It has been making loud noise off and on for a few months but only lasted a couple seconds or I could stop and start it again and the noise would stop. Now the noise is constant and very strong smell and there are little black pieces that kind of look like ash. Definitely not a humming noise.

my guess would be the wave cover. sometimes they smoke and makes sparking sounds. does it still heat food?...if it does, then its not the magnetron.
SOURCE: MAYTAG MMV4205BAS Running but not heating
If the food in the cooking compartment is not heating at all, then you may have one of several components related to microwave energy generation that have failed or became disconnected internally.
Magnetron Tube, HV Capacitor, Filament Transformer or any number of sensors that disable power to the system. The control board could also cause the system to noty function correctly.. You wanted general inputs.. there ya go.. LOL
Not sure I told you anything you didn't already know but you should ask the tech what he did after he gets it going...

SOURCE: We have an MMV5165AAB Microwave oven, installed
the unit inside the microwave that heats called the "magnetron" has gone bad or the circuits that power the magnetron have failed. if its under warranty still, send it back to the manufacturer. if not you can call some repair shops and see how much it would be to service it, but its most likely going to be cheaper to purchace a new microwave since they are relatively cheap these days. microwaves are throw away product now days, they dont make them to last anymore, i hope this helps and good luck to you

If there is no heating please do not switch on unless you have confirmed the fault.The burning can be the magnetron or the capacitor. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron. Now keeping clear of the microwave, switch on, use a cup of water inside to test.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if contact is not through the microwave will not work.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely

The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.
