Amana Microwave producing a burning smell
When an Amana microwave smells like burning, stop using it until you identify the cause. The most likely problem is a damaged or loose waveguide cover, which can arc or burn inside the cavity and should be replaced if it has burn marks or will not stay in place. If the cavity is clean and the waveguide cover is intact, inspect the power supply board for burn marks or a shorted component. A failing high-voltage capacitor or capacitor can overheat and create a burning smell, while a damaged thermostat may also show scorching or other visible damage. Food debris left on the interior can continue cooking during each use, so clean the cavity and remove all residue before testing the microwave again. Any repair that requires opening the outer cabinet must be handled carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. Proper capacitor discharge is required before interior work, and repairs involving the high-voltage capacitor may require a qualified technician if you are not familiar with the procedure. Enter your Amana microwave model number to find the exact replacement waveguide cover, power supply board, capacitor, or thermostat for your appliance.

02 - Amana 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 - Amana 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 - Amana 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 - Amana 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
