Panasonic has two documents in the Owner's manual section on the product support page: https://shop.panasonic.com/support-only/NN-T664SF.html . The current link for the NN-T664SFT basic operating manual is ftp://ftp.panasonic.com/microwaveoven/om/nn-t664_mul_om.pdf . (Note: the final letters indicate the color of the microwave and other minor differences.)

I hope this helps.

Call the Customer Service Center to see if they can offer any assistance.

You may simply need to purchase a new one, as the repair cost may exceed the cost of a new microwave oven.

Panasonic NN ST652W Manuals

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.
