OPened the oven door then accidently started the cleaning cycle? Unable to close the door.

You need to read the oven manual on how to start the self-cleaning cycle. You cannot use an oven cleaner like Easyoff as it can destroy the surface that's meant to be self cleaning. The oven door will lock during the cycle and during the cool down, so it can't be opened during the cleaning cycle.

Leave the door open and do not force the lock mechanism..cancel the clean cycle and the lock unit should cycle itself to unlock but it will take time.

Your user manual above.

Open the door find the door switch hold it in while turning the oven into clean allow it to start the clean cycle then cancel the clean cycle and don't release the door switch until the latch stops

It is probably the self-cleaning latch that keeps the door from being opened during the self-cleaning cycle. Looks like it didn't retract all the way. Did you use the self-cleaning cycle? . Do this: Quiet the house down, open the door slightly and close it, letting it hit the obstruction. Do this again and again. You don't have to close it hard at all; in fact, do it gently. By listening, you will be able to hone in what is keeping it opened. Then go from there.

you might try the following, although it is the instructions for an old model, it may be relevant;

"The actual self-cleaning process is initiated by a simple 5 step procedure: 1. Set the range clock to time of day. Note: on models not equipped with an automatic oven timer, the self-cleaning cycle is preprogrammed for a 21/2 hour cycle. Use Steps 3, 4 and 5 only. 2.Establish the length of cleaning time by:
A. Setting the start time. Press and turn the start dial of the automatic oven timer clockwise to the desired starting time. B. Set the stop time. Press and turn the stop dial of the automatic oven timer clockwise to the desired stop time. Max time is 3 hours miniumum 1/12 hours. 3. Set the oven selector dial on the control panel to "Clean" 4. Set the temperature control dial to "off". If you temperature control dial has a "Clean" position, then set the dial to "Clean" instead of "Off". 5. Remove oven racks, broiler pan and broiler grid from lower oven. Close and lock the oven door by moving the latch lever as far right as it will go - into the locked position. If the lever is accidently dislodged restore it to the locked position. Otherwise, the self-cleaning process will not take place. Shortly after the cleaning cycle has begun, the oven temperatur reaches a degree in excess of the normal broiling temperature. The red "Clean" light will come on and the clean cycle will start. In a few minutes the door lock lever, which you have placed in the locked position, will automatically be secured to prevent the oven door from beging opened during the cleaning cycle. This latch remains locked until the clean cycle is complete and the oven temperature reduces to normal baking and broiling temperaturs. NOTE: Prior to self cleaning cycle operation, the oven and surface lights must be turned offed. The upper oven can be used."

try unplugging oven.

unplug the stove, then force the mechanism back with a screwdriver

Thanks a million, solved the problem like a charm. For those that can't find it, it is on the left side orf the OVEN, not the stove. Once you open the door, you'll find it on the frame's upper left side corner, can't miss it. Good luck
