What does the F9 error code mean on my Kenmore range Model 790.45794?

Model 790.45794. While cleaning the front I hit the "clean" and other buttons simultaneously. Door locked started blinking, door never locked,..pressed clear button caused "dr" code, pressed clear again and "f9" and beeping occurred. Press clear again and door locked keeps blinking but not locked. What should I do now? Seems like it just needs to reset. I have turned off the electricity.

The error code "F9" indicates a failure with the latch motor. Since the door did not physically lock, open the door and locate the door light switch plunger. Push and hold the door light plunger in and then press Clear/Off while continuing to press in on the door plunger. If "dr or F9" does not clear then shut the door and then program and start a clean cycle. Wait 2 minutes after starting the clean cycle and then press Clear/Off and wait to see what happens. If it continues to display "dr" or "F9" I recommend calling a service technician to diagnose and repair your range.

Likely failure condition;

Door motor failure/jammed. Latch motor switch failure.

Faulty main control board

Wiring problem.

Press CLEAR key.

If CLEAR key does not eliminate problem, turn off power for 30 seconds, and then turn on power.

Check wiring of Lock Motor, and Lock Switch A and Door Switch circuits. Look for stalled cooling fan, broken safety thermostat, shorts or opens.

Unplug P4, apply power (L1) directly to the Lock Motor, if the motor does not rotate, replace Lock Motor Assembly. Plug P4 back in.

NOTE: I do not recommend applying 120 volts directly to the lock motor unless you have electrical experience and you feel safe and confident in doing so otherwise I recommend calling a service technician to diagnose and repair your range.

Check Lock Switch A for proper operation (do they open and close, check with ohmmeter). The Lock Motor may be powered as in above step to open and close Lock Switch. If the Lock Switch is defective, replace Motor Lock Assembly.

If all above steps fail to correct situation, replace control.

NOTE: Disconnect the range from the power supply before accessing and checking the latch motor

. The latch motor is located behind the rear panel at the top center area.
