Question about Emerson Microwave Ovens
I have emerson mn 9113ss microwave that went dead on me. The fuse and the other electronics are good. When you turn it on it lights up and the timer works. I cannot remember if the turn table spins. It just does not heat up. What can I do to fix this problem?
If the turntable in not turning, it's probably be a bad door switch or door switch mount.
See these links:
If the turntable does turn, then it is probably a bad connection or component in the high voltage section.

The most likely problem is the magnetron. Check your warranty in owners manual, I believe you have five year warranty on magnetron.

SOURCE: My microwave does not heat anything. The touchpad, exahustfan, light works. The motor turns on and turn-table works for the number of mins specified but does not warm up the stuff. Please help!
Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.
The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.
There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

Sounds like the magnetron has failed. There are some high voltage circuits that feed the magnetron and you can potentially get hurt if you don't know what you are doing. Would recommend you have it serviced by a professional if you want it fixed, otherwise look for a new one since the cost of repair can come close to the price of a new microwave oven.

A microwave can be dead for many reasons.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open.
When it cools, it closes the circuit and allows power through again.
If it's random, it may be a bad connection, usually on the control board or fuse holder.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.
