Quick answer
LOC · Control lock · JennAir oven — independent plain-language overview.
Model compatibility: JennAir reuses codes across series and model years, so LOC may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Homeowner summary: LOC usually means the control lock (panel lock) is active — not a failure. Hold the lock key per your manual (often 3 seconds) to unlock the panel. Never assume one forum post or generic chart overrides your rating-plate model. Independent technicians at JennAir Appliance Repair test the live appliance rather than guessing from the code alone.
