Verify that the Litton microwave is plugged in to a working power supply. Replace the fuse or circuit breaker as necessary.
Ensure that a cooking time has been entered and "Start" was pressed if the microwave has power but is not working. The door must be firmly closed in order for it to function.
Press "Stop/Clear" if the microwave is not starting after time, power or other settings have been entered. Press "Stop/Clear" again. This will reset the microwave. Choose a new time or power setting and press "Start."
Wipe down the glass turntable and the rollers if the turntable is unstable or making noise as it turns.
Press "Pause" during the cooking process and stir the food if food is cooking unevenly.
