What it means

The control panel has deliberately been locked against accidental use. The lit LOCK indicator is a control state, not a failed-part code.

This explanation is shared only by models whose manufacturer documents the same code, meaning, and guidance.

Press and hold PAUSE/CLEAR for about three seconds to release the lock.
After LOCK goes out, choose the intended program and press START.
If the oven still does not run, check door closure and the selected program as the troubleshooting table advises.
