Kenmore convection microwave burnt rice and bowl black sticky film noticed by fans area and inside looks discoloured smells burnt from rice and bowl that were black burnt....

Hello -

It is probably safe to use the microwave oven after removing the burned smell.

I found some methods for removing a burned smell from a microwave.

From:
https://blog.bostonappliance.net/5-foolproof-ways-to-get-burnt-popcorn-smell-out-of-the-microwave/

(Quote)
1. Fill a bowl with 1/2 cup water and 1 tablespoon white vinegar.

• Microwave it for 4-5 minutes and leave it with the door shut for 10-15 minutes.
• Steam will loosen smell-causing detritus stuck to the walls. Vinegar absorbs odors, even stubborn ones like burnt popcorn smell.
• After the waiting period, remove the bowl and wipe the inside of the microwave down with a paper towel

2. Not good enough? Okay - soak a sponge with vinegar.Place some baking soda on top and microwave the sponge for 25 seconds.

• Wipe the inside of the microwave with the sponge.
• Don't forget the glass tray and the microwave door.

3. If steps 1-2 don't remove all the grime, soak cotton balls with acetone-free nail polish remover and wipe down the inside of the microwave.

• Even stubborn stains should come out.
• Wipe down the inside with soap, then vinegar water, to remove the polish remover.
• We recommend following through with step 4 to get rid of chemical smells.

4. Banish the remaining smells with the power of citrus.

• Peel two oranges or slice a lemon in half.
• Place the orange peels or lemon slices in a bowl of water (1-2 cups).
• Microwave it for 4 minutes. Watch closely to ensure that the water stays in the bowl and the citrus peels do not burn.
• If possible, leave the bowl in the microwave (with the door closed) for 12 hours.
• Too time-consuming, or just not doable for you? That's okay too. Let the bowl sit in the closed microwave for half an hour then, if the burnt smell persists, continue to step 5.

5. Still bad odors in your microwave? Leave an open box of baking soda on your microwave tray overnight.

• It will neurtalize the odor without adding to the smelly situation in any way.
• You can also place coffee grounds from your morning coffee in a bowl in the microwave all day while you are at work.
• If you don't mind coffee smell, you can microwave 2 tablespoons of coffee grounds in a half cup of water for 2-3 minutes to expedite the process.

Microwaving cloth is not a good idea. Rather than drying out the moisture (or for whatever reason it was put in the oven), microwaving it will just make the water really, really hot! You could easily burn yourself trying to handle the item. The heat could also damage the fabric itself or even ignite it....which it looks like happened.

The microwave oven should be safe to use but you need to remove the odor.

A couple of ways to try to get rid of the burnt odor:
Fill a microwavable bowl with 1/2 cup water and 1 tablespoon white vinegar.

1. Microwave it for 4-5 minutes and leave it with the door shut for 10-15 minutes.
2. Steam will loosen smell-causing detritus stuck to the walls. ...
3. After the waiting period, remove the bowl and wipe the inside of the microwave down with a paper towel.

A different way is put two tablespoons of baking soda in a microwave safe bowl and add a cup of water on top of that. Then put the bowl in the microwave for three minutes. The baking soda will kill the funky smells and the water will start to steam clean the spots and stains.
Good luck with your troubleshooting.
Helpful?

time for someone to unplug it and look inside, if something smells like it burnt do not plug in etc.

Common failure parts in most microwaves are:

Diode most use:





Magnetron which is connected to the inverter most use (circuit board)






AC filter cap which varies in shape some what but can be still tested with a ohm meter, also if really bad will be buldged out on sides or top.

Hi,

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....

Basic Microwave Oven Troubleshooting Tips

First, wipe out any excess crumbs. Then fill a microwave-safe bowl with about 1-2 cups of water. Add some lemon juice, or put in half a piece of fresh cut lemon (squeezing some juice out first) into the bowl... Microwave until the water is boiling. Then let it sit for a few minutes to let the steam penetrate the interior. Carefully remove the bowl and interior tray. Wipe down the interior with a damp cloth. Wash the tray in the sink with dish soap, dry, and then return to microwave. For the outside, spray with a kitchen cleaner and wipe with paper towels. The main idea is that the steam from the water will loosen food particles, and the lemon will add a fresh smell.

This looks that the motor is not being functional, for that you have to look for the fuse if one. or else check the circuit if any wire is disconnected or burnt out accordingly you can decide what needs to be done.

You would be better off to replace the filter. Purchase two and use the first one to capture the remaining smoke residue. Then install the other clean one to keep microwave free of smell. Check the web site www.partselect.com for the replacement filter. If you found any of these suggestions helpful, please rate my solution. D. Lange

don;t worry;
all you need to do is lubricate the fan bearings with light machine oil and make sure the fan is not hitting anything

If it is burning and arcing at the antenna, it is probably arcing in the wave guide area. Probably will have to replace unit. I have had some success by removing the antenna, sanding and repainting the burnt areas of the cavity and sanding off any burnt marks on the antenna. Need to look at top of mag to see if also arcing there too.
