In here the important issue is the bowl is microwave safe or not.
One popular method of testing if a particular glass is microwave safe is to microwave the container while it is empty for one minute. If the container is hot, then it is not microwave safe. If the container is warm, it should be fine for heating food. If the container remains cool, you can cook in the microwave with that container. Check to see if it's marked as microwave safe or ask the manufacturer before using in a microwave.

So is your ceramic bowl really microwave safe or have they just put on the label. You may test another known microwave safe bowl in your microwave to be sure. Your microwave oven should be fine.

Hope this helps.

    It is definitely microwave safe since it worked fine in my previous microwaves. I just bought this one used from someone but there was no mention of this being a problem. Sounds like my microwave is broken? What would you do?

    An info about ceramics:

    Ceramic dish with silicon carbide become very much hot in the microwave. It is because the molecular structure of silicon vibrates at the same rate of frequency as the radiation from the microwave. So the material that contains less silicon, water particle, clay etc should be less hot than others.

    But I am not sure that all the microwave safe labeled ceramic dishes should not be too hot. Some brands becomes hot as I know. Before trying to repair the oven you should be sure of that.

    I advise you test your oven with microwave safe glass bowls/dishes rather than ceramic.

    If your microwave oven can not pass the test then you should change it.

    I would like to be sure of it. I can not say anything about repairment.

    Kind Regards.

Hi. Our 1 1/2 year old Sharp KB6524PS Microwave Drawer: While cooking oatmeal, at start of cycle, the microwave started arcing, then smoking. Shut off at 15 seconds. Microwave-safe china used.

I expect the arcing came from the waveguide cover or aerial cover having either a crack or carbonised food particles on it.
A new cover may affect a cure if the magnetron is not damaged.

All controls,lights,fans are normal. Turntable, microwave, convection do not work. Internal fuse?

There typically is an internal ceramic fuse. It is usually near where the power cord enters the oven, or behind the control panel (on over the range units).

The problem you are describing, though, sounds like it may be an open thermal protector on the cavity. Most are diamond shaped, with two wires. Unless the cavity is extremely hot, it should show continuity.

Unable to eliminate odour from previous cooking despite the fact that I wipe the microwave with a soapy cloth & then with a clean cloth each time to Microwave is used

  1. Fill a plastic bowl with 1 qt. of warm water. Add 2 tbsp. of liquid dish soap and 1/4 cup of chlorine bleach to the water. Thoroughly mix the solution.
  2. Dampen a clean cotton rag in the solution. Wipe all inside surfaces of the microwave with the soapy rag to remove food debris and stains. Scrub stubborn residue with a nylon scrub brush.
  3. Moisten another cotton rag with warm water. Wipe the microwave surfaces with the rag to wash away soap and loose food debris. Thoroughly rinse the inside of the microwave.
  4. Dry the microwave's interior surfaces with paper towels. If odors remain in the microwave, fill a microwave-safe bowl with 1 cup of cool water. Add to the water 2 tbsp. of baking soda, half of a chopped lemon (including pulp and rind) and four whole cloves.
  5. Place a microwave-safe plate on the microwave turntable. Set the bowl on the plate.
  6. Heat the microwave on high for three minutes. Operate the microwave according to the manufacturer's directions. Keep the bowl in the microwave for 15 minutes.7
  7. Remove the bowl from the microwave. Wipe the microwave's interior surfaces with clean paper towels to remove steam moisture.
  8. Leave the microwave door open overnight to completely air out any remaining odors.

    Just need general how to use and clean info

    Just fill a microwave-safe bowl with a mixture of half vinegar and half water, and nuke it for two minutes. Then, dip a sponge into the vinegar-water solution, and use it to wipe the food off of the walls of the microwave. It'll fall right off - no strong-arming required.

    No chemicals, cheap and works like a dream.

    5 yr old microwave has worked perfectly - until now. Put small amount of food on a safe plate in for 45 seconds. Plate suddenly cracked, was extremely hot - and food wasn't even warmed.

    The plate wasn't microwave safe or has a crack in it that had moisture in it to cause it to split.
    A new pyrex type glass plate will get it going again.

    I covered the plate with 'heavy duty aluminum foil' thinking it was safe for for microwave use, then I saw a sparkle inside while turning. I stopped it, took off the aluminum cover, turned the microwave...

    The food is safe as long as the food has not got oxidized aluminium on it.
    Microwave energy is very high and will melt metals!
    As long as it is not arcing any more there should be no problem.

    My ifb microwave oven is getting hot outside while

    Normally when u cook food in microwave the fod is cooked by microwaves, which means the heat is generated with in food. The temperature inside is never too hot and all the heat produced is absorbed with in the food.

    On the other hand when the grill is switched on, a separate heatting element gets switched on. You can see this red hot element on the top side of inside of microwave. the heat from this element gets transferred to food through air circulation. But partof heat also gets transferred to the walls of microwave oven. This is the reason the wall feel hot during use of grill.

    As i see ther is no problem with the microwave itself. Jut kep delicate thngs a bit away from the microwave.

    Plate getting too hot

    I don;t think your plate is micorwave safe. Put the plate and a glass measuring cup with water in the microwave for 1 minute, if the plate is hot and the water is not the plate is not microwave safe. IF the water is hot and the plate is not. I don't know what the problem is
