What is convection cookong

A convection microwave is a combination of a standard microwave oven and a convection oven. It allows food cooked in the convection microwave to be cooked quickly, yet come out browned or crisped as in a convection oven. However, most cakes cannot be baked in a microwave oven - only those without an open grain structure, such as brownies. There are microwaves which contain electric browning baking elements. A true convection microwave has a high velocity forced air fan to circulate the hot air uniformly.

My whirlpool microwave built in oven emitted smoke

Hi Dagmar
So... you've indicated that your microwave oven has an obvious serious problem.
You didn't have any questions?
The Answer would be pretty obvious anyway!

Better Luck with the New One!


The main component in a Microwave oven is the Magnetron. This generates the microwave energy which is released into a resonant tuned cavity (antenna) that heats the food. Testing the Magnetron would require specialised tools & knowledge. Beside the fact that it would be very dangerous. The Magnetron is often driven by electronics like a switch mode power supply & an inverter. It is possible that the switch mode or inverter has failed and burned out. There can be Electrolytic Capacitors that have failed (leaking or popped) causing the electronics to fail. If you have some expertise in this area then you could open up the unit and inspect for what has failed. Unplug power and never operate the unit while inside. Pull out suspect electronics module's, repair and seal unit up before turning on. The mere fact that you had heated internals is a warning of major problems.
Really, you are better off & safer taking the unit in to a Microwave Repair Technician.

I put a mug of water in the microwave, left the room. Came back, and the room was filled with a burning electrical/plastic smell, no visible smoke. Now, the microwave completely powers off after 1 second...

Since there was no smoke, it's not a transformer. It's most likely a high voltage diode or magnetron. The magnetron would be over heating and opening a thermal cut out mounted to or near it.

I have a Hamilton Beach 900 watt microwave that will run but will not heat the food

maby it's the magnetron, i need more information, a good way to test the magnetron is to put a small HE-NE lamp in a glass filled with water (HE-NE lamps) are found in any radioshack (La source) store, if the lamp glowes orange it meens the magnetron is good, if it is not glowing then the magnetron is dead, (the magnetron is allmost the price of the oven) it could be a fuse but if you have to change the fuse replace it with the same type (normaly ceramic german type) NOT GLASS

Good luck!

What would cause a electric stove oven to smoke out the oven vent after you cleaned the oven inside completly

There may still be some crumbs left behind that you didn't get completely wiped out; assuming you did wipe it out. It could also be the broiler pan if it was in the oven.

Fire in Microwave Using Sensor Control for Potato

Please contact your home insurance to have the problem logged as a failure of the microwave. The insurance company will most likely help you with the smoke damage to the house and will contact the manufacturer to get their money back... there might be an issue with the manufacturing of these appliances.
