What Lock means

On JennAir electric radiant and touch-control cooktops, Lock means Control Lock is active. It prevents unintended use of the cooking areas. If Control Lock is activated while the cooktop power is off, the cooktop is locked out and the elements cannot be turned on from the touch controls. If it is activated while power is on, all keypads are locked except Power and Off.

Common causes of Lock

  • Control Lock turned on deliberately or by accident
  • Panel touched while cleaning
  • Pet or child pressing the lock key
✓ One safe check you can try

1. Find the Control Lock key on the touch panel. 2. Touch and hold it as your cooktop directions show until the Lock message disappears. 3. Try an element. 4. If Lock will not turn off, wipe and dry the panel, switch the breaker off for a minute and back on, and try once more. If it stays locked, call us.

! Why to stop there
  • A panel that will not unlock may have a failing key.
  • Pressing many keys can add to the confusion.
  • Moisture on the panel can make a key read as held.
  • We check the panel and quote in writing.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

LockLock questions
Is Lock a defect?

No. It is a safety feature that prevents unintended use of the cooking areas. Unlocking it restores normal use of the cooktop right away, with nothing to repair.

Why can't I turn on an element?

If Lock is active with the power off, the cooking areas cannot be turned on from the touch controls. Unlock the cooktop first, then try again.

The lock key does nothing. What now?

Clean and dry the panel and cycle the breaker. If the cooktop still will not unlock, call us. We quote the repair in writing first.
