If you gently push up on the door latches (hook-like devices on the door) there should be spring tension. If they just flop right up, the spring is off.

Normally the problem is not the spring, but a broken spring mounting tab on the door latch head (hook) assembly or the inner door panel.

If it's the door panel, it's usually easier and cheaper to use epoxy and some kind of hardware to fashion a new spring mount.

The door latch head (hook) is easy to replace or repair if that's the issue.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

The best place to order Sharp parts is Tritronics.

We have critical safety & disassembly info at our site, linked here.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

The door no longer pops open when the latch button is pushed. How do I fix this?


One of the door latch arms or the latching mechanism inside the oven have broken. you may have to buy a complete door lock / latching assembly . Might not be worth it. Check with your nearest parts supplier.

Panasonic microwave oven model nn-h965bfx door wont close. feels like spring or something is no longer latching the door close.


I have the same model microwave. When I opened the thing up I noticed that the latch and safety switches are connected to the chasses with two screws. The problem with this design is the metal that holds the microwave together bends every single time you open the door over time this causes metal fatigue. The part that has to be replaced to fix this is the chasses itself. I have found a way to rig it up and work for a while. I don't know how long it will last, but it is working now. I used a little hole tape and a 1x2 piece of wood about 6" in length. Put the piece of wood on the side of the latch closest to the cooking section of the microwave. Then put the hole tape from the top lip to one screw in the latch. This seems to be keeping it from moving for now.

Can you move the latch in the door? This is spring loaded, maybe the spring is broken

Why does the light / safety switch stay on when the door latches shut ?


Most likely there is a part missing from the door latch mechanism that you need. This probably broke off when the handle failed. It would be a tab or wedge shaped piece of plastic that strikes the door switch and pushes the switch closed when the door is completely shut. You will need to find that piece and glue it back on or get a new handle assembly from Samsung.

You have a broken the door latch.Most people have the habit of slamming the door shut ( the same way some people hit the enter button on the computer ).With age the plastic becomes brittle and the slamming accelerates its demise. Now connected to this latch is a safety feature which shuts down the Microwave when the door is opened during cooking. So till you replace this latch the microwave will not work. Disconnect the microwave from the power outlet and remove the top cover ( 4 to 5 screws at the back ) , look near the bottom close to the DOOR OPEN button.You will see the rest of the latch with a spring attached to it.Do not attempt to glue the broken piece because the force exerted on the latch is very high and will not hold. You challenge is getting a replacement. Best would be to contact the seller or locate a authorized service center from where you might be able to procure it. It should cost you about 5$.

The panel push button that opens the door is not working. Doesn't seem to be connected to anything. Door won't open.


I suspect that the lower door latch has broken off. The lower hook is actuated by the push lever and in turn lifts the upper latch that of course is not being lifted.
Disconnect from the supply.
Remove the case from the microwave and you will see how the door latch actuator works. Lift it manually and you can open the door.
Do not try and use the appliance in that condition as it will take out its mains fuse as the door switches and latches for a safety interlock.
Hope this helps.

Remove the cover --- you shuld be able to release the lock from withinthe cabinet.

While you are there, you may want to replace the door safety interlock switch(s)

You may have to disassemble the door to get the latch fixed.

Directions to remove and open door panel to repair safety door latch.


You don't have to remove door to remove panel. Panel is held in by an outer plastic retainer which can be removed by carefully prying with a small screwdriver. I can be replaced by pushing it back in place after repair is completed. If you cannot open door from the outside, remove cover and you can see latches. Pry up on latch which will let door open.
