We service the full Jenn-Air lineup, and most calls trace to a handful of parts. Below is how those faults show up in local kitchens and how we diagnose them.

Whirlpool-Platform Codes
Jenn-Air cooking and refrigeration are built on the Whirlpool platform, which means they report the familiar F#-E# fault codes, where the F number names the function and the E number names the specific fault. That two-part structure is more precise than a single code, because F2-E0, for example, points straight at an over-temperature condition rather than a general oven fault. Knowing how to read the pair speeds up every diagnosis on these units.
Common Code Pairs
The pairs below are the ones we meet most on Jenn-Air ovens and cooktops. Each points to a specific circuit we confirm with a meter before replacing anything.
| Code | What It Means | What We Check |
|---|---|---|
F2-E0 | Oven over-temperature | Temperature sensor and relay board |
F1-E0 / F1-E1 | Control board fault | Control board and connections |
F5-E0 | Door lock fault | Lock motor and switch |
