Quick answer
Quick take: HI ≈ high temperature for many JennAir refrigerator controls (model-dependent).
Model compatibility: JennAir reuses codes across series and model years, so HI 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
HI is a high-temperature alarm — a compartment exceeded its high limit. Confirm doors are sealed, reduce door-open time, and allow recovery before calling service. 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.
