KitchenAid wall oven F1E1 error code
F1E1 does not mean the same thing on every KitchenAid wall oven. Our data shows 2 documented meanings, depending on which engineering platform the model is built on. Look up your model number to see the one that applies.
| Meaning | Appliance | KitchenAid models |
|---|---|---|
| Oven power board (ACU) fault | Wall ovens | 38 |
| Upper oven sensor input uncalibrated | Wall ovens | 1 |
F1E1: Oven power board (ACU) fault
- Brand
- KitchenAid
- Appliance
- Wall oven
- Code
- F1E1
- Documented meaning
- Oven power board (ACU) fault
- Applies to
- 38 KitchenAid models on 2 platforms
- Can you keep using it?
- With caution
F1E1 means the oven's power control board (called the ACU or appliance manager) reported an internal fault, such as a relay or load driver not responding as commanded.
What the wall oven is detecting
The power board switches the bake, broil, convection, fan and lock loads and checks feedback from each driver. When feedback does not match the command, or it detects a short between board pins, it reports F1E1 (newer models add a number after a dash for the specific circuit).
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A relay or load driver on the power board that does not respond as commanded.
- Documented A short between board pins, which the documentation links to contamination on the circuit board.
- Possible An open circuit in a load (element, fan or latch motor) or its wiring, seen by the board as a driver fault.
Safe checks you can make
- Switch the oven off at the circuit breaker (or unplug it if the plug is easy to reach) for about one minute, restore power, and see whether the code comes back.
- Write down the full code exactly as shown (including any number after a dash) and when it appears; it speeds up diagnosis.
This stage requires professional testing. Full diagnosis involves hazards such as live line voltage, gas, a sealed refrigerant system or microwave high voltage. Do not attempt it yourself.
What a technician checks
- Reads the full code including any sub-number to identify the affected circuit.
- Checks the load and wiring on that circuit.
- This requires professional testing: the board switches line-voltage loads.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Wall oven control board replacement | $350–$830 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. The control may lock out some or all cooking functions. A power reset may clear the code for a while; if it keeps coming back, the control system needs diagnosis rather than repeated resets.

F1E1: Upper oven sensor input uncalibrated
- Brand
- KitchenAid
- Appliance
- Wall oven
- Code
- F1E1
- Documented meaning
- Upper oven sensor input uncalibrated
- Applies to
- 1 KitchenAid model on 1 platform
- Can you keep using it?
- With caution
F1E1 means the main control's measuring circuit for the upper (or only) oven temperature sensor has lost its calibration, so the control locks up.
What the wall oven is detecting
The control calibrates the input it uses to read the oven temperature sensor (RTD). If that calibration is lost, it stops heating and stores F1E1 within seconds.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A main control board whose upper sensor input lost calibration; the documentation points to the control, not the sensor.
Safe checks you can make
- Switch the oven off at the circuit breaker (or unplug it if the plug is easy to reach) for about one minute, restore power, and see whether the code comes back.
- Write down the full code exactly as shown (including any number after a dash) and when it appears; it speeds up diagnosis.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Confirms the code after a power reset.
- Checks for related sensor codes before suspecting the control.
- Replaces the main control when the fault persists.
Typical repairs and cost

Use with caution. The control may lock out some or all cooking functions. A power reset may clear the code for a while; if it keeps coming back, the control system needs diagnosis rather than repeated resets.

Repair or replace?
A fault code alone rarely justifies replacing a wall oven. Most F1E1 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 13–17-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
