Can panasonic microwave oven nn-cf771s be built in to kitchen unit?

Hello, Vishal -

I have not yet found a manual for a National microwave model NN-K577F online.

The National brand was a subsidiary brand of what is now known as Panasonic. National brand kitchen appliances stopped being manufactured in 2008.
Source of information:
https://en.wikipedia.org/wiki/National_(brand)

The Panasonic company may hold a copy of the user manual for the NN-K577WF model in its archives, however.

Panasonic is headquartered in Japan. However, unless you reside in Japan, I suggest you contact the Panasonic division located where you reside:
https://www.panasonic.com/global/support/get_support.html

On the home page for the Panasonic division in your country, there should be a Contact Us link or a Live Chat link. Ask if the company Archives holds a copy of the manual for the National microwave oven NN-577WF or the Panasonic microwave oven NN-577WF and if you can obtain a copy. Note: There may be a charge for a copy.

Best wishes.

if your unit is attached to the kitchen your need to use the screwdrive for to loose and remove the microwave.

3) caution can be there to due the magnetron (valve electronic), and proceed to unscrew with screwdriver and take out the board.

No that is a very dangerous situation. What is sounds like is you had a short that blew apart but not completely damaging the wires. You should unplug, and open it if its out of warranty and inspect the wires. If the wires are partially burned it can heat up and cause an electrical fire.

there is a switch to turn it on or off. the turntable is replaceable

the sides snap out

Finally built up the courage to call GE Appliance number and weave my way through the phone menu system. Pressed the right menu option (sales) to speak to someone about trim kits. Found out that the trim kit model number is JX1527MWW. Then called back to select a different menu option (other) and learned from someone else that since the trim kit model is more than 1-2 years old, there's a slim-to-none chance any new microwave models will work with it, and even if there was they couldn't easily cross-reference against a model that old to tell me which one (or something to that effect). So I hit a dead end. Only option for me at this point is to buy a new microwave with new trim kit.

(Personal note: I think the trim kit business is a racket, in bed with the microwave manufacturers. Why else would there be no standard dimensions for microwaves by now--like refrigerators have--and why is it a few pieces of sheet metal cost over $150? Pretty convenient that every microwave model needs its own trim kit model!)

follow the incoming mains lead into the microwave their is a small pcb with a fuse their check this first

You mean NNS254? You can download your owner's manual here.

On page 4, it says, "If this appliance is to be vented inside the kitchen, be sure the charcoal filter kit is installed in the unit before you operate."

Also, on page 28, "The Charcoal Filter cannot be cleaned and should be replaced periodically every 6 to 12 months, or more often if necessary."

So the answer is "yes".

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

These are countertop units. If you do enclose it, be sure you ventilate it adequately. If is not designed to be enclosed.
