Direct answer
On the covered JennAir wall oven, Locked, Lock or Loc means JennAir documents this display without stating a cause for it. Treat any cause you find elsewhere as unverified. First, reset power to the product: Power unit down by turning off the circuit breaker(s) for one (1) minute, then power the unit up by turning the circuit breaker(s) on.
Definition versus diagnosis
The display names a detected condition—not an automatically failed part.
What this covers
- JennAir wall oven covered by the cited source
- Displayed code or documented alias: Locked, Lock or Loc
- The exact operating state described by the manufacturer
What it does not cover
- ×Another product type or original-manufacturer platform
- ×A visually similar but different code
- ×Internal live electrical, sealed-system, gas, battery-cell or control-board repair
Match every character and the exact product
ReversiblePhotograph the complete display and product label. This record covers Locked, Lock or Loc on JennAir wall ovens and combination wall ovens with electronic controls. Code availability varies by model and by whether the oven is electric, gas or a combination unit. This is a cooking appliance: if you smell gas, do not operate any switch — leave and call the gas supplier from outside.
Preserve the failure state
ReversibleReset power to the product: Power unit down by turning off the circuit breaker(s) for one (1) minute, then power the unit up by turning the circuit breaker(s) on. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversibleReset power as JennAir directs; arrange service if the code returns. JennAir documents one check for this code — unlock the Oven Control and Oven Door — so confirm that before treating anything else as the cause.
Verify once, then respect the service boundary
ReversibleRepeat only the shortest safe action that reaches the original stage. JennAir specifies a 1 minute power interruption for this code, not an arbitrary one. If Locked, Lock or Loc returns, stop repeated resets and use model-specific manufacturer support.

What does Locked, Lock or Loc mean on a JennAir wall oven?+
JennAir documents this display without stating a cause for it. Treat any cause you find elsewhere as unverified.

A reset may hide the display temporarily but does not correct the documented fault. Record the code and complete only the safe checks first.
Why is the complete model number required?+
Manufacturers reuse characters across platforms. The model number determines which official table, controls and service boundary apply.
When should I stop?+
Stop for smoke, arcing, burning odor, uncontrolled water, gas odor, battery swelling, extreme heat or any condition the manufacturer directs to professional service.
