    I'm having the same problem. It's simply the microwave door that has the word, 'Inverter' printed on it. The hooks that catch into the main body lost their spring load. Is there a way to access these hooks in the door?

    the black plastic piece that closes the door broke off, and now the microwve won't work

  • Anonymous Aug 04, 2008

    Just had the same problem with mine (no tension in door latch, door would not shut, light stayed on). Followed the instructions below (took off plastic frame on which the door latch sits), and saw that the spring had fallen off. Upon closer inspection, the plastic hook attached to the frame of the microwave on which one end of the spring was held had broken off. So took a small piece of wire, looped it through one end of the spring, and then tied the wire around the little protrusions in the frame. Hooked the other end of the spring back to the door latch, and now it works great! Thanks for saving me the cost of a new microwave!

    Same problem. I drilled a small hole in the plastic where the piece was that held the spring. The I tied the spring to it with thin metal wire. It works great.

Thanks for the tips - here is what I did (my wife calls me the Canadian McGuyver!) After taking off the plastic frame (using instructions in Solutions noted above) I used the metal part of a key ring and hooked one end to the spring and looped it around the thick finger/protrusion at the bottom.

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.

The best way to test the door latch is to lift it up, there should be spring pressure trying to pull it down, if there isn't the spring is more than likely the problem. With mine the hook on the door frame broke. It was ok on the latch. Instead of replacing the door part I shortened the spring then attached to a square hole in of the teeth below the latch making sure it had enough tension to pull the latch down fully with no play. to get to get to it the out the inner panel of the door must be removed by gently starting at the bottom of the door working the panel loose. the only thing holding it in is a series of teeth around the inside. to re-install it just align it and push it back into place.

Need to order the latch assy' or try to repair it from the inside latch , there is a good reason why it felt, there must be a clip broken off, check to see if the plastic part has a tab broken off of a clip if soo replace it first,

Hope this help

I have Panasonic NN-SN69605 stainless-steel microwave oven. Date of manufacture date is April 2012. I don't think I've owned it more than 18 months. I had to slam it before the latch would "catch". Quite annoying. So I sprayed a contact cleaner and lubricant in and around the door hooks and worked them up and down. The action got a lot smoother. I realized the the most problem might be gunk on the springs. Normal use would not cause such a problem. Those door hook holes are large and invites all kinds of trouble from hearing and reheating our culinary delights. No longer a problem.

Panasonic 1250w genius senor inverter less then a year old. Control panel lights up, works.microwave itself does not, control panel shuts off in a few seconds


When a Panasonic Inverter Microwave shuts off after a feew seconds, it is either a bad inverter which is the quite expensive circuit board that powers the magnetron that puts out the microwave energy, or a bad magnetron, Or BOTH typically this would be a costly repair, But since it is still under warranty. You need to find a Panasonic warranty service provider in your area. If it is a counter top unit, you may have to take it to them for repair.

Panasoni microwave NN-H965WF fan stays on when door closed


Because Panasonic use an inverter system to generate microwave energy the machine has to cool itself down at a steady rate and this is generally the reason the fan stays on when the door is closed,hope this helps

When you close the door the turntable comes on? Almost all have a safety switch in the side of the wall where the door closes, An inspection inside the unit will show if switch is damaged or out of position which could cause this problem.

Panasonic 1200 watt microwave shuts down in 10-15 seconds


Check the door switches to make sure they are not faulty, otherwise it may be the inverter.

IS the microwave in a cavity? If so, you need to have at least 15cm (6in) space above the microwave, 10cm (4in) behind the microwave, and 5cm (2in) on either side, as the latest Inverter microwaves run very hot and need a lot of ventilation.

Shuts off after approx 5 - 7 sec. some smoke


If it stops after 7 seconds, it has a problem with the inverter.

If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

You can find an authorized Panasonic servicer here.
