Usually Kenmore model numbers will start with a three digit prefix then have a decimal point after it. Like(NNN) NNN-NNNNor 790.84749549. It is very important to have the first three number prefix before the decimal point as for those numbers will tell us who has actually made the machine. Kenmore is just a brand name by Sears. they actually dont make their appliances
, other bigger more well known companies like GE, LG, Whirlpool and so on.
Please first try to locate the model number on the machine or in the paperwork you have with the machine. If you can't locate the model and the door is still locked then dont worry about it for now.
Please power off the machine by flipping off the circuit breaker to the unit for at least ten minutes. Then after the ten minutes turn it back on and tell me what the control says? If the locked door goes away, great. Try to open the door. If the door still doesn't open then try to put the oven back into a self clean cycle and try to look and hear for the door lock to engage and disengage.
I know it will be hard to see, but look towards the top middle portion of the door where the door lock and latch is located and try to see if the door lock engages and locks or if it stays locked. Or if the door lock disengages and unlocks try to pull the door open. Now here you will need to time it so that when you pull the door open it is when the door is unlocking.
If you get the door open awesome. Just cancel the clean cycle and let the oven sit unused for about two hours if you can. If the door still doesn't come unlocked then let me know.
The only other chance you have of getting the door unlocked again is to manually force the door open with either a thin putty knife or butter knife. Taking the knife to the door lock and forcing it to the unlock position.
If the door will not unlock still then you will need to change the door lock assembly and possibly even the main control board.
Please try those suggestions and let me know what happens and I will help you more.
