Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the stirrer cover in the ceiling of the oven.

The cover and the areas behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

If your cover is burned, it will need to be replaced. It provides important protection for the magnetron.

You can download Whirlpool owner's manuals and installation instructions here. The manual covers removal and cleaning of the cover.

Is it normal for a microwave to make crackling noises when standing and not in use but plugged in ?


A microwave in standby mode should not crackle. There might be a slight humming sound from a transformer, but that should be all the noise it makes. You could have a transformer or control panel component that is failing.

My kitchen aid microwave makes a loud crackling noise every once in awhild


Is it a carousel (turning platter)? if it is, than it is probably dirt on the platter support wheels and the platter support groove/track on the bottom of the oven, clean the glass plate, the support wheels, and the bottom groove as well, if you want to make sure the crackling comes from the carousel system, take it all out (support and platter) than place a glass of water in the oven and start it, if there are no crackling noise than my theory is correct, if the noise is still there than have it checked by a professional technician...

A number of days ago we put two plates of food in the microwave to reheat them. There was a snap, crackle, pop noise. We checked to see there was no metal object in the unit....there wasn't ...we know...


Are you sure the plates were Microwave oven safe? Some dishes have metal in the colors of the design. A snap, crackle, pop noise normally means there is metal present in the oven.

When using the oven tonight, i saw sparks coming from the plasic clip on the right that holds the rack up. i tried again later and still hearing crackling/sparks. is it possible to replace that...


Yes it is possible to replace the plastic clips. However thats not the problem. The problem is exposed metal under the plastic clip. Remove the clip and you will see it. You need to sand it down so that it is smooth, then use ceramic paint to cover up the exposed metal. You should check under all 4 clips to be safe. Clips are a little tricky to get out, just insert a screwdriver on either side and pry gently.

Rattling, crackling type noise just started and is constant when microwave is running.


A couple of months ago my microwave started making crackling, rattling and grinding sounds everytime i used it and i thought it was going to break down. It turned out one of my children must have spillled or overflowed something with a clear liquid because the micro did not look dirty but there was a crunchy substance under the wheels of the turntable. Once i cleaned this up totally the noises all went away.

Hello! Everytime I start my Whirlpool microwave, it makes a loud crackling noise and I'm worried it's going to start sparking. Is there any way to fix this issue, or is it shot?


The cracking spound is the spark jumping. so if there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground. As you have mentioned it was stored, it is quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Now keeping clear switch on , use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues , you can use the microwave safely

My microwave is making a cracking sound like if it had metal in it but i took everything out and its still making the cracking sound. What could be causing this sounds if microwave is empty?


A contaminated wave guide cover will crackle and spark.
They should be periodically checked, cleaned or replaced.
Contact Maytag for replacement parts.
Hope this fixes your noise.

My microwave oven heats, but makes strange crackling noises. Is it allright to keep using the unit?


No. Please have it checkd as it is dangerous to let the high voltage jump along side the magnetron. This will eventually result in the failure of the magnetron with a possible damage to the circuits.
So open and check if there is any foreign particles/insects struck within , Is the insulation damaged or remove the magnetron and clean the uni , clean the cabin specially if food haas accidently got spurted inside, dry the whole unit after cleaning before you fix back the magnetron.
The microwave must now work without crackling or else if the spark is seem near the magnetron , it must be replaced.
Hope this advice helps.
