Microwave displays E11 and will not start; clock and display otherwise appear normal.

Safety Warning: This is typically a low-risk control issue, but always unplug the unit before removing any panels.

Steps:

• Check your Insignia user manual for the Control Lock or Child Lock feature. Commonly, holding a specific key (e.g., STOP/CANCEL or a LOCK icon) for 3–5 seconds toggles the lock.
• Press and hold the indicated key to disable the lock and see if E11 clears.
• Wipe the keypad with a dry cloth to remove moisture or residue that may cause a key to appear pressed.
• Unplug the microwave for 5 minutes, then plug back in and test.

If E11 persists:

• The control may be detecting a stuck key. The touchpad membrane or control board may need replacement.
• Have a technician test the keypad matrix and replace the control panel assembly if necessary.
