Microwave 8 months old. Is this a warranty issue?
Check your users manual and if anything is under warranty it must be serviced or replaced by an authorized facility or the warranty will be void.

Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

no never heard the cooling fan kick on after it shuts down, no power at all.
SOURCE: the fan starts up and runs on its own and we are cooking
That is a normal safety feature.
That's only covered in a very subtle note in the hood fan section of your owner's manual:
NOTE:If the temperature gets too hot around the
microwave oven, the fan in the vent hood will
automatically turn on at the HIGH setting to cool the
oven. It may stay on up to an hour. When this
occurs, the fan can not be turned off.

Ok just figured this out! It is a problem with the alignment on the lower door switch. I took the cabinet off and lifted up on the door switch slightly and voila! It works. You could probably fix this without taking it apart, just lift up on the door ever so slightly. I hope this works for you.

I bought my emerson microwave 3 years ago model# mw8115ss from walmart and have had all the problems that everyone has talked about and I thought about throwing it away until I thought about one small detail, the FUSE. China uses junky glass fuses that burst instantly with a slight power outage, door slamming to hard, moving it around, and of course constant use like myself always heating up water for bottles. I took the back of the microwave off and walla!!! a blown fuse, but wait!!! dont buy another glass fuse!!! go to your local home depot and get the ceramic fuse for microwave ovens!!! they are $2.83 at my local home depot. I replaced the junky glass fuse with the ceramic one and it has worked perfectly for six months now.
DONT let someone tell you that you cant replace a glass fuse with a ceramic one because they are full of boloney. My microwave did all kinds of things, it wouldnt turn sometimes, it would come on by itself, it would beep for no reason, turn but not heat up, you name it I had the problem. When a fuse starts to go out it can make your appliances do some strange things, check the fuse and replace it with a CERAMIC one and I promise it should eliminate your problem.
