Oddly enough, the switch holder is called a "door hook". For this model, it is part # F3020-1200 in case that is bad.

The hook assembly that protrudes from the door is called the "door key".

If you gently push up on the door key there should be spring tension. If it just flop right up, the spring is off inside.

Normally the problem is not the spring, but a broken spring mounting tab on the door key 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 key is easy to replace or repair if that's the issue.

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 best place to order parts for this brand is Tritronics. Or you can call them toll-free at 866-779-5835. Their Web site will be down until Jan. 2nd.

Door release buton does not open the door


You can disassemble the microwave oven and check out the release mechanism. You'll find several hooks that hold the door closed and a linkage mechanism to the door opening button. There may be a broken piece of plastic or maybe just a loose or missing screw that holds linkage together. In the case of a broken plastic part, you can fix it with a 2-part epoxy adhesive, but you'll need to permanently splint across the break with a piece of metal or strong plastic that you've scavenged from somewhere. Before epoxying the splint in place, rough up all plastic surfaces where you want the epoxy to stick well.
Good luck.

I have a Panasonic Inverter Model NN-T664.It acts


This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.


Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

If you only need a switch, you can order a universal type here for $5 postpaid.

I have a Panasonic NN-S961 microwave. It turns on when I open the door. When the door is closed it turns off. Otherwise it opperates normally.

Sounds like the door switches are out of adjustment or broken.
I would take it to a shop for repair. Microwaves are almost always repaired affordably unless it is really old.
Hope ya fix it!
