May I have the full model # of your oven?
Also its age and if you used a self clean cycle just prior to this problem?
Thank you for that information.
Please try one thing for me?
Turn off power to your cooker at the mains for 10 full minutes unless its still hot. In that case you would need to leave the switch off at the mains until its completely cool. Then you can switch it back on. Let me know if this unlocks the over door or not?
Also how old is your oven?
Sounds good, I'll be here ;-)
