KitchenAid Oven F6 E1 Error Code — What It Means
The F6 E1 code on a KitchenAid oven indicates a communication fault between the Appliance Manager Control and the temperature feedback system. On wall ovens, this involves the Appliance Manager Control, the Converter Control, and the wiring between them. On ranges, it points to the Appliance Manager or associated wiring. In practical terms, the control board is not receiving the expected temperature feedback, which can lead to runaway heating or inability to regulate oven temperature properly.
This is not a water or plumbing issue. It is an electrical fault in the oven’s control and sensing circuit. The oven may shut down to protect itself from overheating or may refuse to start a cycle.
Common Causes
- Failed oven temperature sensor (RTD sensor) The sensor probe that monitors cavity temperature has failed open, shorted, or drifted out of range, so the control board cannot read accurate feedback.
- Loose or damaged sensor wiring and connectors Corroded pins, loose harness connections, or heat-damaged wiring between the sensor and control boards interrupt the feedback signal.
- Appliance Manager Control board failure The main control board has a failed relay, damaged trace, or logic fault that prevents it from processing sensor data correctly.
- Converter Control failure (wall ovens) On wall oven models that use a separate Converter Control module, that board can fail and block communication with the Appliance Manager.
- Stuck relay on the control board A relay on the main board can weld closed or stick, creating a runaway condition that triggers the overheat protection fault.
Step-by-Step Fix
- Turn off power at the circuit breaker and wait one full minute, then restore power to see if the fault clears and whether it returns during the next cycle.
- Inspect all wiring harness connections at the oven temperature sensor probe (usually mounted in the rear wall of the cavity) and at each control board, looking for loose connectors, bent pins, corrosion, or heat discoloration.
- Test the oven temperature sensor with a multimeter set to measure resistance (ohms) at room temperature; a good sensor typically reads around 1,000 to 1,200 ohms, but consult your model’s service sheet for the exact specification.
- Replace the temperature sensor if the reading is open circuit, shorted (near zero ohms), or significantly outside the expected range, then test the oven through a full preheat cycle.
- Check the Appliance Manager Control board (and Converter Control on wall ovens) for visible damage, burnt relays, or swollen capacitors if the sensor tested good and wiring is intact.
- Replace the defective control board if sensor and wiring are confirmed good and the fault persists; the Appliance Manager is the most common board failure on ranges, and either the Appliance Manager or Converter Control may be at fault on wall ovens.
- Run a test cycle after any repair to verify the oven heats normally, holds setpoint temperature, and does not throw the F6 E1 code again.
Parts Often Needed
| Part | Notes |
|---|---|
| Oven temperature sensor (RTD sensor) | Amazon | Match the sensor type and connector to your exact KitchenAid model number; probe length and mounting bracket vary by oven design. |
| Appliance Manager Control board (main control board) | Amazon | The primary control board on ranges and wall ovens; verify your complete model and serial number for the correct board revision. |
| Converter Control board | Amazon | Wall oven models only; not present on ranges. Check your model’s wiring diagram to confirm your oven uses a separate Converter Control. |
When to Call a Pro
Call a qualified appliance repair technician if you are not comfortable working with live 240-volt circuits, if you cannot locate or access the temperature sensor and control boards, or if the fault returns after you have replaced the sensor and verified all wiring. Diagnosing control board failures often requires a wiring diagram and the ability to measure low-voltage signals between boards. If your oven is still under warranty or covered by a service plan, contact KitchenAid or your warranty provider before opening the unit, as DIY repairs can void coverage.
