Oven door locked will not open

Self cleaning programs break things 80% of the time. You should never ever use that cycle. 650'F is too brutal to elements, fans, latches and circuit boards that are above the oven. I have never known one with a manual latch.

You need a new stove or a GE Technician service call.

Even parts seem hard to come by if that model number is correct.

My GE stove is 46 years old :>) The only part that doesn't work is the clock

..

Some ovens have a latch that must be locked for self-cleaning. Look at top of oven door and see if you have a sliding latch. Try to move it back to the left to unlock.

If a selfclean oven door lock fails to open after the self clean cycle and sufficient cooling time has elapsed (approximately 1 hour), there are several things you can try.

1. Unplug the unit or shut off the circuit breaker for 5 minutes. Plug the unit back in or turn on the circuit breaker. Set the clock and gently try moving the door lock lever (is so equipped) or opening the door.
   
   
2. Set the self-clean cycle again and only allow it to work for 15 minutes. Cancel the self-clean cycle and allow the oven to cool. Gently try moving the door lock lever (is so equipped) or opening the door.

If these procedures fail to correct the condition, the lock must usually be accessed and moved manually to open the door.
Most self cleaning ranges today use one of 3 different types of door locking systems. One design is solenoid driven, another is heat activated and the last, motorized.

• A solenoid controlled system can be identified by the lever that must be set to lock the door, plus a loud buzzing or clunking noise heard when locking or unlocking the door.
• The heat sensitive lock mechanism also has a locking lever but makes no noises. It instead utilizes a coiled spring to slowly lock the door as the oven heats.
• The motorized design has no lever to move, the motor locks the door by itself when the range is set for self clean. The motor may have made an audible whining or ratcheting sound when in use.

A motorized or heat sensitive style lock will usually be located beneath the cook top on free standing ranges. The cook top would usually need to be lifted to access the locking mechanism. On built in ovens, the oven must usually be removed from its enclosure (or at least partially) in order to remove the top panel to gain access to the locking mechanism. On some built in oven models, the lock assembly may be able to be accessed by removing the control console.
On the heat sensitive style (illustrated), there are no electrical parts used to operate the lock which could fail, so the whole mechanism will usually need to be replaced if not operational.
With the motorized lock mechanism, a volt/ohm meter is required to try to determine why the locking motor will not operate. The failure could be in the motor itself or the power supply leading to it, including a door activated and/or console mounted switch and switches on the latch mechanism itself.
On solenoid activated designs, the solenoid coil is a common failure point which is often mounted on the back of the range. On many of these models, the lock mechanism can be accessed by removing the rear panel of the appliance. Some models such as built-in ovens or drop-in/slide-in ranges, may have the mechanism mounted towards the front, under the top.
Failure of a solenoid style lock is most often caused by a bad solenoid. Once the lock is located, the solenoid coil can be checked for continuity. Some latch assemblies also have micro switches in the power supply that will need to be checked for faults too.
Be certain to unplug or remove power from the range before undertaking any repairs yourself and follow all standard safety precautions.
usually if you are unable to open it after all these tests then you would resort to manually opening the door by getting a piece of wire and slip it where the latch mechanism is and prying to the left this is a last means resort so try these other ways and get back to me with any further questions that you may have and please remember to rank how this opinion has helped in your appliance situation Thanks again

This is GE's trouble shooting advise:

Range - Oven Door Won't Unlock After Self Clean

The Oven Door has been Locked Accidentally:

• If no food or utensils are in oven, put it into a short self-clean cycle (1-2 hours).



• If there is food in the oven, let the oven cool to room temperature and try to unlatch the door.



• With electronic ranges there is a small chance that turning the circuit breaker off for a few minutes and turning it back on can release the door. latch to the "off"


Note: Do not force the latch at anytime!

Door Will Not Unlock After Cleaning:

On models with mechanical latches:

• Once the oven is cool after a self-clean cycle (approximately 30-90 minutes), slide the latch over to the left.(Some older models have a latch release button that must be pushed in while sliding the latch over.)

Note: Some models with oven Set and Temperature knobs must have those knobs set in the Clean position before the latch can be moved to the left. If your door won't unlock, try turning those knobs back to Clean, then slide the latch over.

If the above suggestions do not work try the following to unlock your door:

1. Disconnect power to range for 30 seconds.
2. Reconnect power and see if door will unlatch.
3. If door does not unlatch, and you do have food in the oven, wait for oven to cool completely and try again. If it still will not open you will need service.
4. If door does not unlatch, and you do not have food in the oven, set the oven up to clean for 1-2 hours.
5. Wait approximately 30 minutes and try to unlock the door.
6. If the door unlocks, the control has reset itself and there should not be any other problems.
7. If the door will not unlock or if you would like to schedule a service appointment, please contact GE Consumer Service at 1-800-432-2737 or schedule a service appointment on-line.

Note: Under no circumstances should you ever force the door or latch open.

Hi,

Yes you could clean it.

Check few details :-

t the bottom of this post you will find the web address for your ranges manual and the self clean system is in side this manual.

How to self clean
If your model has a door latch, never force the latch handle. Forcing the handle will damage the door lock mechanism.
The oven door must be closed and all controls set correctly for the cycle to work properly.
Before a Clean Cycle
For the first self-clean cycle, we recommend
venting your kitchen with an open window
or using a ventilation fan or hood.
Remove any broiler pan, broiler grid, all
cookware, probe and any aluminum foil
from the oven—they cannot withstand the
high cleaning temperatures.
NOTE:
If your oven is equipped with nickel oven
shelves, remove them before you begin
the self-clean cycle.
If your oven is equipped with gray
porcelain-coated oven shelves, they may
be left in the oven during the self-clean
cycle.
Soil on the front frame of the range and
outside the gasket on the door will need to
be cleaned by hand. Clean these areas with
hot water, soap-filled scouring pads or
cleansers such as Soft Scrub®. Rinse well
with clean water and dry.
Do not clean the gasket. The fiberglass
material of the oven door gasket cannot
withstand abrasion. It is essential for the
gasket to remain intact. If you notice it
becoming worn or frayed, replace it.
Wipe up any heavy spillovers on the oven
bottom.
Make sure the oven light bulb cover is in
place and the oven light is off.
IMPORTANT: The health of some birds
is extremely sensitive to the fumes given
off during the self-cleaning cycle of any
range. Move birds to another well ventilated
room.
NOTE: Use caution when opening the upper
oven after the self-clean cycle has ended.
The oven may still be hot.

How to Set the Upper Oven for Cleaning
On models with Gas/Control Lockout,
touch and hold the Gas/Control Lockout
pad for 3 seconds to turn it off.
NOTE: The surface burners must be turned
off prior to the self-clean start time.
If your model has a latch, latch the door.
Touch the Self Clean pad.
Using the number pads, enter the
desired clean time, if a time other than
4 hours is needed.
Clean cycle time is normally 4 hours. You can
change the clean time to any time between
3 hours and 5 hours, depending on how dirty
your oven is.
Touch the Start pad.
On models without a door latch, the door
locks automatically. The display will show
the clean time remaining. It will not be
possible to open the oven door until the
temperature drops below the lock
temperature and the LOCKED DOOR
light goes off.
The oven shuts off automatically when the
clean cycle is complete.
When the LOCKED DOOR light is off,
slide the latch handle to the left as far
as it will go and open the door. If your
range does not have a latch, the door
will unlock automatically.
The words LOCK DOOR will flash and
the oven control will signal if you set
the clean cycle and forget to close the
oven door or forget to latch the door
on models with a latch.
To stop a clean cycle, touch the Clear/Off
pad. When the LOCKED DOOR light goes
off, indicating the oven has cooled below
the locking temperature, unlatch the door
(on models with a latch) and open the door
The oven door must be closed and all controls set correctly for the cycle to work properly.

How to Delay the Start of Cleaning
Make sure the clock shows the correct time
of day.
On models with Gas/Control Lockout,
touch and hold the Gas/Control Lockout
pad for 3 seconds to turn it off.
NOTE: The surface burners must be turned
off prior to the self-clean start time.
If your model has a latch, latch
the door.
Touch the Self Clean pad.
Using the number pads, enter the
desired clean time.
Touch the Delay Start pad. The earliest
start time you can set will appear in the
display.
Using the number pads, enter the time
of day you want the clean cycle
to start.
Touch the Start pad.
On models without a door latch, the door
locks automatically. The display will show the
start time. It will not be possible to open the
oven door until the temperature drops below
the lock temperature and the LOCKED DOOR
light goes off.
The oven shuts off automatically when the
clean cycle is complete.
When the LOCKED DOOR light is off,
slide the latch handle to the left as far
as it will go and open the door. If your
range does not have a latch, the door
will unlock automatically.
The words LOCK DOOR will flash and the
oven control will signal if you set the clean
cycle and forget to close the oven door or
forget to latch the door on models with
a latch.
To stop a clean cycle, touch the Clear/Off
pad. When the LOCKED DOOR light goes
off, indicating the oven has cooled below
the locking temperature, unlatch the door
(on models with a latch) and open the door.


After a Clean Cycle
You may notice some white ash in the oven.
Wipe it up with a damp cloth after the
oven cools.
If white spots remain, remove them with a
soap-filled scouring pad and rinse thoroughly
with a vinegar and water mixture.
These deposits are usually a salt residue
that cannot be removed by the clean cycle.
If the oven is not clean after one clean cycle,
repeat the cycle.
You cannot set the oven for cooking until
the oven is cool enough for the door to
unlock.
While the oven is self-cleaning, you can
touch the Clock pad to display the time
of day. To return to the clean countdown,
touch the Cooking Time pad.
If the shelves become hard to slide, apply a
small amount of vegetable oil or cooking oil
to a paper towel and wipe the edges of the
oven shelves with the paper towel.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

The oven door lock needs approximately 1 hour to cool down before the oven door can be opened after a self cleaning cycle has finished. If the lock does not open after the oven has cooled down, you can try....1) Unplugging the range or shut off the circuit breaker for 5 minutes. Plug the range back in or turn on the circuit breaker.

If you've interrupted the clean cycle or have accidentally set the clean cycle with the oven door open, the latch may have engaged and now the door can't be closed because it will hit the latch. There may be a door activated* switch on the front face of the oven. In this case you may need to manually press that door switch with your finger while at the same time canceling the clean cycle to get the latch to retract so the door can close fully again.

try wiggling the door latch to get it open if not try the cleaning process, if that works, and see if the door comes unlatched and the light goes off. if not the lock light switch is stuck and it will need to be taken apart and cleaned

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