Quick answer
Quick take: F1-9 ≈ oven control code for many JennAir oven controls (model-dependent).
Model compatibility: JennAir reuses codes across series and model years, so F1-9 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
F1-9 is an oven/range control fault on Whirlpool-family EOC hyphenated displays. It usually points to keypad, sensor, or control issues — do not force the door if a latch is involved. Confirm the exact sub-code for your JennAir model. Control generations share many JennAir / Whirlpool-family codes, but prompts and cleared-state behavior still vary. Cross-check the manual; book JennAir Appliance Repair if DIY resets do not hold.
