Danby Microwave producing a burning smell
If your Danby microwave smells like burning, stop using it until you find the source. The most likely cause is a damaged, loose, or arcing waveguide cover, also called a mica sheet, especially if food or grease has collected around it. Next, inspect the power supply board for burn marks or a shorted component. A failing high-voltage capacitor or capacitor can overheat while working with the high-voltage diode and transformer, creating a microwave burning smell or burning smell from the microwave. A damaged thermostat is another possible cause. Finally, check the interior cavity for spilled food and debris, which can continue cooking and produce a microwave smells like burning odor during each cycle. Replace a damaged waveguide cover or other failed part, and clean the cavity before testing the appliance again. Any repair that requires removing the outer cabinet, including work on the high-voltage capacitor, high-voltage diode, high-voltage transformer, or power supply board, is hazardous because the capacitor can store a lethal charge even after the microwave is unplugged. It must be properly discharged first, so use a qualified technician if you are not familiar with capacitor discharge procedures.

02 - Danby Microwave Power Supply Board
If you've confirmed the oven cavity has been cleaned of all food debris and the waveguide cover is in good condition, a defective power supply board could be one of the components producing a burning smell. You should inspect the board for any burn marks or a shorted component and replace if necessary.

03 - Danby Microwave High Voltage Capacitor
The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. A defective capacitor may overheat and produce a burning smell. Inspect the capacitor for visible damage or burn marks and replace if necessary.
Highly Likely
04 - Danby Microwave Capacitor
The capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. A defective capacitor may overheat and produce a burning smell. Inspect the capacitor for visible damage or burn marks and replace if necessary.
Highly Likely
05 - Danby Microwave Thermostat
If you've confirmed the oven cavity has been cleaned of all food debris and the waveguide cover is in good condition, a defective thermostat could be one of the components producing a burning smell. You should inspect the component for any burn marks or damage and replace if necessary.
Highly Likely
06 - Interior Cavity not Clean
Food that is left on the interior of the microwave can continue to cook each time the microwave is used, resulting in a burning smell. Always cover food when cooking to avoid splatter and wipe up any spills after use.
Highly Likely
