SOURCE: Not Heating!!

This seems to be a defective magnetron tube. Because of the very high voltage, (~5000 volts) you need to be experienced in this type of repair. Sending it out for service may cost around $150, so you need to evaluate the probable cost vs a new oven.

Arcing and bang noise


The arching is probably to the cabinet where paint is missing. This usually occurs at the edge where the microwaves travel into the cabinet. You can get microwave paint from your local appliance parts supplier. It's special paint that is non - conductive.

Microwave runs but doesn't heat.


The sound you heard was an Arc from the magnetron which provides the microwaves for heating, this means the magnetron has developed a short which unfortunately means you are now in the market for a new microwave as the cost to repair is not viable due to the decrease in replacement microwave cost over the last few years.

Loud Bang, then Light Stays On, Can't Cook


Something has failed in the high voltage supply to the magnetron. There are no user serviceable parts inside, but there are INSTANTLY LETHAL voltages present. Scrap the oven & get a new one, they are generally not worth reparing.
