Gaggenau Microwave producing a burning smell
When a Gaggenau microwave smells like burning, stop using it until you identify the source. The most likely cause is a damaged or loose waveguide cover, which can arc or burn as the microwave runs. Next, inspect the power supply board for burn marks or a shorted component. A defective high-voltage capacitor or capacitor can overheat and create a burning smell, followed by a damaged thermostat. Also check the interior cavity for food debris or spills that may continue cooking and produce a microwave burning smell. Clean the cavity thoroughly and replace a damaged waveguide cover before testing the appliance. 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 a qualified technician should perform repairs involving the high-voltage capacitor, high-voltage diode, high-voltage transformer, or power supply board if you are not familiar with safe discharge procedures. Enter your Gaggenau microwave's model number to find the exact replacement waveguide cover, power supply board, capacitor, or thermostat for your specific appliance.

02 - Gaggenau 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 - Gaggenau 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 - Gaggenau 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 - Gaggenau 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
