Please reply back with your brand and full model number, as well as the exact problem you're having.

It sounds like you may be describing the waveguide cover or the turntable.

Magic Chef MCD1311ST: Our microwave oven no longer beeps. Is there a way to fix the problem?


I assume you are certain it isn't your hearing going bad - sometimes the high-pitched tones of beepers become inaudible without properly functioning hearing aids, or the ability to hear certain tones disappears altogether. This is easily checked by asking someone with known good hearing if the beeper is working. Hearing problems can occur at any age, so don't dismiss this too quickly.

If everything else works normally, it is either the beeper (usually a piezoelectric disc on the controller board or attached to the board with wires, but sometimes a small speaker) or a fault in the controller board's beeper circuit. The first thing I'd do is check the disk and any wires for cracked or loose connections. (CAUTION: unplug the oven before removing the cover.) It's usually located on or near the controller board behind the key panel. Generally, piezoelectric discs are about 1/2" to 2" in diameter, have a brass rim with a silver plated ceramic center, and may be enclosed in a drum-shaped black plastic housing with a hole in the center to let the sound out.

If the disk is connected to the controller with wires and a removable connector, unplug the connector, clean the pins and test it. Piezoelectric audio devices use very little current, but a dirty or oxidized connection will still keep them from working. It is possible that the disk itself has mechanical (spring) contacts, and the silver electrode plating at the contact is tarnished. In that case, gently clean the silver with a soft white pencil eraser. Do not over-polish; the silver film is very thin.

Is is possible, but difficult, to repair a cracked solder connection on the disk. You must use an acid-free solder flux and silver-bearing solder (3% silver recommended), and you must work quickly using an iron at the correct temperature for the solder or you will completely detach the silver film from the disk.

If necessary, you can find replacement disks at electronic component vendors such as Mouser Electronics. The primary specification is the frequency (musical pitch), given in Hz or kHz (Hertz or kiloHertz). If you don't have that number, getting a disk of the same diameter will probably be close enough. You'll want one with wires or PC leads already attached. piezoelectric Audio Devices Mouser

My emerson microwave #mw8999rd shoots out fire from a silver piece of cardboard thats on the righthand inside of my microwave oven. whats with that?


There is electrical problem in your microwave heating circuit. This is a fire hazard and you should stop using this microwave and unplug from the outlet. This is not something you can fix and the fuse does not protect your system anymore. The best choice is to purchase a new one and throw this away.

What is the cardboard (silver) for inside the microwave, our got dirty and my husband threw away, Is microwave still good?


The ALLUMINIUM FIBER PANEL is to prevent microwaves to erradiate whatever is on the other side, so YES it is essential, and YES the oven will worke (BUT FOR HOW LONG ???) that is the question... you should replace the panel (unless the oven is old and you were planning to replace it) in that case, use it until it dies...

When food soils the inside of any oven it must be cleaned immediately, if the food is left without cleaning it will degrade the inside coating (special paint) and expose the metal thus reflecting microwaves in the magnetron and damage to the magnetron will occure...

Cheers!

Does a kitchenaid microwave have a fuse inside


Yes it does, unplug unit, remove back cover, "2 to 6 screws" on the right side look for a silver rectangular capacitor, discharge it across the two pins with a long screwdriver, next look for a ceramic fuse, "white body with silver ends" remove and replace with same type and rating. If the fuse blows again it indicates a bad door switch.
