Whirlpool Range LOC Error Code — What It Means
When your Whirlpool range displays LOC, Lock, or Locked, it is not reporting a failure. The message means the Control Lock (or Control Lockout) feature is enabled. While locked, the control panel will not accept commands, and pressing any button may cause LOC to flash again. Whirlpool designs this feature to prevent accidental use or changes, especially around children. The display will clear as soon as you disable the lock using your model’s unlock sequence.
Common Causes
- Control Lock was accidentally activated Someone pressed the lock key combination during cleaning or by leaning against the panel.
- Brief power interruption A glitch or momentary outage can leave the control in a locked state until you reset the unit.
- Wrong unlock button sequence Different Whirlpool models use different key combinations, so the unit appears stuck if you press the wrong button.
- Child or pet pressed the panel Unintended contact with the touchpad can trigger the lock function without your knowledge.
Step-by-Step Fix
- Confirm the display reads LOC, Lock, or Locked and not an F-code or door-lock fault, because Whirlpool treats this as a feature message rather than a component failure.
- Hold the START or ENTER button for 5 seconds to toggle the Control Lock off on most models, and watch for the LOC message to disappear.
- Check your owner’s manual if holding START does not work, because some models require a different key combination (such as holding two buttons together) to unlock the control.
- Turn off the circuit breaker(s) feeding the range for 1 minute if the display remains locked, then restore power and monitor the display for 1 minute to confirm LOC does not return.
- Test the control panel by selecting a cooking function after power is restored to verify that commands now register and the oven or burners respond.
- If LOC clears but the keypad is still unresponsive, you are facing a separate control-board or user-interface issue that goes beyond the lock feature itself and requires further diagnosis.
- Document your model number and consult Whirlpool’s model-specific manual if none of these steps clear the lock, because unlock procedures can vary across product lines.
Parts Often Needed
| Part | Notes |
|---|---|
| Whirlpool Range Control Board (Main ERC) | Amazon | Only needed if the control will not unlock after reset and shows signs of logic failure, not for a simple LOC condition. |
| Whirlpool Range User Interface / Touchpad Overlay | Amazon | Required if buttons remain unresponsive after LOC is cleared and you have ruled out a locked state. |
When to Call a Pro
If holding START for 5 seconds and performing a 1-minute breaker reset both fail to clear the LOC message, or if the display clears but the keypad still will not accept any commands, call a qualified appliance technician. A persistent lock condition after power cycling can indicate a stuck button, a failing user interface, or a control-board logic fault that requires diagnostic tools and possibly board-level replacement. Because LOC itself is a feature rather than a fault code, ongoing problems point to hardware issues beyond the normal lock function.
