Microwave shows E11 and beeps; child lock may not function correctly

SAFETY: No internal high-voltage work is required for this check, but unplug before removing the control panel.

E11 is related to the keypad lock/child lock circuitry.

• Step 1 – Try manual child lock toggle:
  • Refer to the SilverCrest user manual for the specific key combination (often holding the STOP/CANCEL or a padlock symbol key for 3–5 seconds).
  • Toggle the lock on and off several times.
• Step 2 – Power cycle:
  • Unplug for 5–10 minutes, then reconnect and test.
• Step 3 – Clean keypad:
  • Wipe the keypad with a slightly damp cloth and mild detergent; dry thoroughly.
• Step 4 – Inspect keypad ribbon (unplugged):
  • Remove the control panel and reseat the keypad ribbon cable.

If E11 persists, the keypad or control PCB may need replacement.
