What the LOCKED error code actually means

Your microwave is displaying LOCKED because the child lock feature has been turned on, which prevents any buttons from working until it is turned off. This is not a malfunction or error, just a safety feature that someone in your home activated, possibly by accidentally holding down a button. To use your microwave again, you will need to unlock the control panel, which is usually done by pressing and holding a specific button for a few seconds.

Questions people ask about LOCKED

How do I fix LOCKED on a GE microwave?
Press and hold the CLEAR/OFF button for approximately 3 seconds. The LOCKED display should disappear and the control panel will resume normal operation. If the display does not clear, try unplugging the microwave for 60 seconds and then repeating the sequence after power is restored.
Can I still use my GE microwave when it shows LOCKED?
No, you cannot start or operate the microwave while LOCKED is displayed because all control panel inputs are disabled. The appliance is safe and no damage is occurring, but you must unlock the control panel using the CLEAR/OFF button hold sequence before any cooking functions will respond.
How much does it cost to fix the LOCKED code on a GE microwave?
If the lock was activated by a user, clearing it costs nothing and takes seconds. If a faulty touchpad is causing the lock to re-engage on its own, a replacement touchpad membrane costs roughly $30 to $80 in parts and is a moderate DIY repair requiring basic disassembly. A control board replacement runs $80 to $150 in parts, and professional labor adds $100 to $200 depending on your area. Given those costs, compare repair prices against the age and value of the unit before proceeding.
What does LOCKED mean on a GE microwave?
LOCKED means the control panel lock feature is active, which disables all touchpad inputs to prevent accidental or unauthorized use. It is not an error or fault code. The microwave hardware is functioning normally and no component has failed.
Why does my GE microwave keep showing LOCKED even after I clear it?
If the LOCKED display returns immediately after you clear it without anyone pressing any buttons, the touchpad membrane is likely sending a phantom long-press signal to the control board. Inspect the touchpad for visible warping, moisture, or damage. A replacement touchpad membrane or control board assembly is typically needed, with parts ranging from $30 to $150 depending on the model.
