Electrolux Microwave producing a burning smell
When an Electrolux microwave smells like burning, stop using it until you identify the source. The most likely cause is a damaged or loose waveguide cover that is arcing or burning. If the cover is cracked, scorched, or will not stay in place, replace it. Next, inspect the power supply board for burn marks or a shorted component. A defective high-voltage capacitor, also called a capacitor, can overheat and create a burning smell, especially when it works with the high-voltage diode and transformer. A damaged thermostat may also show burn marks or other visible damage. Finally, clean the interior cavity thoroughly because food debris and splatters can continue cooking and produce a burning smell. These checks can help diagnose a microwave burning smell, microwave smells like burning plastic, or a microwave that smells burnt. Replacing a waveguide cover may be straightforward, but any repair requiring removal of the outer cabinet involves lethal high-voltage charge. The high-voltage capacitor can remain charged even after the microwave is unplugged and must be properly discharged before interior work. If you are not familiar with capacitor discharge procedures, use a qualified technician. Enter your model number to find the exact Electrolux replacement part for your microwave.

02 - Electrolux 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 - Electrolux 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 - Electrolux 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 - Electrolux 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
