Our emerson microwave will not make anything hot.put in time for something to cook it runs fine but it will not make the food hot HELP!!!!! the sides and top and bottom of microwave are warm but food is cold. tried heating frozen microve macaroni and cheese from schwans heated it for 5 minutes and it still was ice cold.

If you have this model microwave and it was working fine, then one day it stopped heating items placed inside there are a handful of different issues that could be the problem. In my case it was intermittent, over a period of a few days it would sometimes work (heat) and sometimes not. NO MATTER if this is what your's is doing or if it stopped heating all together. If you decide to let it dry out, or not use it for a while to see if it was a one time occurrence, or whatever the reason, the first time you put something in and probably for the next 10 times at least (this assumes it starts to work again), make sure you are right there with it while it is cooking. Don't assume you can put something in, go do something and come back when the timer is beeping. There is a chance (as this happened to me) that your food inside will CATCH FIRE! Normal food item placed inside, no metal, nothing different than the numerous times before when this had been cooked but when we smelled smoke we came running. Fortunately it started and finished inside the microwave but that's not a guarantee, it could spread. Play it safe. Never had a problem like this before and never heard of a microwave cooking something until it caught on fire (especially since the time entered for the cook was 30 seconds) but it did.
