify that the failure appears again. When an error occurs, the “FxEx” code will be shown on the display. The following illustration shows the F6E0 error code after powering the unit on. See the “Diagnostics” section for an illustration of the error code while in the Diagnostics Mode.

The error code is shown when it occurs and will remain lit while the cooktop is On. If the cooktop is in Standby Mode, the error will not be displayed. If the user tries to power the cooktop on, the error code will appear if the error has not been resolved.

The possible error codes are:
