Question about Panasonic NN-S963BF Microwave Oven

NN-S963BF begins operating when door is opened

Without setting cook power and time our microwave begins operating when the door is opened and stops operating when the door is closed. Seems to heat food fine and not sure if it's cooking when door is opened. Light comes on, tun table rotates and oven makes same sound when it's actually cooking. Any ideas how to fix. We've had this for 10 years without any problems.

The door switch is bad. https://www.partstore.com/Model/Matsushita/Panasonic/NNS963BF.aspx

This site has the most parts. See if there is a contact list so that you can ask about the switch. I dont see it listed as a stand alone item.

SOURCE: Panasonic Microwave oven - cooking operation stops afer 2 seconds

Sounds like a short in the microwave circuit. One or more of the following four components has failed -

Transformer
Magnetron
Diode
Capacitor

Repair is not for the amateur, unless you know how to take things apart, and put them back together EXACTLY as the were found.

Parts are available on the Net, and you can get the P/N's off the old components to identify suppliers of the new ones.

Don't try and measure resistance of the diode. It's impedance is far too high to get a good reading. They're cheap anyway. Always replace the capacitor, they're cheap too. No way to test the magnetron, and the transformer is not easy to test either.

SOURCE: panasonic microwave nn-s963bf making grinding noise

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

You can
order parts for this brand from Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

My nn-s963bf starts operating when door is opened


The electronics have lost their marbles. When a nuker door is opened the safety switch connected to the door is designed to turn the unit off and not on. You just better work fast when you put stuff in or take it out!!!!!!!

Check the door switches if one is bad it may think the door is being opened and stop the unit from running. If it is from a bad connection it will get worse as it gets hotter while running.

Not heating


Hello


Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.

Repair

If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.

My microwave want cook


Hello

and/or circuit breakers, particularly in the case of recent power failure, and reset if necessary.


Unplug the microwave, wait 30 seconds and plug back in to the power supply to reset the microcomputer.


Open and close the microwave door firmly and press "Stop/Reset." Select a new cook time and press "Start."


Ensure a proper cooking temperature and/or time is chosen, as low cooking temperatures or short cooking times may prevent the microwave from heating food appropriately. Press "Power Level" to ensure the microwave is cooking at 100 percent power.


Contact an authorized service technician if the problem is still unresolved.

Burns my popcorn constantly. is there a different setting i can put it on?


HELLO.

Solution to your microwave problem is given as below.

* 1 Set your Daewoo microwave on a countertop near an electrical outlet and plug it in. Open the door and place the circular roller guide in the center of the oven cavity, then place the glass cooking tray over it.

* 2 Set your food on a microwave-safe dish and then put the dish on the cooking tray and close the door. Make sure that it latches properly.

* 3 Turn the upper knob to select a power level. Power levels include "Defrost," "Med-High," or "High." If your Daewoo has a touch pad, touch the "Microwave" button once to set the highest power level. Touch it consecutive times to lower the power level.

* 4 Turn the lower knob to set the cooking time. For cooking times less than two minutes, turn the knob up past the two-minute mark, then back to the correct time. For touch pad models, enter in the cooking time with the numerical keys and then press "Start."

* 5 Open the door at any time to stop the cooking and check the temperature of your food. Shut the door to automatically continue cooking, or turn the timer knob to the right to add more time. For touch pads, press the "Stop/Clear" button, then key in a new cooking time and press "Start."

* 6 Open the door when the timer reaches the "Off" position and take out your food.

Thanks.

Just purchased our Cuisinart Stainless Microwave, plugged it in, read the operational instructions and set the clock. As a test, we tried to heat water....does not work. Any suggestions?


Yes! Take it right back to the store for exchange, cause could be a bad magnetron "that heats food" and a couple parts that work together with the magnetron,or there may be issues with the keypad, none of these will be cheap to fix.

We have a frigidaire microwave and in the middle of cooking, the motor stopped. The clock and cook time continued to work, but no heat. We've tried using at half power, on defrost, etc. but nothing seems...


What you are saying the microwave stop work like heating,but but the clock counts down.If it is stop heating then there is a rest on or near the magtrogron.Once it cools down it start back heating.Open and close the door will reset power to the magtrogen{sorry about the spelling].Look for loose connector,or replace the click zon it should have a small red buttom on it.
