Microwave interior coating is flaking off

By Kirk769 - 11/2/2018 2:16:20 PM

We've discovered a large spot in the back corner of our Panasonic NN-SN671S microwave where the coating has flaked off and appears to have rusted.  I've heard before that any bare metal in the cooking area inside will cause an arc that will destroy the magnetron or whatever you call it.  Is there a patch kit that we can re-coat this interior with to keep our microwave running?

Thank you for posting, Yes, yo do not want bare metal showing inside the microwave. You need a microwave cavity paint .. no primer is needed... something like this

Well, I went ahead and scraped all the rust spots along with the big one down to the metal then put no telling how many coats of the Appliance Repair Paint on it and the rust spot came out again so I'm not going to waste any more sweat over it.  The oven is still working after 10 months on now so I guess we'll use it until the time it finally zaps itself into the next world.  I did make everyone wait for a couple of days to let the paint cure, though.  Talk about withdrawal symptoms!  I figured the paint in the can was what they applied in the factory.

How in the World did I wind up with a "Supreme Being" rating?

The forum updates criteria about 3x per year.. you just happened to see it while it was updating, it does weird stuff for 1-2 hours then it returns everyone back to the normal position
