Question about Microwave Ovens

2 Answers

I have a Panasonic 1250w microwave and the door won't close and latch and when it does the light stays on then once you do finally shut it and press start, the timer starts but microwave does not turn on! This is the SECOND microwave with the exact same problem! First one did it after a year this new one is 6 months old and started after 2 months and got worse and worse until now it won't close or start unless you try several times until it finally closes and starts but takes MANY tries to do it! Taking it back but am expecting the same thing from this model once replaced AGAIN!!!

Sounds like an alignment problem with the door itself and/or the interlock switches which operate as the door is opened/closed. Recommend a factory authorized service center. You don't want to take the chance of a leaky door.

The problem is an engineering defect. The mechanism that engages the door latch is mounted to a steel plate that is "L" shaped and when you close the door it pushes against and bends this plate out of position. After a while the metal plate fatigues and stays bend out of position and the door stops engaging and locking so the two safety switches inside don't get depressed. Result door won't lock and light stays on. I had to re-engineer it by cutting the tube of a pen to size and placing it in as a support bracket to put pressure on the plate so it won't bend anymore. My wife was going to throw it in the trash. Note of caution: I did cut my hand in several places trying to get the bottom cover on and off the microwave as the metal edges are razor sharp!!! I love this microwave it is my second one.

SOURCE: Sharp Carousel Microwave door latch stopped working door won't stay closed

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: http://tinyurl.com/yzjozk

We also have this full service manual at our site: http://www.microwavedisplay.com/R1480_R1481_R1482_sm.pdf

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.

SOURCE: Microwave auto-starts when door is closed

the buttons recently stopped working sporadically and now everytime I open the door, the unit turns on. The only solution was unplugging.. Is there a fix short of replacing it?

SOURCE: Panasonic Sensor 1250W Microwave cycles off after only 5 seconds.

See if this describes what's happening:

  • Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector.
If so, see http://www.microwavedisplay.com/safety.txt , http://www.microwavedisplay.com/disassembly.txt and http://www.microwavedisplay.com/doorsw.txt

Otherwise, 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.

That 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.

Common problem. Apply a small dab of lithium grease to the tips of the door hooks. You might also have to adt. the door latch switch assembly inside the oven as it could be bent out of shape from the hard to close door.

Microwave won't start


I have the same problem. Is the light still on inside the microwave? Mine is on and the microwave thinks the door is not shut. I took the top off of the microwave and the latch needs to push down on a switch once shut. The latch was reaching the switch, but I think some spring in the door, pushing the latches down, has broken since it reaches the switch when closed but there isn't any downward force to flip the switch.
I am trying to figure out how to repair the latch but if your light is on when you "shut" the door, you may have the same problem.

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.

Hi I have a new Kenmore microwave model 721.8503 - it is a month old and wont turn on.. I close the door and the light stays on and it wont work..the door is completely shut


It sounds like the light switch isn't being deactivated which is preventing the microwave from operating (a failsafe).
Look to see that the buttons inside the microwave (where the latches are inserted when you close the door) are actually being pressed.
They may be out of place, obstructed, or your latches on the door may be damaged.
If you don't see anything wrong, try pressing the buttons yourself (with a pen bottom) to see if the light goes off.

I cannot open the door of my Panasonic NN-T543W microwave


Well do not pry the door open since there is an easier remedy which will lead you in the direction that you need to fix your problem. Take the cover off after you disconnect the power to it. Once you have taken the cover off (only a few screws) you will be able to see the two latches that hold the door closed and the link that opens both of them. You can just lift both latches at the same time and it will open. After you have done that take a good look and press in on the open door button and you will see where you have the problem of the door hanging. That button should push a linkage that pushes up on both latches at once to open the door. It is spring loaded so that it comes back down so that when you close the door it will hold the door closed. Anyway that is where your problem is. Let me know if you need more hlep.

Door does not secure when closed


Hi , Either you have a faulty door interlock switch(es), or the door latches (on the door) have been damaged and will not activate the interlocks. either way, you have to be conversant with adjusting microwave latch assemblies once the repair has been effected AND THE USE OF AN OVEN LEAK DETECTOR IS IMPERATIVE for final testing or the end user will be subjected to harmful levels of microwave radiation.
