Question about Microwave Ovens

1 Answer

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.

There is no reset button on it, since there is no processor to reset.
This is how your oven works: there are 2 transformers, one for the low tensions, to power the electronic board, and one for the high (light bulb and motor) and very high tension, for the magnetron. When you plug it in the low voltage transformer powers the electronic board and allows you to program it - and that works well in your oven. When you push the Start button a relay is activated in the board - that relay switches from powering the light bulb to powering the high tension transformer that starts the motor and the magnetron (the special tube that generates the microwaves) - this is the problem in your oven: this no longer works.
Only 3 things can fail there: the transformer itself, the filtering capacitors or the magnetron. To find out which the oven must be opened and the parts tested. This is a job that MUST be left to a pro: there is over 5,000 volts there, you must use a very special multimeter to test them, otherwise you will be killed instantly when you touch it.
Take it to a repair shop, your life is worth more than a few hundred bucks.

Whaqt are the dmensions of panasonic genius premier model number nn-s7768a

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)

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!,d.aWc

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.

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.

My panasonic genius sensor microwave says lock. How do i get it unlocked?

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.

Panasonic Model NNS768BA Genius Premier 1100W Display works - nothing else comes up H98

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.
