Tips for preventing arc burn marks inside the cavity of your Viking built-in microwave

Clean the cavity often. For stubborn residue, place 1 or 2 cups of water in a microwave-safe cup. Bring that to a boil for 2 to 3 minutes. The steam will soften the mess so that it’s easier to clean out. Keep rack supports clean or they can start to melt.

Cover food when cooking or reheating to avoid splatter.

Don't store the metal rack in the microwave and only place the rack in the microwave when it will be used for multi-level cooking. When using the rack, insert it correctly so it doesn't touch the sides or back of the microwave cavity and it’s mounted correctly in all of the rack supports. Never place the rack on the floor of the microwave. Never use the metal rack when cooking popcorn. As the bag expands, it could push the rack out of position and create arc or burn marks.

Common replacement parts for Viking built-in microwaves

• High-limit thermostat. The high-limit thermostat detects a short circuit or fire inside the microwave cabinet and shuts down the microwave to prevent injury. This component should be replaced a by a service technician because opening the microwave cabinet to replace the high-limit thermostat exposes you to a high-voltage capacitor that can retain a lethal electrical charge even when the microwave power cord is unplugged from the wall outlet.
• Cavity light bulb. The cavity light bulb illuminates the inside cavity of the microwave when you open the microwave door and when the microwave is cooking.
• Cooking tray. The cooking tray holds foods being cooked inside the microwave cavity and rotates to cook foods evenly.
• Turntable motor. The turntable motor rotates the cooking tray so foods cook evenly inside the microwave.
