Weird rattling sounds

About five seconds after we start the microwave it has a strange rattling sound to the right. This microwave has worked fine since we bought it about a year ago. It still heats the food but we are concerned.

Re: Weird rattling sounds

It happened to me also, I read in the manual to take out the plate and roller ring and wash them - seems it could be a bit of build up that we can hardly see.....

Re: Weird rattling sounds

If it's less than a year old, it should be under warranty, and I wouldn't open it. I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

It may be a failing turntable motor, fan motor, but it really merits close inspection.

This is an inverter-based model, and due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

If you need your owner's manual, you can download it here:

Microwave smell like burning rubber

Good Afternoon Friend,

I understand that you are receiving a burning rubber smell from your Frigidaire microwave. I also see that your appliance will run for a couple of seconds, and then you hear a weird noise, followed by a burning rubber smell. I suggest contacting your local authorized technician, especially when dealing with your microwave. They will be able to diagnose your appliance and determine what is causing that sound as well as the burning rubber smell. Hope this is helpful.

-Best Regards-

Microwave caused lights to dim, then blew out a power strip

the noise you said sounds like the magnetron or h.v. capacitor or h.v. diode blew up,that could have created a voltage spike,as for the power strip fried, i would have someone check your neutral line in the house power panel, if it open or has a hi resistance spot it will in turn make your homes 120/240volt circuits a voltage divider because of a lack of the neutral wire and can cause problems too

Strange rattle when microwaving

Chances are the blade assembly has come loose on the shaft of the internal cooling fan.

This can be solved with a couple of drops of super glue at the spot where the blade and shaft meet, then allow it to dry for several minutes.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you'll see the cooling fan.

Please let us know what you find.

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