Quick answer
JennAir oven code F3C: Oven sensor / clean. Confirm in the model guide.
Model compatibility: JennAir reuses codes across series and model years, so F3C 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
F3C relates to oven temperature-sensing or clean-mode temperature faults on some EOCs. Allow cool-down; never force a locked door. The same characters can map to different service actions across wall ovens, dishwashers, or refrigeration. Verify against your exact model docs. JennAir Appliance Repair provides independent diagnosis — not a manufacturer service agency.
