Quick answer
F3H1 — Oven high-limit on a JennAir oven (verify for your model).
Model compatibility: JennAir reuses codes across series and model years, so F3H1 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
What owners usually need to know: F3H1 points to a high-limit / over-temperature related oven fault on some platforms. Disconnect power if unsafe heat is present and book service. Wording and recovery steps differ by JennAir model and control generation — confirm in your use & care guide or Product Help.
