Panasonic nn-sa651s was in use, and it stopped working while in use. Turned off completely.

To set the clock, press Timer/Clock twice when the microwave is not in use. The colon between the hour and minutes should start to blink. Type the current time (12-hour clock) with the appropriate number key pads. To save the time and exit the clock set mode, press Timer/Clock once more. Note: if you take too long to begin typing the time, the microwave may exit the time set mode. In that case, the colon will stop blinking. None of the other features of the microwave will work when the colon is blinking.

This is shown on page 11 of the manual which is available on the Panasonic NN-SA651S support page: http://shop.panasonic.com/support-only/NN-SA651S.html . The direct link to the manual is currently ftp://ftp.panasonic.com/microwaveoven/om/nn-sa631_nn-sa651_nn-sa661_en_om.pdf .

I hope this helps.

Press "Clock" or "Timer/Clock" again - colon stops flashing; time of day is set. You are now ready to use your new Panasonic Microwave Oven. When you first turn on yourmicrowave oven and under normal operation the "CHILD LOCK" feature is off. If "LOCK" or "CHILD" appears on your display . . .

It would be best to replace your microwave. The h98 code means there's an issue with a circuit. You can have it repaired but it would be cheaper to buy a new one

The microwave oven model NNSA651S was manufactured in a way that the oven light turns on only while cooking. - FT



Stupid design!!

Sometimes when the mag shorts it takes out the inverter. I would measure the mag leads to ground and they should be open or 20M or so. If you have both a mag and inverter bad it's probably time for a new oven.

It could be just the fuse and fixed for a couple bucks. Only way to know is open it up and check it. Eric

IS IT POWER UP.
please rmoove the cover and check the fuse also.
is it work?????

Sounds like the power inverter
