Jenn aire, After the cleaning cycle the door has remained locked.

This is an occasional problem for many brands. 1st, it depends whether you have a lever in front that locks the oven door or the door is locked electronically. If you have the lever, it is common for the lever to get bent too much to the right or left so that it does not (after while) come back to the full open position, yet it looks like it is fully in the open position. You will have to bend the outer part of the handle in order for it to travel the extra distance to fully release. Or you will need to lift the top (be careful if it is sealed burners;some sealed burners need to be removed before the top can be lifted or you will damage the burner tubes or the ignitor wires). You will then see a plate to the front of the range where the lock mechanism is located. Under this plate you will find the lock engsging pin or finger and posibly an electric selenoid coil ( basically a magnet coil that energizes the lock pin/finger). You must release this from the latch arm or latch hole on the oven door. This will get the door released and now you need to determine if the selenoid or the mechanism was at fault. There also may be a small switch that is turned on/off that is attached to the mechanism and this is the safety fail switch that sends the signal to the oven control to operate or not operate in clean mode. This switch could be stuck or internally fused in the on position. Hope you have the tenacity and skill to determine all this. Good Luck, Macgivor
