Over temperature during clean mode (runaway temp).

First step from the service manual

Enter diagnostics mode, verify fault. In test mode, cycle bake/broil/convect relays to check element operation. Check voltage at P6-1 to P6-5 (120V expected).

What F6 E2 means on a KitchenAid range

The F6 E2 fault code on a KitchenAid range indicates an over-temperature condition detected during the self-clean cycle, specifically a runaway temperature event. During self-clean, the oven is designed to reach and maintain temperatures in the range of 800 to 900 degrees Fahrenheit to incinerate food residue. The control board continuously monitors the oven cavity temperature through the oven temperature sensor. When the sensed temperature climbs beyond the expected upper threshold and the control cannot regulate or halt the heating, it identifies the condition as a thermal runaway and triggers the F6 E2 code as a safety shutdown.

The primary systems involved are the oven temperature sensor (RTD probe), the electronic range control (ERC) board, and the bake, broil, and convection relay circuits. A stuck or shorted relay on the control board can cause one or more heating elements to remain energized regardless of the control signal, producing uncontrolled heat rise. Diagnosis begins by entering diagnostics mode to confirm the stored fault, then using test mode to individually cycle the bake, broil, and convection relays while monitoring element behavior. Voltage should be measured at connector P6, pins 1 through 5, with 120V expected at each leg when the corresponding relay is commanded on.

A faulty oven temperature sensor can also contribute by feeding the control board inaccurate temperature readings, causing the board to allow heating to continue past safe limits. Additionally, a failing control board that cannot properly interrupt relay output will produce the same runaway condition. Both wiring integrity and connector condition at the sensor and relay circuits should be inspected, as intermittent connections can cause erratic temperature readings that confuse the control logic during the high-stress environment of a self-clean cycle.

Common causes of F6 E2

  1. 01

    Stuck or shorted relay on control board

    Part replacement

    A relay on the electronic range control board can weld closed, keeping a heating element energized even when the control tries to shut it off. This is confirmed by measuring voltage at P6 pins 1 through 5 and checking whether elements de-energize when the relay is commanded off in test mode.

  2. 02

    Faulty oven temperature sensor

    Part replacement

    A defective RTD temperature sensor can send incorrect resistance readings to the control board, causing the board to underestimate oven temperature and allow heating to continue unchecked. The sensor's resistance should be checked and compared against the expected value for a given temperature.

  3. 03

    Failed electronic range control board

    Part replacement

    If the control board itself has failed and cannot process temperature data or interrupt relay output correctly, it may allow a thermal runaway condition even with a properly functioning sensor and elements. Cycling relays in test mode will help identify whether the board is responding to commands.

  4. 04

    Damaged wiring or loose connector at sensor circuit

    Wiring / connection

    Corroded, burned, or loose wiring connections between the temperature sensor and the control board can produce erratic or artificially low temperature readings, leading the board to keep heating beyond safe limits. Inspect all connectors in the sensor circuit, particularly at the control board connector.

  5. 05

    Bake or broil element short circuit

    Part replacement

    An internally shorted heating element can draw current outside of normal relay control, producing excessive heat that the control board cannot regulate. Visual inspection of the element for burn marks or breaks, combined with voltage checks at P6, can help identify this condition.

Frequently asked questions about F6 E2

What does F6 E2 mean on a KitchenAid range?
F6 E2 indicates an over-temperature runaway condition detected during the self-clean cycle. The oven's control system determined that the cavity temperature exceeded safe limits and could not be regulated, triggering a protective shutdown. The fault most commonly points to a stuck relay on the control board, a defective oven temperature sensor, or a wiring issue in the temperature sensing circuit.
Is it safe to use my KitchenAid range after an F6 E2 error?
You should not attempt to run the self-clean cycle again until the underlying cause has been diagnosed and repaired, as a thermal runaway condition presents a fire hazard. Limited use of surface burners may be possible, but operating the oven in bake or broil mode is not recommended until the relay and sensor circuits have been inspected and confirmed to be functioning correctly.
Will resetting the KitchenAid range clear the F6 E2 code?
Disconnecting power to the range will clear the active display of the fault code, but the underlying fault condition will remain. If the stuck relay, sensor failure, or wiring issue is not corrected, the fault will return the next time the oven heats up, and the same thermal runaway risk will be present. A proper repair is required, not just a reset.
How do I fix F6 E2 on a KitchenAid range?
Diagnosis starts by entering diagnostics mode to verify the stored fault, then using test mode to cycle the bake, broil, and convection relays individually while checking for 120V at connector P6 pins 1 through 5. If a relay is stuck on, the control board typically needs replacement. If relay operation is normal, the oven temperature sensor and its wiring should be tested next. A qualified technician should perform these checks given the high-voltage and high-temperature components involved.
How much does it cost to repair a KitchenAid range showing F6 E2?
Repair costs vary depending on the failed component. A replacement oven temperature sensor typically falls in the range of $20 to $60 for the part alone. A new electronic range control board is significantly more expensive, generally ranging from $150 to $400 or more depending on the model. Adding a technician's labor for diagnosis and installation will increase the total cost, usually bringing the full repair into the range of $200 to $600 depending on the root cause.
