Microwave door will not open. the last time we used it, we heard a pop in the latch mechanism that sounded like a spring dislodging or breaking. How do I best open it up to inspect for a broken part?

SOURCE: Door latches will not close

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.

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 best place to order Panasonic parts is Tritronics. You can also call them at 866-779-5835.

What usually breaks is the door open lever, but it may be that the rear of the door open button and the face of the door open lever are worn to the point where they will not actuate.

On a counter top model, the outer cover will need to be removed to diagnose and repair this.

On an over-the-range model, only the control panel needs to be
removed in most cases.

Please unplug the oven first.

If you or someone you know wants to look into this, we have critical safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa.

Once it is apart, you'll be able to see how the door open button would press against the door open lever, which would then lift up against the door latch heads (hook-like projections on the door) and the door should open.

SOURCE: broken door latch on mod.nn-t945sfx

Do you mean the part with hook-like projections that stick out of the door, or the part that holds the door switches inside the oven?

If you need to replace the door latches (the hook-like devices in the door) you have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

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

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

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

In most cases, the spring mount on the inner door panel breaks off, and while the ideal way to fix it is to replace that whole panel, the time, cost and labor are considerable.

It's usually easier and cheaper and just as effective to use epoxy and some kind of hardware to fashion a new spring mount.

Or if there is enough material to drill a hole for the spring, do that, install the spring, then add a dab of epoxy to cover the bottom loop of the spring where it goes through the hole you drilled.

Let the epoxy dry overnight before you close the door or use the oven.

Sharp r520kst door won't stay shut

If the door will not stay closed it is the spring inside door, or the small plastic piece that holds the spring which is attached to the $80.00 piece called outer door.
To fix it, it is EASY and you do not have to even take the inside cover all the way off. Just remove the three sides of cover by gently slipping a plastic putty knife around rim to release the clips. Then attach the spring to the small hole below where the plastic piece used to be, which is located in the metal on the glass frame piece, use tweezers, hold the other end of spring as you place spring onto plastic door latch and set into place!
Snap the inside cover back on and YAY! FINI!

Hi dschema,

You have a door switch issue. There are three behind the panel. If you can lift and hold the door and it starts one of them is bad for sure. You would be better off replacing all three or have a repair man replace them because a microwave can hold 3000v even unplugged.

Hope it helps.

The spring attachment to the moving latch has broken off either replace the latch or drill a small hole in the latch body and attach some heavy steel wire to make a new attach point for the spring. the inside trim easily pops off and the latch just slides off.

Our panasonic inverter microwave (3 years old) needs repeated hard slams to shut the door so that the light goes off and the microwave will work. How do we fix this problem as I'm afraid we are going to...

We have a Panasonic Inverter microwave. Door became difficult to close and had to slam it hard while holding themicrowave to keep it from moving. When opening the door did not pop open but did unlatch. I ordered a new door lever from Panasonic. When got part I removed case from microwave and lever was okay. I then removed the perimeter strip on the inside of the door. With a screwdriver I stretched the spring at the bottom that keeps the door latches pulled downward. Spring still worked just not as stiff. Put perimeter piece back on the door and replaced housing (which I didn't need to remove in the first place), and then put a small drop of vegetable oil on the cams where the door latches hit when closing door. Viola, door opens and closed as new. Problem solved. Diagnosis: over time the latch tension spring hardens and gets too stiff. P.S.: I had several similar springs as backup in case I screwed up the original one.

Door latches to microwave broken

I assume you're talking about the spring that keeps tension on the door hooks (latch heads, as they're called by Sharp). When you shut the door, the "hooks" are held down by this spring to actuate the door switches. To fix this, you'll have to separate the door panels. You can download the service manual from my Web site. There's a loop built into the latch head assembly and sometimes the loop breaks. If so, you can drill a tiny hold in it and reattach the spring there. There may also be a loop on the innner door panel to hold the spring. That one can break, too. If it's broken, you'll have to find a way to secure the spring to the panel. If the panel material is thick enough, a tiny screw eye could be inserted, then epoxied overnight to secure it. I've attached a diagram to this message that should help you. If that doesn't help you, I have the service manual for the R1600-series microwaves on my Web site at: http://www.microwavedisplay.com/R1610.pdf Repost if you need more help.
