Door Release Button not working on Panasonic Microwave NN-T664SFT

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.

busted plastic part in microwave send model # we can find the part you need

Don't order a new button. Here's what I did. I have had many issues with my Panasonic microwave ovens - the button more than once. I even ordered two new buttons from a reliable source and one of the boxes had the wrong button inside. Today, instead of ordering ANOTHER button, I fixed it simply with a bolt and washer. Precisely: the button is built with two hooks, two prongs, and a central "tube". I used a #10 phillips head machine screw (bolt) 1/2" - 3/4" long and a #8 washer (plus Loctite: optional). You need to open the washer's hole slightly to fit over the #10 bolt. Then simply put the button and spring on the bezel and install the bolt from the rear. The washer will trap the bolt in the bezel, but pass through the frame to operate the latch.

It may be a broken door open button, door open lever, or grease in the channel where the door open button moves in the control panel frame.

You can order Panasonic parts from Encompass here but without part numbers, it may be best to call them toll-free at 866-779-5835.

Take side panels off and press the button through from the back, my husband has just done this tonight on our Panasonic microwave model NN-ST477 as the door would not open. He found a piece of plastic like a hook had snapped off. The door now opens and functions normally. Took about 30 minutes to do . If and when it becomes stuck again we know that we will need a new replacement button. Hope this helpskind regardsChristine

Yes, to take down the face you must have the unit fully accessible - the bolts are accessible only from the rear.

OUTDATED POST - PLEASE REMOVE

I have the NN-T994 SFR model and it had a switch that was staying depressed. I removed the screws to (in my case) the stainless steel cabinet, removed the cabinet and unhooked the wires to lay it aside. Found that the switch was cracked or broken, glued it back exactly as it was, then put the cabinet back on and it fixed it! Now about a year later, I have another problem...oh well. Hope this works on yours.

Our technician suggest that there may be a problem with the Inverter Board in this model, which is something that would need to be looked at by a Service Center.

In rare cases it could be the door switches.
