What the LOCKED error code actually means

Your Frigidaire microwave's control panel has been locked, which is why the buttons aren't responding and you see an 'L' on the display. This is a built-in child lock feature, not a malfunction. To unlock it, press and hold the CLEAR/OFF button for about 3 seconds and the microwave will return to normal operation.

Questions people ask about LOCKED

What does LOCKED mean on a Frigidaire microwave?
The LOCKED indicator, shown as an 'L' on the display, means the control panel lock feature has been activated. All keypad buttons are disabled while this lock is engaged. This is a built-in function designed to prevent accidental use and is not a sign of a malfunction or component failure.
Is it safe to use my Frigidaire microwave when it shows LOCKED?
The microwave is safe, but it will not operate while the control lock is active. No cooking functions can be started in this state. Simply unlock the control panel using the CLEAR/OFF button and the unit will function normally.
How much does it cost to fix a Frigidaire microwave stuck in LOCKED mode?
In most cases, clearing the LOCKED condition costs nothing since it is resolved by pressing and holding CLEAR/OFF for 3 seconds. If a stuck keypad button or a faulty control board is preventing the unlock sequence from working, repair costs could range from roughly $50 to $200 or more depending on parts and labor in your area.
How do I fix the LOCKED condition on my Frigidaire microwave?
Press and hold the CLEAR/OFF button for approximately 3 seconds. The 'L' should disappear from the display and the control panel will return to normal operation. If this does not work on the first attempt, release the button fully and try again, holding for the full 3 seconds.
Will unplugging my Frigidaire microwave clear the LOCKED indicator?
Unplugging the microwave and restoring power may or may not clear the lock, depending on how the control board retains its state. The correct and reliable method is to press and hold CLEAR/OFF for about 3 seconds. If the lock persists after multiple attempts, inspect the keypad for stuck buttons.
