Lock light does not come off

This is what I used on my Kitchenaid Superba maybe it will work on yours also.
Hold the "oven light"
then push the "CLEAN" button
and then the "START" button.
Wait until "Door Locked" shows on screen.
Press "Cancel/Off" (Upper Oven) wait until "Door Locked" turns off.
The oven F5 E1 is now fixed.

F90 Maximum oven door unlock time exceeded.
F91 Maximum oven door unlock attempts exceeded.
F92 Maximum oven door open time exceeded.
F93 Maximum oven door lock time exceeded.
F94 Maximum oven door lock attempts exceeded.


1. (F90, 91, 92, 93 & 94) Check the wiring between EOC & Lock Motor Micro Switch.

2. (F90, 91, 92, 93 & 94) Replace the Motor Door Latch assembly if necessary.

3. (F90, 91, 92, 93 & 94) Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor Cam.

4. (F90, 91, 92, 93 & 94) Check to see if Lock Motor Coil is open. If open, replace Lock Motor Assembly.

5. (F90, 91, 92, 93 & 94) Lock Motor continuously runs - if Micro Switch is open, replace Lock Motor Assembly.

6. (F92, 93 & 94) Check oven door Light Switch - if open, replace Switch.

7. If all situations above do not solve problem, replace EOC.


F90 is a door lock code, Try this...
unplug the range.
wait 1 minute.
turn the range back on,
then while holding in on the oven door.
start another self clean.
wait 2 minutes.
then cancel the self clean.

do not release the door until the door lock light goes out.

u tru unplugging the oven ?

this may be as simple as pushing in the door/light switch

1. select a clean cycle and start it

2. aftewr you press start, locate the oven light switch (should be somewhere that the door can hit is so light will turn on and off as you open and close the door) keeping the switch pushed in, press the cancel button to cancel the cleaning cycle. the door lock mechanism should then unlock

let me know how this does

My oven was locked and would not open. No lock light was on but the oven was clearly locked. F9 error when I hit certain buttons.

Try this. I unplugged the oven for about 5 minutes. Plugged back in. A LOCK light came on. Held down "Oven Cancel" for a few seconds. Door opened and lock light went off. No more F9 error when I hit those buttons.

Actually my son fixed it. The button on the face frame when the door is open, isn't just for the interior light. My son held it in and the oven latch slowly moved back to the open position. Thanks anyway

When I had a similar problem, the door wouldn't unlock even after unplugging, waiting 30 minutes, and plugging the oven back in. I finally had to manually unlock the oven by turning the lock latch motor myself.

Here's a good page that describes what the lock latch motor looks like and where it's located. Of course, there is 220V current running around inside there, so please unplug before removing the back access cover and put it back on before plugging the oven back in.

My symptoms:

• Oven failed to complete auto-clean cycle.
• Oven started beeping; control panel showed FSE 1
• About a minute after plugging in, oven started beeping and displaying FSE 1 again

Once I unlocked the door manually and plugged back in, the oven started behaving normally.
