A lock sign is showing on the screen and the oven won't go on and I can't get the lock sign off!

Is there any letters that it is displaying on the LCD screen? If so it could be in lock mode or display mode.
Locate the "Cancel" and "Cook & Hold" buttons on the oven's control panel.
Hold down "Cancel" then hold "Cook & Hold" with another finger for three seconds. Both buttons must be held together.
Wait three seconds; the display will change from "OFF" to "LOCK" and the door will seal.
Repeat these instructions to unlock the door. The door lock cannot be activated if the oven is in use.

Dont Know

It thinks it's in clean mode.

Hi

The door lock assembly is bad and should be replaced, you can try to move it but that won't help and will have to be replaced to solve this issue. Hope this helps...please post back for further assistance.

If its a self cleaning oven it might be in clean mode. It usally takes 4 hours to clean. If its been more than 4 hours, it might be an electronic issue. Try unplugging it for about 5 minutes and plugging it back in.

This is telling you that the oven is locked. You will need to unlock it to use it.

this is either your sensor or your clock pcb. id remove the sensor some shops can ohm it out to make sure its bad

try unplugging the unit,
depending on your exact model it may just be lost in the programming becuse it sensed the door open while locking so it shuts down the lock for safety
just unplugging if for a few minutes might clear the error enough for the lock to rotate back to closed
position

the switch for the lock has an interlock to keep it from working when the door is open this may be shot

The red key sign is a lock against children. To cancel it you have to hold the two buttons at the same time for 5 seconds (you activate it the same way).

The STOP sign appears after the cooker switches of after a power cut. You just have to press the left button, and, using the right knob, set the time.
