Whirlpool Oven Error F9: Power or Element Failure

The Logic Verdict

My Take: F9 is officially a “Door Latch” or “Voltage” error. But if this happened immediately after a power outage or surge, don’t buy a new control board yet. As the video demonstrates, a shorted or open Bake Element can trick the computer into throwing an F9 code. Test the element first—it’s much cheaper than a board or latch assembly.

What It Means

F9 = Door Latch or Voltage Mismatch. The oven control detects that the door latch is in the wrong position, or the voltage supply is unstable.

Potential Causes

1. Failed Bake Element: (Most common after power outage) An open circuit in the element confuses the voltage sensing logic.
2. Door Latch Failure: The motorized lock assembly is stuck or broken.
3. Voltage Issue: The outlet is not providing proper 240V power (check your breaker).
4. Control Board: If all else fails, the board itself may be fried.

Step-by-Step Troubleshooting

1. Hard Reset: Flip the breaker off for 5 minutes. Turn it back on.
2. Test the Bake Element:
   • Unplug the oven.
   • Remove the rear panel to access the element terminals (or remove from inside).
   • Test for continuity with a multimeter. If it reads “OL” (Open Line), the element is dead.
   • Replace the element if bad.
3. Check Voltage: Ensure the outlet is providing 240V across the two hot legs.
4. Inspect Door Latch: If the element is good, check the door latch switches for continuity.
