LOC
Whirlpool Refrigerator
Severity: MinorWhat Does This Error Mean?
LOC on a Whirlpool refrigerator means Control Lock is active. This is not an error — it is a feature that locks the control panel buttons to prevent accidental changes. It is often activated by pressing and holding a button for 3 seconds, or it may have been turned on accidentally. Your refrigerator is working normally — you just cannot change settings until you unlock it.
Affected Models
- WRF535SWHZ
- WRF767SDHZ
- WRS325SDHZ
- WRB322DMBM
- Most Whirlpool models with touchpad or digital display controls
Common Causes
- Control Lock was intentionally activated to prevent children from changing settings
- A button was accidentally held down long enough to activate the lock
- A software glitch caused the control lock to engage on its own
- A child or pet pressed and held a button on the control panel
- A power restoration after outage caused the unit to boot into control lock mode
How to Fix It
-
Find the lock button on your control panel. It is usually labeled 'Lock', 'Control Lock', or shown with a padlock icon.
On some models the lock function is activated by holding a specific button like 'Light' or 'Max Ice' for 3 seconds.
-
Press and hold the lock button for 3 seconds. The LOC indicator should turn off.
If the first button does not work, check your owner's manual for the exact unlock procedure for your model.
-
If you cannot locate the lock button, try pressing and holding the two temperature adjustment buttons simultaneously for 3 seconds.
This combination unlocks the panel on many Whirlpool models without a dedicated lock button.
-
If the LOC indicator remains after the above steps, unplug the refrigerator for 30 seconds and restore power.
A power reset resets the control board and clears any software-triggered lock states.
-
If the control panel remains completely unresponsive after a power reset, the control board or display board may have a hardware fault.
At that point, a service call is appropriate to diagnose the display or control board.
When to Call a Professional
LOC is not a fault — no professional help is needed. Unlocking the controls takes seconds using the panel buttons. If the controls remain unresponsive after following the unlock steps, a control board reset may be needed.
Frequently Asked Questions
Is LOC dangerous or does it mean my refrigerator stopped working?
No — LOC is not a fault. Your refrigerator is cooling normally. The only thing that is locked is the control panel buttons. Food is safe and the refrigerator is operating correctly.
Why did LOC appear on its own without me pressing anything?
It is usually an accidental button press — a child, a cleaning cloth, or even a bump can hold a button long enough to engage the lock. In rare cases a software glitch after a power event can trigger it. A power reset almost always resolves this.
How do I stop LOC from activating accidentally in the future?
If you do not need the control lock feature, simply do not activate it. If it keeps turning on by itself, check that nothing is resting against the control panel. Some models allow you to disable the control lock feature through the settings menu.
