KitchenAid Range Error Code F6 E1

F6 E1 indicates an over-temperature runaway condition detected during cook mode. The oven's control board determined that the cavity temperature exceeded safe limits without being able to regulate it back down. This is a safety fault that halts oven operation until the underlying cause is diagnosed and repaired.

No, you should not use the oven while this fault is active. The F6 E1 code indicates the oven may not be able to regulate its own temperature correctly, which creates a potential overheating hazard. Discontinue use until the fault has been properly diagnosed and the defective component has been repaired or replaced.

Repair costs vary depending on the root cause. A replacement oven temperature sensor is generally a lower-cost part, while a new control board is significantly more expensive. Total repair costs including labor typically range from around $150 to $500 or more, depending on the specific failed component, your location, and the service provider.

Some steps, such as inspecting wiring connections and checking the oven temperature sensor for visible damage, can be performed by a knowledgeable DIYer. However, diagnosing a stuck relay requires entering the service diagnostics mode, cycling individual relays, and measuring 120V AC at specific connector pins, which involves live voltage testing and is best handled by a qualified technician. Replacing a control board also requires careful handling of electronics.

Resetting the range by disconnecting power may temporarily clear the fault code, but the underlying problem will remain. If the faulty component, whether a stuck relay, defective sensor, or damaged wiring, is not addressed, the F6 E1 fault will return, often during the next cook cycle. A reset alone is not a repair.
