KitchenAid Oven Error Code F8-E3

F8-E3 means the oven detected an over-temperature condition while the door was closed but the latch was in the unlocked position. This is a safety fault most commonly triggered during or before a self-clean cycle when the door latch fails to engage properly. The control board cannot confirm the door is secured while the oven is at high temperature, so it shuts down and displays the code.

Resetting the oven by disconnecting power for a few minutes may temporarily clear the code, but the fault will return if the underlying problem is not fixed. If the latch motor, latch switch, or mechanical components are defective, the same conditions will trigger F8-E3 again as soon as the oven attempts a high-heat or self-clean cycle.

Repair costs vary depending on the failed component. A latch motor or latch assembly replacement typically ranges from $80 to $200 in parts, while individual switches are generally less expensive at $15 to $50. Adding professional labor, a typical repair visit can range from $150 to $400 depending on your location and the complexity of the repair.

You should not attempt to run a self-clean cycle or any high-heat function while this code is active. The fault indicates the door latch is not functioning correctly, which is a safety concern at elevated temperatures. Normal lower-temperature cooking may be possible after resetting, but the underlying latch problem should be diagnosed and repaired before running any cycle that requires the door to lock.

Start by inspecting the latch assembly, including the arm pivot joint, the arm-to-motor connection, and the plunger and hook springs, for any visible damage or binding. Next, measure the latch motor resistance, which should read approximately 2450 ohms. Test the latch switch and the door open/closed switch for proper continuity. Finally, check all power and element connections for looseness or corrosion. Replacing whichever component tests outside specification will typically resolve the fault.
