Whirlpool Microwave LOC — What It Means & How to Fix It
Also shown as L, Padlock on some models.
LOC, L or a padlock icon means Control Lock is enabled — depending on model, press and hold Cancel for 3 seconds or Start for 5 seconds to unlock.
What this code means
Whirlpool says the Control Lock feature is enabled and gives two model-dependent ways to turn it off: hold the Cancel key for 3 seconds, or hold the Start key for 5 seconds.
Which key unlocks depends on the model; see the owner's manual. A door icon instead of a padlock relates to the 2-step door feature.
Most likely causes
| Cause | How likely | DIY-fixable? |

| Control Lock set on purpose | Common | Yes — no tools |
| Key held while cleaning | Common | Yes — no tools |
