Ge monogram single convection wall oven

Just guessing but did you just use the clean cycle???? During clean, the oven temp gets high enough to trip the door lock safety thermostat. This is to keep owners from trying to open the door when oven is too hot from clean cycle. It sounds like that safety didn't reset to normal when it cooled off and therefore the door is still locked. With door locked you may need to get oven out of the wall and remove top cover to get to the lock system and thermostats. Make sure power is off before doing any of this.

Fan is bad or blades are bent hitting frame

you need to get a tech ,you cant correct this

It will remain locked until the temperature is safely as low as it should be. You just have to wait and be patient.

try unplugging oven.

We frequently see this symptom due to a failure in the electronic range control (ERC). We repair a lot of these.

try using a voltage stabiliser .it may just solve ur problem..

My oven was locked and would not open. No lock light was on but the oven was clearly locked. F9 error when I hit certain buttons.

Try this. I unplugged the oven for about 5 minutes. Plugged back in. A LOCK light came on. Held down "Oven Cancel" for a few seconds. Door opened and lock light went off. No more F9 error when I hit those buttons.

check the interlock switch, can be some object has stuck to it...
