Question about Panasonic NNSN797S Microwave Oven

1 Answer

Sometimes oven does not work. when ya hit start it just clicks - the screen looks normal for about 2seconds & then shows the clock time.

When ya hit start the oven just clicks for 2 seconds (no fan or heat). The display looks as if it was working for the 2 seconds and then returns to the clock display. opening & closing the door a few times seems to get it to work, but the same problem returns later.

Sounds like is 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.

That would be a bad upper interlock switch and charred connector. If so, see:

SOURCE: Door shut off malfunction

I have the same problem starting yesterday April 19. Have you gotten any answers.

SOURCE: Loud pop and now doesn't work

This is usually caused by either a bad door switch, a loose door switch mount (which are pretty simple problems to fix) or occasionally a problem on the control panel.

Door switch or mount trouble can be 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 you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

You can order Panasonic parts from Tritronics but if you only need a switch, you can order one from us for $5 postpaid.

SOURCE: Shuts off but everything else works

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.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

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

SOURCE: nothing works except the display

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.

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.

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.


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


If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

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

Setting the setting the clock


Colin,
Most of the time, you hit clock, then on the keypad, punch in the time of day and then either hit clock again or hit the start button. Some models may ask you for AM or PM but it will scroll a message if it is going to ask that & will tell you what button to push. Hope this helps!

Check the door latch switch inside the oven. The 4 switches where the door hooks latch on to when the door is closed has to engage with the door hooks to tell the oven that the door is closed. loosen the 2 phillip screws that holds the switch assembly and slide it to adj. and ensure that the switches close when the door is closed.
Sometimes the switches go bad and cannot make contact and must be replaced. If you see that the connectors on the switch is discolored or overheated replace the switch, it is bad.

The colon between the numbers on the clock, example 8:00 won't stop blinking even after I set the clock and hit the clock button again.


Sometimes the correct procedure for setting the clock is to press the CLOCK or TIME OF DAY button, then enter the time on the keyboard, then press the START button instead.

Otherwise, as long as you can enter a cooking time and your oven operates normally, then don't worry about it. On some models it is normal for the colon on the clock display to blink all the time.

Good luck.

Hi, my problem is with my GE advantium speedcook microwave oven. When using 'speedcook' feature, the oven starts, then there is sparking inside the circuit board area, followed by a loud POP, and this...


  • Select the "Options" menu and adjust the clock display settings if the display is blank. Set the clock if the oven won't start. The clock must be set for the oven to work properly, as oven programming is dependent on the clock.
  • Close the door tightly if the oven won't start. The oven won't start if the door isn't closed. You can identify from the lights whether the oven failing to start is related to the door or to the power supply. If the control panel is illuminated and interior lights are on when you open the oven door, you can be sure the oven is receiving power and any starting problems are due to the door not being closed tightly.
  • Press and hold the "Clear/Off" button if the oven performs strangely. Be sure to hold it for a few seconds. This will reset the GE Advantium.
    But as you mentioned that there is /was a loud noise this is a indication of the unit make any usual noise (groaning, gurgling, etc.?) or was / is it either louder or quieter than normal?It may be as simple as the top door switch or its mount or it may be a bad magnetron or shorted diode.

    Microwave starts as normal but cuts out after


    This is happening due to either the magnetron, or the Power Diode, or both, is breaking down, under load, then the unit detects the fault condition, & then, for safety reasons, to avoid a fire or explosion, shuts down the system. You need to take it in to be looked at please obtain a "Quote" before proceeding with any work. This way you can decide to repair or replace.
