How to Troubleshoot Error F10 on a Kenmore Stove

Your Kenmore oven has a built-in fault detector. When the oven detects an issue, the display screen on the control panel will flash a fault code. The F10 fault code on your Kenmore oven indicates that the thermal protector on your oven's control unit, or microcontroller (MCU), has overheated. If the MCU overheats, the computer stops all motor functions. Several items on your oven could cause the thermal protector to overheat. Therefore, you must troubleshoot the F10 code to determine why it appeared on your display panel.

Step 1

Inspect the area around and behind the oven to ensure you did not place the oven next to a source of heat, such as a register vent or other appliance that becomes very hot. If this is the case, you must remove the oven from the heat source to prevent the issue from occurring again.

Step 2

Inspect the oven to ensure all vents on the oven are open and unblocked. This includes heat vents that vent to the outside of the home. Remove any clogs from the oven's venting and check to see if the code reappears.

Step 3

Inspect all of the wiring harnesses that connect to the MCU. Remove the back cover from the control panel with a screwdriver. Look for disconnected harnesses or any harnesses with black residue on them. This indicates an issue with the MCU. Remove the bolts that secure the MCU to the control panel housing and then replace the MCU with a new one. Reconnect all of the harnesses and retest.
