Yes, but the burned mark should be cleaned and if necessary sanded smooth and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Panasonic microwave convection oven model NN-CD997S works normal but stop heating

Judging from the model and without looking it up I expect that unit has an inverter. If it is not the Switches and you have replaced the mag, the inverter is the power supply for the mag to work so either mag not getting power from inverter or inverter not getting signals from main PCB Timer board.

Popping sound coming from my panasonic NNCD997S

The following works better if done in "low light".

Put a cup of water or small bowl in the unit, close the door and turn the microwave on.

If there is anything that you can see in the cooking area, there should be sparking and it is coming from something metal, even a small piece of aluminum foil that was left behind. The thing causing the sparking needs to be removed.

If you hear the noise and it is coming from inside the area of the microwave that you cannot see then you can:

1 - Take it to a repair shop.
2 - Depending upon the cost for repair, consider buying a replacement.

If the noise is inside the machine DO NOT CONTINUE TO USE IT. Get it FIXED OR REPLACED for your own safety.

Good Luck

Hi, I have a Panasonic Inverter microwave NN-Sn9688. It's less than a year old and when you press the START button H98 appears and it will not start. Everything else works, clock etc and reset/stop...

Hi Judith, I am Kelly

If this has a 1 year warranty it is time to make that call.

Otherwise see this link about H97 or H98 codes:

There are a few things that can cause the problem, none of them cheap repairs. The Magnetron filament, Control board and Inverter are the top 3 other than a losse connection.

I tried running the Model number NN-SN9688 and it does not cross. See Panasonic link here:

I did not go to Panasonic Global and try other countries. I just did a USA search.

Thanks for choosing FixYa.

My daughter put metal in oven it shut off. the oven turns buts shuts off after a few seconds. help

metal cannot absorb the microwaves, the microwaves bounce around inside the oven. Eventually they reflect back to the magnetron, which is the part that produces the microwaves. The magnetron can overheat and be damaged.

the main control board is "seeingf" a high amprage draw from the inverter board . you have a problem with the inverter or the magntron . parts are more than a new unit . try to stay away from the inverter type , there just not ready for prime time . google "panasonic inverter reviews " and you will see just common your problem is good luck
