Sharp built-in microwave safety precautions

• Never attempt to repair internal microwave components inside the microwave oven cabinet. The high-voltage capacitor inside the microwave retains a lethal electrical charge even when the microwave power cord is unplugged from the wall outlet. Have a service technician repair any internal microwave component failure
• Do not operate the microwave with the door open. Interlock switches should prevent the microwave from starting with the door open.
• Don't use the microwave if you see door damage. A damaged door can allow microwave radiation to leak out of the cavity. Have a service technician repair the microwave door and test the door for radiation leakage.
• Clean food residue out of the microwave cavity often.

Common replacement parts for Sharp 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.
