Affected model seriesTypical on JennAir wall oven / range; always confirm generation
Quick answer
Quick take: F02 ≈ oven control for many JennAir oven controls (model-dependent).
Model compatibility: JennAir reuses codes across series and model years, so F02 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: F02 is an oven control fault class on many Whirlpool-family ranges/ovens. One breaker reset; confirm exact text for your 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.
