Crosley Microwave producing a burning smell
When your Crosley 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. Clean all food debris from the cavity, then inspect the waveguide cover or mica sheet for burn marks, cracks, or damage. If the cover is secure and the cavity is clean, a defective power supply board may have a shorted component or visible burn marks. Next, inspect the high-voltage capacitor, also called the capacitor, for swelling, leaks, overheating, or burn damage. A faulty thermostat can also create a burning smell by overheating. Food splatter left inside the microwave can continue cooking and cause a microwave burning smell, burning smell from the microwave, or a microwave that smells like burning plastic. Any repair that requires opening the outer cabinet involves serious electrical danger. The high-voltage capacitor can store a lethal charge even after the microwave is unplugged and must be properly discharged before interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician inspect the microwave. Enter your model number to find the exact replacement waveguide cover, power supply board, capacitor, or thermostat for your Crosley microwave.

02 - Crosley 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 - Crosley 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 - Crosley 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 - Crosley 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
