Jenn-Air ovens use the Whirlpool F#-E# code format, where the F number is the fault category and the E number the specific failure. The common ones are F2-E0 (stuck key), F3-E0 (oven sensor), and F5 codes (door lock on self-clean).
As part of the Whirlpool family, Jenn-Air uses one of the more diagnostic-friendly code schemes. F1 codes generally point to the control board or its memory, F2 codes to the user interface (a stuck or shorted key), F3 codes to the oven temperature sensor, and F5 codes to the door-lock circuit during self-clean. Reading both digits narrows the fault to a specific circuit.
F2-E0, a stuck key, is common: the control reads a button as continuously pressed, sometimes after a spill on the panel. Wiping the panel and letting it reset occasionally clears it, but if it returns the keypad ribbon or control has failed. F3-E0 points to the oven sensor reading out of range, a straightforward sensor replacement and recalibration.
F5 door-lock faults appear during or after self-clean, when the heat stresses the lock motor and switch. Because Jenn-Air rides the Whirlpool parts platform, components for keypads, sensors, and lock assemblies are widely available and repairs are quick. We read the code, confirm the circuit with a meter, and replace the failed part.
