Panasonic Genius Premier microwave - I was painting, etc in the kitchen so I unplugged it and when I plugged it back in the next day it does not microwave. The light comes on, the clock works once I set it, but the turntable does not turn and there is no cooking. I've looked for a reset button but didn't find one. What am I missing? It has been working beautifully til now.

A P-error-countdown on a Panasonic Genius microwave can be caused by a number of issues.
First, try unplugging the microwave for a few minutes and then plugging it back in. This can often clear any temporary error codes and restore the microwave to normal operation.
If the problem persists, check to make sure the door is closing properly and securely. A damaged or misaligned door can cause the microwave to think that it is open and prevent it from working.
The issue could also be caused by a problem with the microwave's control panel. Try to reset the microwave by unplugging it for a few minutes and then plugging it back in.
If the issue continues, it is likely that there is a malfunction with the microwave's control board or other internal component. It's best to contact the manufacturer for assistance or take it to an authorized service center for repair.
It's important to never try to repair a microwave oven by yourself as it can be dangerous and may cause damage to the appliance or even injury.

Here's your answer and then some, in case it helps

Brand: Panasonic
Name: The Genius Premier 1000W
Primary feature: reheating of popular food categories is done automatically (time and power level automatically determined, often time adjusted based on steam sensor). Defrosting also done by entering weight (so time is automatically determined).
Color: black matte top/lateral sides; black gloss front; white back; silver bottom
Style: Counter/table top (label says not for mounting)
Model: NN-S7768A
Manufacture Month/Year: September/1996

Dimensions Exterior: 14"T x 23-3/8"W x 16-1/2D (18 including protruding door handle and back cord plastic clip)
Dimensions Interior: 10-5/8"T x 16-1/4"W x 15-1/4"D
Cubic Feet interior: ~18.28 cu ft (based on three interior dimensions multiplied together and divided by 144 to get from cubic inches to cubic feet)

Note:
I found a manual from a similar model; you'll probably want to pring page 15 as a reference, since each food category button has 2-4 modes based on the type/temperature of the food, e.g. veggies are 1. for potatoes up to a certain quantity and weight each, 2. fresh veggetables of a certain weight, and 3. frozen vegetables of a certain weight. Specific instructions on adding water, covering, etc. are also included. Makes microwaving pretty easy!

Before spend $$ on replacement boards, make sure anything attached to it is powered off. Unplug TV for 5mn to 15min. Plug back in and it should power on. If not leave unplugged overnight before spending on a replacement board. We have to do this 2-3 times per year when someone forgets to turn off auxiliary components (receiver, DVD, cable box, etc) first. It has always come back on.

RESET THE SYSTEM BY UNPLUGING THE MICROWAVE CORD FROM POWER FOR 30 SECONDS, CONNECT BACK TO POWER IF THE MICROWAVE CONTINUE WITH THE PROBLEM MAY HAVE A BAD CONTROL BOARD OR BAD ELECTRONIC CONTROL PAD...

That fault is a little tricky. Need to check if you are getting voltage onto primary of transformer. If you are, the problem is almost certainly the magnatron which has gone open circuit. If and when you replace it, change the cap and HVdiode. Wont be sorry if you do. If no voltage there , your board is faulty. replace it.

try unplugging it for 10 minutes. Otherwise, try looking at the instructions:

hi there. i can help you. the answer is 1475 watts.

here is the spec sheet for your oven

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes. Then let us know if the hard reset does not fix it.

You can download most Panasonic owner's manuals here. It will tell you how to turn off the Child Lock.

Check that particular outlet for a neutral ground

H95, H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.

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

I would recommend that you contact your nearest Panasonic-authorized servicer.
