GE Cooktop Error Code 103

Error code 103 on a GE cooktop indicates a main board CPU failure. The central processing unit on the control board has encountered a fault it cannot recover from on its own. This error stops the cooktop from operating to prevent unsafe conditions. A power cycle is the first step, and if the code returns, the main board requires replacement.

No, you should not attempt to use the cooktop while error code 103 is active. The error indicates the main control board CPU has failed, meaning the board cannot reliably manage power delivery or element control. Operating the cooktop in this state could result in unpredictable behavior.

After installing a new main board, the inductive sensors must be recalibrated. The replacement board does not carry over calibration data from the original board, so without this step the cooktop will not correctly detect cookware on the induction zones. Skipping recalibration can result in elements that do not activate properly or behave erratically during normal use.

A power reset will clear error 103 if the cause was a temporary CPU lock-up from a voltage fluctuation or transient power event. Turn off the cooktop at the circuit breaker, wait at least one minute, and restore power. If the code returns immediately or after brief use, the main board has a hardware failure and will need to be replaced.

If a power reset does not resolve the error, the main board will need to be replaced. Parts costs for a GE induction cooktop main board typically range from $150 to $400 depending on the model. Adding professional labor, total repair costs generally fall between $250 and $600. Getting a repair estimate and comparing it to replacement cost is advisable for older units.
